Climate Guides
Climate Insight: Hamilton, AL
Based on station USC00013645 feeding NOAA's 1991–2020 climate normals, Hamilton, Alabama averages 61°F a year, ranging from a mean daily high of 74°F to a mean daily low of 48°F. July is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Beyond temperature, Hamilton averages 61.7 inches of precipitation annually, with 1.3 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 199 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 11 and the first fall freeze near October 27. Turning to energy use, 3,303 heating degree days and 1,781 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Hamilton scores 73/100 (Good), 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 January-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.
