Climate Insight: Clayton, AL
An annual average temperature of 65°F, ranging from a mean daily high of 76°F to a mean daily low of 55°F is what the NOAA 1991–2020 climate normals report for Clayton, Alabama. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00011725 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Beyond temperature, Clayton averages 55.6 inches of precipitation annually, with negligible snowfall - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 253 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 11 and the first fall freeze near November 19. Turning to energy use, 2,117 heating degree days and 2,264 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Clayton scores 87/100 (Excellent), 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.
