Chilly Barton Flat receives roughly 8.0 inches of precipitation each year, with 18.3 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near June 14 and the first fall freeze near September 8. For energy use, 8,818 heating degree days and 92 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Chilly Barton Flat scores 37/100 (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.
