Beyond temperature, Silverton averages 23.9 inches of precipitation annually, with 172.6 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. Growing-season length varies with elevation and microclimate. Turning to energy use, 11,035 heating degree days and 0 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Silverton scores 47/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
