How extreme does Chillán's weather get?

The hottest, coldest, wettest and snowiest days Chillán 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 General Bernardo O Higgins station 7 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.

In plain terms

In a normal year, Chillán's warmest days reach the high 80s°F and its coldest nights drop to the high 40s°F. But across the record it has gone as high as 107°F and as low as 15°F. A single day has delivered over 6 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
