Weather extremes

How extreme does Spokane Valley's weather get?

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

Based on 28 years of daily weather observations (1998–present), from the Spokane Felts Fld station 6 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 Spokane Valley has recorded — each shown against what a normal day that time of year looks like.

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.

Spokane Valley's record heat sits well above even a hot day for the season — June's 113°F is about 37°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, Spokane Valley's warmest days reach the high 80s°F and its coldest nights drop to the mid-20s°F. But across the record it has gone as high as 113°F and as low as −10°F. A single day has delivered over 2 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
