July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00445595, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Mill Gap sees about 45.3 inches of precipitation a year, with 33.7 inches typically falling as snow. The frost-free season averages 144 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 October 3. On the energy side, 6,397 heating degree days and 284 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Mill Gap scores 59/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
