The first thing to understand about weather in Italy is that there really isn’t one Italian climate.
You can be skiing in the Dolomites while someone in Sicily is eating lunch outside in the sun.
Milan can be cold, damp and foggy while Palermo is 15°C (59°F).

Florence can be brutally hot in August while an evening high in the mountains requires a jacket.
Italy stretches more than 1,000 kilometers from the Alps toward the Mediterranean, with mountains running through much of the country. The official Italian tourism board describes the climate as generally mild but extremely variable depending on location and season.
So when someone asks:
“What is Italy like in October?”
my first question is always:
Which Italy?
October in the Dolomites and October in Sicily are two completely different packing lists.
This guide goes through Italy weather month by month, with realistic advice for the places most travelers actually visit: Milan and northern Italy, Venice, Florence and Tuscany, Rome, Naples and the Amalfi Coast, Puglia, Sicily and Sardinia.
Italy weather: north vs central vs south
Before getting into individual months, this distinction will make the rest of the guide much easier to understand.
Northern Italy
Think:
- Milan
- Venice
- Turin
- Bologna
- Lake Como
- Lake Garda
- Dolomites
- Italian Alps
Northern Italy has the biggest seasonal swings.
Winters can be genuinely cold. Snow is normal in mountain areas, while cities such as Milan often have cold, damp winter weather.
Summers can also be very hot.
Do not make the mistake of assuming northern Italy means cool summer weather. Milan and Bologna can be extremely hot and humid in July and August.
Central Italy
Think:
- Florence
- Tuscany
- Rome
- Umbria
- Marche
Winters are generally milder than farther north, particularly around Rome, but Florence can still feel properly cold in January.
Spring and autumn are excellent for sightseeing.
Summer is hot.
Very hot.
Florence averages around 32 to 33°C (90 to 91°F) for daytime highs in July and August, while Rome averages around 32°C (89 to 90°F).
And those are averages, not the maximum temperature you might experience during a heatwave.
Southern Italy and the islands
Think:
- Naples
- Amalfi Coast
- Puglia
- Calabria
- Sicily
- Sardinia
Winters are generally milder.
Summers are hot, sunny and often dry.
The beach season also stretches considerably farther into the shoulder months than it does in northern Italy.
Palermo, for example, averages daytime highs around 15°C (59°F) even in January, rising to approximately 31°C (87°F) in August.
That is why asking for the “average temperature in Italy” without specifying a destination is not particularly useful.
One warning about Italy weather averages
The temperatures in this guide are climate averages, not forecasts.
Weather does not read travel blogs.
You can have 25°C sunshine in Rome in March.
You can also spend three days in Rome in May carrying an umbrella.
And recent Italian summers have been warmer than older averages might lead travelers to expect.
Italy’s environmental protection agency reported that 2025 was 1.03°C warmer than the 1991 to 2020 national climate average, with summer 2025 ranking as the fourth warmest since 1961. June 2025 was 3.23°C above the climatological average.
Italy’s Ministry of Health now runs city-specific heatwave alerts from May through September.
So use monthly averages to choose when to travel.
Use an actual weather forecast to decide what goes into your suitcase three days before you leave.
Very different jobs.
Italy Weather in January
Typical daytime highs:
Milan: around 7°C / 45°F
Rome: around 13°C / 55°F
Florence: around 11°C / 52°F
Palermo: around 15°C / 59°F
January is one of the coldest months in Italy.
But again, the experience depends enormously on where you are.
In Milan, mornings can hover around freezing. Northern plains can be damp and grey, and winter fog is part of the experience.
Florence is cold enough for a proper coat.
Rome is noticeably milder, particularly in the middle of a sunny day.
Sicily can feel surprisingly pleasant when the sun is out, although you should not interpret “15°C in Palermo” as beach weather.
January is excellent if your priority is cities rather than beaches.
Rome, Florence and Venice are far easier to walk around without summer heat. You will still encounter visitors, particularly around major holidays, but the physical experience of spending six hours walking through Rome is completely different from July.
In the Alps and Dolomites, January is firmly ski season.
What to pack for Italy in January
Bring:
- warm coat
- layers
- comfortable waterproof shoes
- scarf
- umbrella or rain jacket
- warmer accessories for northern Italy
For Sicily and southern coastal areas, layers are more useful than one enormous winter coat.
A sunny afternoon can feel mild.
The moment the sun disappears, January remembers what month it is.
Italy Weather in February
Typical daytime highs:
Milan: around 11°C / 51°F
Rome: around 14°C / 58°F
Florence: around 13°C / 55°F
Palermo: around 15°C / 59°F
February is still winter.
Northern Italy remains cold, and the mountains remain firmly in ski mode.
Rome and Florence begin to show occasional hints of spring, but you should not pack as though spring has officially won the argument.
It hasn’t.
Expect cool days, cold mornings and the possibility of rain.
February can be a very good month for museum-heavy city trips.
It is not the month I would choose for the Amalfi Coast if your dream involves long dinners beside the sea and swimming from Positano.
Many coastal destinations feel much quieter in winter, and some seasonal tourism businesses operate reduced schedules or close entirely.
That does not make southern Italy bad in February.
It makes it different.
February is best for
- Rome without summer heat
- Florence museums
- Venice, particularly around Carnival when dates coincide
- skiing in northern Italy
- food-focused city trips
Bring proper winter clothing, particularly north of Rome.
Italy Weather in March
Typical daytime highs:
Milan: around 16°C / 60°F
Rome: around 17°C / 62°F
Florence: around 16°C / 61°F
Palermo: around 17°C / 62°F
March is where packing for Italy becomes slightly ridiculous.
You may need sunglasses.
You may need a rain jacket.
You may need both within 45 minutes.
March is a transition month.
Temperatures are noticeably warmer than January and February, particularly later in the month, but weather can change quickly.
For city sightseeing, this can be excellent.
Rome at 16 or 17°C is lovely walking weather.
Florence starts feeling more like spring.
Milan is still capable of giving you a cold, wet day just when you confidently leave your coat at the hotel.
Southern Italy starts becoming particularly attractive.
Sicily, Puglia and Campania can have beautiful sunny periods without summer temperatures.
I would still not plan a March trip around guaranteed swimming.
Plan it around sightseeing, food and walking.
If the weather gives you something extra, take it.
Italy Weather in April
Typical daytime highs:
Milan: around 19°C / 67°F
Rome: around 19°C / 67°F
Florence: around 20°C / 68°F
Palermo: around 19°C / 66°F
April is one of those months that looks perfect on paper.
Temperatures are mild.
Flowers are out.
Days are longer.
You can comfortably walk around cities for hours.
Italy’s official tourism site specifically promotes spring for outdoor travel, villages, lakes and countryside because of the milder conditions.
And I do like April.
I just would not call it guaranteed sunny Italy.
Rain is entirely possible.
Florence averages noticeably more precipitation in April than in the dry summer months, and Milan also sees meaningful spring rainfall.
The correct April packing strategy is not to obsess over whether it will rain.
Bring something waterproof.
Problem solved.
Is April a good month to visit Italy?
Yes, especially for:
- Rome
- Florence
- Venice
- Tuscany
- Bologna
- Naples
- Sicily
- Puglia
The major caveat is Easter.
Easter dates change each year, and the holiday period can make some famous destinations significantly busier.
Weather may be shoulder season.
Visitor numbers do not always cooperate.
Italy Weather in May
Typical daytime highs:
Milan: around 24°C / 76°F
Rome: around 24°C / 76°F
Florence: around 24°C / 76°F
Palermo: around 23°C / 73°F
If you asked me to choose one of the best months for a classic Italy trip based mainly on weather, May would be near the top.
Days are warm without usually having the relentless heat of July and August.
Evenings are pleasant.
The countryside is green.
You can walk Rome.
You can walk Florence.
You can walk Venice.
This sounds obvious until you have tried walking 22,000 steps across Rome when the temperature is 37°C.
May can still bring rain, particularly in northern and central Italy.
Milan’s historical averages actually show more precipitation in May than during midsummer.
But from a travel perspective, I would happily accept the possibility of a rainy afternoon in exchange for temperatures around the low to mid-20s Celsius.
Can you swim in Italy in May?
Possibly, especially later in May and particularly in southern Italy.
But I would not build a northern or central Italy May trip around guaranteed warm sea temperatures.
Sicily, Sardinia and parts of southern Italy give you the best chance.
If swimming is the main purpose of the holiday, June or September is a safer choice.
If sightseeing is the main purpose and a beach day would be a bonus, May is excellent.
Italy Weather in June
Typical daytime highs:
Milan: around 28°C / 83°F
Rome: around 29°C / 84°F
Florence: around 29°C / 85°F
Palermo: around 27°C / 81°F
June is summer.
Not “almost summer.”
Summer.
The first half of June can be particularly lovely because days are long and the most intense summer heat may not have arrived yet.
By late June, however, Rome and Florence can be seriously hot.
Recent climate data is worth keeping in mind here. June 2025 was the second-warmest June recorded in Italy’s national series, at 3.23°C above the 1991 to 2020 average.
So do not look at a historical June average of 29°C and assume 29°C is the hottest temperature you could possibly encounter.
Is June a good month for Italy?
Yes.
It is particularly strong for:
- Amalfi Coast
- Sicily
- Sardinia
- Puglia
- Italian lakes
- Tuscany
- northern mountains
- beach-and-city combinations
For Rome and Florence, start sightseeing early.
An 8 a.m. walk and a 2 p.m. walk are technically happening in the same city.
Emotionally, they are not the same experience.
Italy Weather in July
Typical daytime highs:
Milan: around 31°C / 87°F
Rome: around 32°C / 89°F
Florence: around 32°C / 90°F
Palermo: around 29°C / 85°F
July is hot.
There is no need to make this more poetic.
Rome is hot.
Florence is hot.
Milan is hot and can be humid.
Bologna is hot.
Southern Italy is hot.
The difference is that when you are beside the sea in Sicily, Amalfi or Sardinia, hot weather is often exactly what you came for.
When you are standing in a queue outside an attraction in Florence at 1:45 p.m., your feelings may differ.
Is July too hot for Italy?
Not necessarily.
But it depends on the trip.
Excellent July trip:
Sardinia, Sicily, Puglia or a coastal itinerary with mornings in towns and afternoons beside the water.
More demanding July trip:
Rome + Florence + Venice with full sightseeing days from breakfast until dinner.
You can absolutely do it.
Millions of people do.
Just plan around the heat rather than pretending it is not there.
Start early.
Book timed attractions.
Take breaks.
Carry water.
Have lunch somewhere cool.
Italy’s Ministry of Health publishes heatwave alerts for 27 cities throughout the summer because periods of extreme heat can present genuine health risks.
“Just push through it” is not an itinerary strategy.
Italy Weather in August
Typical daytime highs:
Milan: around 31°C / 87°F
Rome: around 32°C / 90°F
Florence: around 33°C / 91°F
Palermo: around 31°C / 87°F
August is usually the month when people underestimate Italy most dramatically.
You see:
Average Florence high: 33°C / 91°F
and think:
“Fine. I have experienced 33°C before.”
Yes.
But perhaps not while climbing to Piazzale Michelangelo after spending three hours in the Uffizi.
Average temperatures also hide heatwaves.
August can move well beyond the monthly average.
Where is best in Italy in August?
For weather alone, I would look toward:
- Sardinia
- Sicily
- Puglia
- Amalfi Coast
- Liguria
- Italian lakes
- Dolomites
- Alps
Italy’s official tourism site highlights both the seaside and mountains as major summer destinations.
The mountains are particularly useful if you want an Italian summer without spending every afternoon searching for air conditioning.
Is Rome worth visiting in August?
Yes, if August is when you can travel.
But build a heat-conscious itinerary.
Go out early.
Rest during the worst afternoon heat.
Come back outside in the evening.
You do not receive extra cultural points for seeing the Roman Forum at the hottest possible time of day.
Italy Weather in September
Typical daytime highs:
Milan: around 26°C / 78°F
Rome: around 27°C / 81°F
Florence: around 27°C / 81°F
Palermo: around 27°C / 81°F
September is one of my favorite months for Italy.
But there is a difference between September 3 and September 28.
Early September can still feel like full summer.
Rome and Florence can remain very warm.
Sicily is still beach territory.
By late September, evenings become cooler, rainfall becomes more possible and northern Italy begins shifting into autumn.
Is September a good month to visit Italy?
Very.
For a trip combining:
- cities
- countryside
- beaches
- walking
- food
- sightseeing
September is difficult to beat.
The sea has had all summer to warm up, which makes September particularly attractive for coastal destinations.
ISPRA reported that Italian sea-surface temperatures in 2025 averaged above the long-term baseline, with national monthly sea-surface averages exceeding 26°C in both July and August.
By September, southern coastal Italy can still feel thoroughly summery.
One mistake to avoid
Do not pack for September as though it is one uniform season.
For early September in Sicily, think summer.
For late September in the Dolomites, think layers and rapidly changing mountain weather.
Same country.
Same month.
Completely different suitcase.
Italy Weather in October
Typical daytime highs:
Milan: around 19°C / 66°F
Rome: around 23°C / 73°F
Florence: around 22°C / 71°F
Palermo: around 24°C / 75°F
October is one of the most interesting months in Italy.
In Rome, an afternoon can still feel wonderfully warm.
In Sicily, 24°C daytime averages make October feel far removed from northern European autumn.
In Milan, you will know summer is over.
And in the mountains, the hiking season is beginning to wind down at higher elevations.
Is October a good month to visit Italy?
For cities, absolutely.
Rome in October can be excellent.
Florence is far easier to walk than in August.
Southern Italy can be lovely.
Sardinia’s official tourism content specifically notes that autumn can still bring mild temperatures and opportunities to enjoy coastal life.
The trade-off is rain.
October is noticeably wetter than summer in many parts of Italy.
Historical averages show October precipitation around:
- 2.87 inches in Milan
- 2.94 inches in Rome
- 3.56 inches in Florence
- 3.78 inches in Palermo
That does not mean it rains all day.
It means the odds of needing that umbrella have increased substantially since July.
Italy Weather in November
Typical daytime highs:
Milan: around 13°C / 55°F
Rome: around 18°C / 64°F
Florence: around 16°C / 61°F
Palermo: around 20°C / 68°F
November is underrated if you like cities and do not require perfect weather.
It is also one of the wetter months.
In the historical datasets used here, November is the wettest month of the year in Milan, Rome and Florence.
That sounds terrible until you remember that “wettest month” does not mean “continuous rain for 30 days.”
You can have beautiful November weather.
You can also have three grey, rainy days in a row.
This is why I would not book November for a trip whose success depends entirely on:
sunset boat ride + beach + vineyard picnic + outdoor dinner.
For Rome museums, churches, restaurants and long lunches?
Different story.
Where is warmest in Italy in November?
Southern Italy and the islands.
Palermo averages around 20°C (68°F) during the day, considerably milder than Milan at around 13°C (55°F).
If you want late-autumn Italy with the best chance of mild weather, look south.
Italy Weather in December
Typical daytime highs:
Milan: around 8°C / 46°F
Rome: around 13°C / 56°F
Florence: around 12°C / 53°F
Palermo: around 16°C / 61°F
December is winter, but Italian winter has several personalities.
Milan is cold.
Florence requires a winter coat.
Rome is chilly rather than brutally cold on most days.
Palermo remains relatively mild, although December is historically its wettest month in the climate dataset used here.
In the mountains, winter sports season begins properly as snow conditions develop.
In the cities, December is about Christmas lights, markets, churches, museums and eating things that make walking slightly more difficult afterwards.
Is December a good month for Italy?
Yes, if you want:
- Christmas atmosphere
- winter city breaks
- museums
- food
- skiing
- fewer expectations of sunshine
No, if what you have imagined is:
Amalfi Coast, linen shirt, swimming, sunset Aperol Spritz.
Save that trip for another month.
What is the best month to visit Italy?
For a classic sightseeing trip, my strongest weather choices are:
May
and
September.
Both give you a good chance of warm weather without building the entire itinerary around surviving the afternoon.
If I wanted slightly cooler sightseeing weather, I would choose:
April
or
October.
If I wanted a beach trip:
June or September.
If I wanted skiing:
January or February.
If I wanted cities with the lowest expectation of warm weather and was happy carrying a coat:
January, February, November or December.
There is no single best month.
There is a best month for the trip you are actually taking.
Best time to visit Rome for weather
My favorites are:
April, May, late September and October.
Rome involves enormous amounts of walking.
Weather that feels slightly cool when you leave the hotel often feels perfect after 15,000 steps.
July and August are completely possible, but you need to plan around heat.
January and February can be surprisingly enjoyable if museums, churches and food are the priority.
Best time to visit Florence for weather
I particularly like:
April, May, late September and October.
Florence’s summer temperatures are worth taking seriously.
Historical averages put July highs around 32°C (90°F) and August around 33°C (91°F).
Add stone streets, crowds and limited shade, and Florence can feel hotter than the number suggests.
If you travel in July or August, book major sights early in the morning where possible.
Best time to visit Venice for weather
For comfortable walking:
April, May, September and early October are strong choices.
Summer is warmer and busier.
Winter can be atmospheric and cold.
Autumn brings a greater chance of unsettled weather.
Venice is also one of those cities where the difference between a glorious sunny day and a wet windy day feels enormous because you spend so much time outside.
Bring shoes you trust.
Fashion has limits.
A soaked sock discovers them quickly.
Best time to visit the Amalfi Coast
For me:
May, June and September offer the nicest balance.
May is excellent for sightseeing and walking, although swimming conditions are less reliable.
June feels properly summery.
September remains warm and is excellent for combining the sea with towns and walking.
July and August are perfect if your priority is hot beach weather and you accept peak-summer heat.
October can still be lovely, particularly early in the month, but weather becomes less predictable.
Best time to visit Sicily
Sicily has one of the longest useful travel seasons in Italy.
For sightseeing:
April, May, October and early November can be excellent.
For beaches:
June through September is the safest window.
September is particularly attractive if you want both sightseeing and swimming.
Palermo’s historical average daytime high remains around 27°C (81°F) in September and 24°C (75°F) in October.
That is why southern Italy can extend your summer considerably.
Best time to visit the Dolomites
This depends entirely on what you want to do.
For skiing:
winter.
For hiking:
summer into early autumn, subject to trail conditions and altitude.
Do not use Rome’s weather forecast to decide what to pack for the Dolomites.
Mountain temperatures can be dramatically lower, weather can change quickly and higher elevations operate by completely different rules.
Your cute Italian city cardigan is not mountaineering equipment.
What is the hottest month in Italy?
Generally, July and August are the hottest months, although the exact answer depends on location.
Rome’s long-term dataset gives August an average high around 32°C (90°F).
Florence reaches approximately 33°C (91°F) in August.
Milan averages about 31°C (87°F) in both July and August.
Palermo averages about 31°C (87°F) in August.
Actual heatwaves can push temperatures significantly higher than those averages.
What is the coldest month in Italy?
Usually January, although local climates vary.
Milan’s average January high is around 7°C (45°F) with lows around freezing.
Rome averages approximately 13°C (55°F) during the day.
Palermo is considerably milder at around 15°C (59°F).
The Alps and Dolomites are another category entirely.
What is the rainiest month in Italy?
There is no single rainiest month for the whole country.
Italy’s rainfall patterns vary by region.
In the historical city datasets used here:
Milan: November is wettest.
Rome: November is wettest.
Florence: November is wettest.
Palermo: December is wettest.
Broadly speaking, autumn is wetter than midsummer in many of the places tourists visit.
But this is exactly why national averages can mislead.
A wet November in Florence does not tell you what is happening in Cagliari.
When can you swim in Italy?
For a conventional beach holiday, think:
June through September.
July and August provide the most reliably hot beach weather.
June is excellent before the peak of summer.
September is one of my favorites because the sea has warmed all summer while daytime temperatures become slightly easier for sightseeing.
In southern Italy and the islands, good swimming conditions can extend into October in warm years.
In May, swimming is possible, particularly in the south, but I would treat it as a bonus rather than a guarantee.
Is Italy too hot in July and August?
For some travelers, yes.
This is particularly relevant if your itinerary is:
Rome + Florence + Venice
with eight hours of sightseeing every day.
For a coastal holiday, the same weather may feel exactly right.
The mistake is not visiting Italy in August.
The mistake is designing an August itinerary as though you are visiting in April.
During hot periods:
- sightsee early
- reserve timed attractions
- carry water
- use fountains where potable water is available
- schedule a proper lunch break
- avoid the most exposed walking at midday
- check official heat alerts
Italy’s Ministry of Health runs heatwave monitoring for 27 cities from late May into September.
Should you trust an Italy weather forecast months in advance?
No.
A climate average can help you decide whether to book Italy in March or August.
A long-range app forecast should not decide whether you cancel your May holiday because it shows a rain cloud 19 days away.
For practical travel planning:
Months before: use climate averages.
One week before: begin watching the forecast.
Two or three days before: make actual clothing and activity decisions.
And even then, put the tiny umbrella in your bag.
Italy likes improvisation.
The weather has embraced the national culture.
Frequently asked questions about Italy weather by month
What is the best month to visit Italy?
For a classic sightseeing trip, May and September offer one of the best combinations of warm weather and manageable temperatures. April and October are excellent if you prefer cooler sightseeing weather.
What months are summer in Italy?
Meteorological summer is June, July and August. June is already warm throughout most of Italy, while July and August are generally the hottest months.
What months are winter in Italy?
Winter is December, January and February. Northern Italy can be cold, while southern Italy and Sicily have considerably milder winters.
What is Italy like in April?
April is generally mild and excellent for sightseeing, with daytime highs around 19°C (67°F) in Rome and Milan and 20°C (68°F) in Florence. Rain is possible, so bring layers and something waterproof.
Is Italy warm in May?
Yes. Rome, Florence and Milan all average daytime highs around 24°C (76°F) in May.
Is Italy hot in June?
Usually, yes. Average June daytime highs are approximately 28°C (83°F) in Milan, 29°C (84°F) in Rome and 29°C (85°F) in Florence.
Is Italy too hot in August?
August can be extremely hot for intensive city sightseeing, particularly in Rome and Florence. Average daytime highs are around 32°C (90°F) in Rome and 33°C (91°F) in Florence, with heatwaves capable of producing substantially higher temperatures.
Is September still hot in Italy?
Early September often feels like summer. Rome and Florence average highs around 27°C (81°F), while Palermo is also around 27°C (81°F). Temperatures generally become cooler later in the month.
Is Italy warm in October?
Central and southern Italy can still be very pleasant. Rome averages around 23°C (73°F) during the day and Palermo around 24°C (75°F). Milan is cooler at roughly 19°C (66°F).
Does it snow in Italy?
Yes. Snow is normal in Italy’s Alpine and high-mountain regions during winter. Snow in lowland and central Italian cities is much less reliable and should not be expected as part of a normal winter city trip.
When is the rainy season in Italy?
There is no nationwide rainy season, but autumn is relatively wet in many popular Italian cities. November is historically the wettest month in the Milan, Rome and Florence datasets used in this guide.
What is the best month for an Italy beach holiday?
June and September are excellent if you want warm beach weather while avoiding some of the intensity of July and August. For the hottest and most reliable summer beach conditions, choose July or August.
What should I pack for Italy?
The city and month matter more than the word “Italy.”
January in Milan requires winter clothing.
April in Rome requires layers.
July in Florence requires light clothing and serious sun protection.
October in Sicily may still involve short sleeves during the day.
Before packing, check the forecast for every major stop on your itinerary.
Because there is no weather forecast called “Italy.”
And if your trip runs from Milan to Rome to Sicily, your suitcase is about to discover that personally.
