The frost-free season averages 302 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 20 and the first fall freeze near December 19. On the energy side, 1,424 heating degree days and 2,690 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Sapelo IS scores 100/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
