Weather extremes

How extreme does Salinas's weather get?

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

Based on 50+ years of daily weather observations (1971–present), from the Guayama 1Sw station 18 km away. Updated through June 2026 — 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 Salinas has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
99°F Aug 2, 1978

That is about 9°F hotter than a normal August afternoon in Salinas (typical high near 90°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.

Salinas's record heat sits well above even a hot day for the season — August's 99°F is about 9°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, Salinas's warmest days reach the low 90s°F and its coldest nights drop to the low 70s°F. But across the record it has gone as high as 99°F and as low as 9°F. A single day has delivered over 20 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 Guayama 1sw, a weather station, about 18 km from the city centre. The underlying daily records come from NOAA's global station network.
