Dewey averages an uncharted amount of precipitation a year, predominantly as rainfall, and that matters as much to daily life here as temperature does. The frost-free season averages 165 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 27 and the first fall freeze near October 9. As for energy demand, 4,991 heating degree days and 1,392 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Dewey scores 59/100 (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 January-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.
