Cohagen averages 12.3 inches of precipitation a year, with 24.6 inches typically falling as snow, and that matters as much to daily life here as temperature does. The frost-free season averages 112 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 25 and the first fall freeze near September 14. As for energy demand, 8,181 heating degree days and 408 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Cohagen scores 39/100 (Below Average), 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 July-driven heat, or deep winter for January-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.
