How extreme does Romans-sur-Isère's weather get?

The hottest, coldest, wettest and snowiest days Romans-sur-Isère 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 Montelimar station 58 km away. Updated through February 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

Romans-sur-Isère's record heat sits well above even a hot day for the season — August's 106°F is about 21°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, Romans-sur-Isère's warmest days reach the mid-80s°F and its coldest nights drop to the high 30s°F. But across the record it has gone as high as 106°F and as low as 6°F. A single day has delivered over 9 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
