Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Humptulips Salmon Hatchery receives roughly 115.6 inches of precipitation each year, with 1.0 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 26 and the first fall freeze near October 22. For energy use, 5,937 heating degree days and 27 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Humptulips Salmon Hatchery scores 52/100 (Moderate), 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.
