How extreme does Aveiro's weather get?

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

Based on 21 years of daily weather observations (2004–present), from the Ovar station 30 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.
