How extreme does Santarém's weather get?

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

Based on 26 years of daily weather observations (1999–present), from the Alverca station 49 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

In plain terms

Across the record, Santarém has reached as high as 108°F and as low as 30°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.

Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Lisboa/gago Coutinho, a weather station, about 65 km from the city centre. The underlying daily records come from NOAA's global station network.
