How extreme does Santa Clara's weather get?

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

Based on 20 years of daily weather observations (2005–present), from the Abel Santamaria station 10 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, Santa Clara has reached as high as 102°F and as low as 39°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 29 years of daily observations at Juan Gualberto Gomez Intl, a weather station, about 166 km from the city centre. The underlying daily records come from NOAA's global station network.
