Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Fairfield sees about an uncharted amount of precipitation a year, predominantly as rainfall. The frost-free season averages 139 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 12 and the first fall freeze near September 28. On the energy side, 8,602 heating degree days and 446 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Fairfield 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.
