Weather extremes

How extreme does Rome's weather get?

The hottest, coldest, wettest and snowiest days Rome has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1971–present), from the Roma Ciampino station 13 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Rome has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
105°F Aug 4, 1981

That is about 16°F hotter than a normal August afternoon in Rome (typical high near 89°F).

🌧️ Most rain in one day
7.90 in May 30, 2010

More rain in a single day than Rome usually gets in the whole month of May (typical May total about 2.3 in).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Rome's record heat sits well above even a hot day for the season — August's 105°F is about 16°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Rome's warmest days reach the high 80s°F and its coldest nights drop to the high 30s°F. But across the record it has gone as high as 105°F and as low as 12°F. A single day has delivered over 8 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 25 years of daily observations at Roma Ciampino, a weather station, about 13 km from the city centre. The underlying daily records come from NOAA's global station network.
