ROME · THE 12-MONTH VERDICT · 41.89° N
Rome is a walking city with a Mediterranean thermostat. August averages 87.0°F by day and January 52.8°F, and the rain gauge does almost all of its work between September and December, when the summer sky finally breaks. Most trips fly into Fiumicino for three or four nights, and almost every hour of those nights is spent outdoors between one indoor marvel and the next.
May wins on our reading: 72.4°F days and 2.29 inches of rain across six wet days. November loses on the same measure, 5.10 inches spread over 9.8 wet days. Everything between those two poles is a trade among heat, rain and daylight, and the normals below carry the figures for each month.
THE YEAR AT A GLANCE · ROME
Book May: 72.4°F days, 54.4°F nights, 2.29 inches of rain over six wet days and 14 hours 37 minutes of daylight at mid-month.

Three nights covers the Colosseum, the Vatican and one long walk across the center. Four adds Ostia Antica or Tivoli to the itinerary. That shape barely changes with the season, but the hours available to it do: 15 hours 16 minutes of daylight on June 15 against 9 hours 12 minutes on December 15.
Rome weather month by month: highs, lows and rainfall
| Month | Avg high | Avg low | Rain | Days ≥ 0.10 in |
|---|---|---|---|---|
| January | 52.8°F | 38.4°F | 2.49 in | 6.3 |
| February | 54.2°F | 38.5°F | 2.82 in | 6.7 |
| March | 59.3°F | 42.4°F | 2.96 in | 7.2 |
| April | 64.5°F | 47.2°F | 3.05 in | 7.6 |
| May | 72.4°F | 54.4°F | 2.29 in | 6.0 |
| June | 80.6°F | 61.7°F | 1.31 in | 3.4 |
| July | 86.4°F | 66.9°F | 0.87 in | 2.2 |
| August | 87.0°F | 68.0°F | 0.88 in | 2.3 |
| September | 77.7°F | 61.6°F | 3.20 in | 6.4 |
| October | 69.7°F | 55.2°F | 4.58 in | 8.1 |
| November | 61.0°F | 47.9°F | 5.10 in | 9.8 |
| December | 54.3°F | 40.8°F | 3.63 in | 7.3 |
Summer runs long and dry, autumn pays the bill. July takes 0.87 inch of rain across 2.2 wet days and August 0.88 inch across 2.3, while November collects 5.10 inches over 9.8 days at 0.10 inch or more. Winter is mild rather than cold: January, the coolest month of the twelve, still averages 52.8°F by day.
The year turns twice, and both turns are sharp. Between April and May, highs rise from 64.5°F to 72.4°F while rainfall falls from 3.05 inches to 2.29. Between August and September, highs drop 9.3°F to 77.7°F and rain more than triples, from 0.88 inch to 3.20. October then adds another 1.38 inches on top of September.
November is the wettest of the twelve months, 5.10 inches of it, delivered across 9.8 days at 0.10 inch or more, with 9 hours 52 minutes of daylight on the 15th. Museum-led trips absorb that easily. The traveler it punishes is the one who came to walk the center, cross the river at dusk and eat outside, because those are exactly the hours the month removes.
Every figure here comes from ERA5 model reanalysis for 1991-2020, computed on the grid cell centered at 41.8919° N, 12.5113° E over central Rome, not from an airport station log. That matters for day trips: the coast at Ostia runs milder than these numbers and the hills of Lazio run cooler, so Tivoli in April is not the April in the table.
When is the best time to visit Rome?
May. Highs of 72.4°F, lows of 54.4°F, 2.29 inches of rain across 6.0 days at 0.10 inch or more, and 14 hours 37 minutes of daylight on the 15th, with the sun up at 5:47 a.m. and down at 8:25 p.m. local time. That is a full day on foot without a coat and without shade-hunting, plus a three-hour evening for dinner outdoors. Three nights fit the headline sights, four if a day trip goes on the plan.
June is the obvious rival and loses on comfort. Its highs of 80.6°F sit 8.2°F above May, and its nights hold at 61.7°F rather than 54.4°F, which changes what a top-floor room without air conditioning feels like at 2 a.m. June does buy drier ground, 1.31 inches against 2.29, and 39 more minutes of daylight at mid-month. Trade heat for one extra shower and May takes it.
We keep no dedicated Rome month pages yet, so the normals above carry the detail for May and its neighbors. For the rest of the calendar, our month desk sits at Where to Go, by Month, and the trip-shaping basics, from flight timing to first-day logistics, at Travel 101.
How hot does Rome get in summer?
August is the hottest month at 87.0°F, July a shade behind at 86.4°F, and the nights barely retreat: August lows average 68.0°F, July lows 66.9°F. Rain is close to irrelevant, 0.88 inch across 2.3 wet days in August. Daylight runs 13 hours 54 minutes on August 15, sunrise at 6:17 a.m. and sunset at 8:11 p.m. local, which is where the workable outdoor hours actually are.
Our source gives air temperature and precipitation for that cell and nothing more. We found no humidity or heat-index series on the same 1991-2020 basis, so we cannot tell you how 87.0°F reads along the Tiber at 3 p.m., and we would rather say so than guess. Build the day around what we do have: the ruins early, the galleries at midday, the walking after 6 p.m. while there is still light until eight.
When is Rome quietest?
The quiet stretch is a calendar fact, not a price ranking: the weeks after the Christmas and New Year travel run, through February and into early March, ending whenever Easter falls that year. We found no occupancy or price series for Rome, so we crown no month cheap and no month expensive. What we can say is that this is the part of the year school holidays leave alone.
January still averages 52.8°F by day and February 54.2°F, warm enough to cross the center in a coat rather than a parka. Both are drier than the autumn: 6.3 wet days in January and 6.7 in February, against 9.8 in November. And the collections that fill a rainy morning, the Vatican Museums, the Capitoline, the Galleria Borghese, are indoor days that hold their value whatever the sky is doing.
The light is the price. January 15 gives 9 hours 31 minutes, sunrise 7:33 a.m., sunset 5:04 p.m. local, nearly six hours short of June 15. Add 3.9 nights at or below 32°F in an average January and the same 3.9 in February, and dinner moves indoors for the whole trip. Two short afternoons mean two sights a day, not four.
Which month should you avoid in Rome?
November, if you plan to walk. It is the wettest of the twelve months at 5.10 inches, spread over 9.8 days at 0.10 inch or more, and it offers 9 hours 52 minutes of daylight on the 15th, sunrise 6:58 a.m. and sunset 4:50 p.m. local. Photographers lose the golden hour to a commute, and a day trip to Ostia Antica or the gardens at Tivoli becomes a coin flip.
Cold is not the problem: 61.0°F by day, 47.9°F at night, and 0.0 freezing nights in an average November. Only 1.0 of those 9.8 wet days brings an inch or more, so roughly nine are showers you sit out with a coffee. A three-night museum trip in November works, with an umbrella in the bag and the first entry of the day booked indoors.
Is the shoulder season worth it in Rome?
April and October are the shoulders here. April runs 64.5°F by day, 21.9°F below July’s 86.4°F. October runs 69.7°F, 17.3°F below August’s 87.0°F. Nights follow: 47.2°F in April and 55.2°F in October, against 66.9°F and 68.0°F in the two peak months.
What those numbers buy is a full outdoor day. April carries 13 hours 25 minutes of daylight on the 15th, only 1 hour 51 minutes short of the June peak, and 0.0 nights at freezing, so a four-night trip with a day trip in it stays comfortable on foot from morning to dark. October keeps evening temperatures at 55.2°F, which is a jacket, not a retreat.
Rain is what the shoulder takes back. October collects 4.58 inches across 8.1 wet days, more than five times July’s 0.87 inch, and 1.0 of those days brings an inch or more. April collects 3.05 inches across 7.6 days, against May’s 2.29 across 6.0. October also loses light quickly: 11 hours 8 minutes at mid-month, four hours short of June.
Take April if the trip is walking-led and one wet day in four is acceptable. Take October if school or work fixes the dates, and put the galleries on the mornings rather than the afternoons. If the week is genuinely yours to choose, neither shoulder beats May at 2.29 inches, 6.0 wet days and 14 hours 37 minutes of light.
The last word
If May is gone and November is what the calendar offers, counter with February. Its 54.2°F high sits within a tenth of a degree of December’s 54.3°F, it takes 2.82 inches of rain against December’s 3.63, and mid-February carries 1 hour 27 minutes more daylight than mid-December. Pack for the 3.9 freezing nights, book a bed inside walking distance of the Pantheon so the 5:04 p.m. sunsets cost you nothing, and let the galleries have the afternoons.
