Best Time to Visit Italy
Go in May or October. May in Rome ran 23.7°C / 74.7°F by day and 13.5°C / 56.3°F at night with rain on just 8 days; October ran 22.5°C / 72.5°F and 12.5°C / 54.5°F with 9 rainy days. Both give you the warmth people picture when they imagine Italy without the June peak of 33.9°C / 93.0°F, which is the temperature that turns a day of walking Rome into a day of hiding from Rome. April is the third good option — 20.1°C / 68.2°F, 74.4mm of rain, the lowest rainfall total of any month outside the summer dry spell.
All figures below are measured 2025 data for Rome. Northern Italy (Milan, Venice, the Dolomites) runs colder and damper; the far south and Sicily run hotter and drier. Rome sits close to the national middle, which is why it's the useful reference point.

The best months and what the weather is actually like
May is the strongest month on the numbers. A 23.7°C / 74.7°F afternoon is short-sleeve weather where a stone piazza in direct sun is pleasant rather than punishing, and the 13.5°C / 56.3°F low means an evening outside at a restaurant table works with a light layer over your shoulders. The 10.2°C spread between high and low is the thing to plan for — you will genuinely want a jacket at 10pm and genuinely won't want it at 2pm.
May's rainfall looks moderate at 101.4mm / 4.0in, but the shape matters more than the total: that fell across only 8 days, which averages 12.7mm per wet day. That is not drizzle. It is a proper hour of rain, usually building through the afternoon, then clearing. The practical read is that in a 10-day May trip you should expect two or three afternoons where you duck into a church or a café for an hour, not two or three days written off.
October is May's mirror image and slightly drier in absolute terms: 88.2mm / 3.5in across 9 days, about 9.8mm per wet day. Days peak at 22.5°C / 72.5°F, which is warm enough for a full day outdoors and cool enough that a 3pm walk uphill doesn't leave you soaked. Nights at 12.5°C / 54.5°F are a real drop — this is the month people underpack for, because they check the daytime high, see 22.5°C, and leave the jacket at home.
April is the quiet third choice. It has the most rain days of the three (11), but the lowest total (74.4mm / 2.9in), so each wet day averages 6.8mm — the lightest per-day rainfall of any month in the year outside June. Eleven light showers is a very different trip from six downpours. The trade is temperature: 20.1°C / 68.2°F by day and 10.4°C / 50.7°F at night is early-spring weather, comfortable for walking but too cool for the long outdoor evenings May gives you.
The months to avoid and why
June is the hottest month of the year, and by a wide margin: 33.9°C / 93.0°F. That is higher than July (32.9°C / 91.2°F) and August (32.8°C / 91.0°F), which surprises people who assume Italian heat climbs steadily to an August peak. It also barely rains — 15.7mm / 0.6in over 3 days — so there is no afternoon storm to break the heat and no cloud to sit under. Combined with a 20.9°C / 69.6°F overnight low, buildings without air conditioning never fully cool down before the next day starts.
July is only 1.0°C cooler than June and just as dry in practice: 40.9mm / 1.6in over 4 days. What that arithmetic means is 10.2mm per wet day — when it does rain in July, it rains hard and briefly, then the heat comes straight back with the humidity raised. Nights are the year's warmest at 21.7°C / 71.1°F.
August holds 32.8°C / 91.0°F but shifts wetter: 65.1mm / 2.6in across 9 days. Nine wet days at 32.8°C is worse than it sounds — it isn't relief, it's humidity. August also carries the non-weather problem: it's when Italians take their own holidays, so a share of the family-run restaurants and small shops you actually wanted to visit are shut, while every coastal town is at capacity.
The fourth month to think twice about is March, for the opposite reason. It is the wettest month by number of rainy days — 15 of them, 150.4mm / 5.9in total, roughly 10.0mm per wet day. Half the month wet at 16.9°C / 62.4°F is the combination that ruins walking days: not warm enough to dry off, not brief enough to wait out.
Shoulder season — cheaper but still fine
The genuine value windows are late October into November and March into early April, and only one of them is worth it.
November is the better bargain than its reputation suggests. Daytime highs of 16.8°C / 62.2°F are sweater weather, not winter, and the 9 rain days are the same count as October. What changes is intensity: 114.6mm / 4.5in over those 9 days works out to 12.7mm per wet day, the same per-day rate as May. So November is not a permanently grey month — it's roughly three weeks of cool, usable, uncrowded days punctuated by nine genuinely wet ones. If your itinerary is museums, churches, and food, that is a strong trade for off-season pricing. If it's coastline and hilltop views, it isn't.
The March side of the shoulder is the one to skip, for the 15-rain-day reason above. If you need a spring shoulder trip, push it to the first half of April: you get 20.1°C / 68.2°F, the year's lowest per-day rainfall, and prices that haven't yet climbed to May levels.
September deserves its own note because it's marketed as the perfect shoulder month and the data complicates that. Temperatures are lovely — 27.7°C / 81.9°F day, 17.8°C / 64.0°F night, the best evening weather of the entire year. But September recorded 162.4mm / 6.4in of rain, the highest total of any month, across only 6 days. That is 27.1mm per wet day, more than double any other month's intensity. Six days of that in a month means genuine thunderstorms — the sky goes dark, streets flood for twenty minutes, and then it's 27°C again. Plan September around it rather than against it: it is still a very good month, but do not schedule anything unmissable outdoors without a fallback.
What each season means practically
Spring (March–May)
You are layering. March at 16.9°C / 62.4°F with 15 wet days means a real waterproof jacket, not a windbreaker, plus shoes you don't mind soaking. By May at 23.7°C / 74.7°F you're in short sleeves during the day and carrying one light layer for the 13.5°C / 56.3°F evening. Spring is when you do the walking-heavy days — the Forum, Pompeii, hill towns — because you can be outside for six hours without needing shade.
Summer (June–August)
You are working around the sun. At 33.9°C / 93.0°F in June, the middle of the day is not usable for outdoor sightseeing, and shifting to an 8am start and a 6pm second session is the difference between enjoying the trip and enduring it. Pack for sweat, not for style: light natural fabrics, a hat, a refillable bottle (Rome's street fountains run all summer), and more changes of clothes than the trip length suggests. Confirm air conditioning before booking anything, because 20.9°C / 69.6°F nights do not cool a room on their own.
Autumn (September–November)
You are carrying an umbrella but wearing less than you'd think. September at 27.7°C / 81.9°F is still full summer clothing with a storm plan attached. October at 22.5°C / 72.5°F is the single most comfortable dressing month of the year — one layer by day, one more after dark. November at 16.8°C / 62.2°F is a coat month with 8.1°C / 46.6°F nights, and the point where indoor plans should form the backbone of the itinerary.
Winter (December–February)
You are cold but not frozen, and mostly indoors. December peaks at 13.7°C / 56.7°F and drops to 5.6°C / 42.1°F; January runs 14.0°C / 57.2°F and 6.6°C / 43.9°F; February 14.8°C / 58.6°F and 5.8°C / 42.4°F. Those lows are near-freezing at night but never sustained snow weather in Rome. Rainfall is modest — January is the driest non-summer month at 53.6mm / 2.1in over 10 days, averaging 5.4mm per wet day, which is drizzle. Winter means a warm coat, waterproof shoes, and an itinerary built on the Vatican Museums, galleries, and long lunches rather than gardens and viewpoints.
Month-by-month
- January — 14.0°C / 57.2°F, 53.6mm over 10 days. The driest wet-season month; cold, quiet, cheapest.

- March — 16.9°C / 62.4°F, 150.4mm over 15 days. Half the month wet. Skip it.
- April — 20.1°C / 68.2°F, 74.4mm over 11 days. Lightest showers of the year; good value before May pricing.
- May — 23.7°C / 74.7°F, 101.4mm over 8 days. The best all-round month.
- June — 33.9°C / 93.0°F, 15.7mm over 3 days. Hottest and driest. Avoid.

- August — 32.8°C / 91.0°F, 65.1mm over 9 days. Hot, humid, and half the good places are closed.
- September — 27.7°C / 81.9°F, 162.4mm over just 6 days. Beautiful, with the year's most violent storms.
- October — 22.5°C / 72.5°F, 88.2mm over 9 days. Ties May for the best month; better for crowds.
- November — 16.8°C / 62.2°F, 114.6mm over 9 days. Underrated if your plans are indoors.
- December — 13.7°C / 56.7°F, 69.0mm over 7 days. Coldest month; fewest wet days after summer.
FAQ
Is August really as bad as everyone says?
The temperature isn't the worst part — August at 32.8°C / 91.0°F is actually 1.1°C cooler than June. The problem is the combination: 9 rainy days at that temperature means humidity, 21.4°C / 70.5°F nights mean rooms don't cool, and August is the month Italians take their own holidays, so family-run businesses close and coastal towns run at capacity. June is hotter; August is more unpleasant.
What's the cheapest time to go without ruining the trip?
Late October into November. November's 16.8°C / 62.2°F daytime high is comfortable walking weather, and its 9 rainy days are the same count as October's — the rain is heavier per day (12.7mm vs 9.8mm), but the number of days you lose is identical. January is cheaper still at 53.6mm / 2.1in of drizzle across 10 days, but 6.6°C / 43.9°F nights make it a museums-and-restaurants trip rather than a walking one.
Will it rain the whole time if I visit in September?
No — September's 162.4mm / 6.4in is the year's highest rainfall total, but it fell on only 6 days. That's 27.1mm per wet day, meaning short violent thunderstorms rather than steady grey. Twenty-four days of the month were dry, at 27.7°C / 81.9°F. Build in flexibility rather than avoiding the month.
How much do I actually need to pack for temperature swings?
One extra layer, in every month except deep summer. The day-to-night gap runs about 10°C year-round — 10.2°C in May (23.7 to 13.5), 10.0°C in October (22.5 to 12.5), 8.7°C in November (16.8 to 8.1). June has the largest swing at 13.0°C (33.9 to 20.9), but a 20.9°C / 69.6°F "low" needs nothing extra. So: spring and autumn need a light jacket you'll carry all afternoon, winter needs a proper coat over 5–6°C nights, and summer needs nothing but a change of shirt.
