Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Seattle Sand PT Wsfo receives roughly 37.8 inches of precipitation each year, with 3.8 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near March 8 and the first fall freeze near November 23. For energy use, 4,483 heating degree days and 211 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Seattle Sand PT Wsfo scores 72/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for August-driven heat, or deep winter for December-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
