Weather extremes

How extreme does Quimper's weather get?

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

Based on 34 years of daily weather observations (1991–present), from the Quimper Pluguffan station 6 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 Quimper has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
96°F Jul 18, 2022

That is about 26°F hotter than a normal July afternoon in Quimper (typical high near 71°F).

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.

Quimper's record heat sits well above even a hot day for the season — July's 96°F is about 26°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, Quimper's warmest days reach the low 70s°F and its coldest nights drop to the high 30s°F. But across the record it has gone as high as 96°F and as low as 16°F. A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
