July is typically the warmest month of the year, while December is the coldest.

Anyone planning to live, garden, or travel in Fenn RS should weigh precipitation alongside temperature: the annual average runs 40.6 inches, with 43.1 inches typically falling as snow. The frost-free season averages 177 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 26 and the first fall freeze near October 20. And on the energy front, 5,979 heating degree days and 514 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Fenn RS 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 December-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.
