Climate Insight: Spokane, WA
An annual average temperature of 49°F, ranging from a mean daily high of 58°F to a mean daily low of 39°F is what the NOAA 1991–2020 climate normals report for Spokane, Washington. July is typically the warmest month of the year, while December is the coldest. That baseline comes from 3 weather stations and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Spokane sees about 16.4 inches of precipitation a year, with 45.4 inches typically falling as snow. The frost-free season averages 169 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 26 and the first fall freeze near October 12. On the energy side, 6,463 heating degree days and 515 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Spokane scores 49/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings December-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
