Corvallis Water Bureau receives roughly 68.8 inches of precipitation each year, with 5.3 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 15 and the first fall freeze near October 8. For energy use, 5,667 heating degree days and 139 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Corvallis Water Bureau scores 47/100 (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.
