Weather extremes

How extreme does Cerdanyola del Vallès's weather get?

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

Based on 17 years of daily weather observations (2008–present), from the Sabadell-Parc Agrari station 10 km away. Updated through December 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.

Cerdanyola del Vallès's record heat sits well above even a hot day for the season — July's 106°F is about 19°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, Cerdanyola del Vallès's warmest days reach the high 80s°F and its coldest nights drop to the mid-30s°F. But across the record it has gone as high as 106°F and as low as 20°F. A single day has delivered over 4 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
