Climate Guides
Climate Insight: Jasper, AL
An annual average temperature of 61°F, ranging from a mean daily high of 73°F to a mean daily low of 50°F is what the NOAA 1991–2020 climate normals report for Jasper, Alabama. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00014226 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Jasper sees about 61.8 inches of precipitation a year, with 0.6 inches typically falling as snow. The frost-free season averages 219 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 30 and the first fall freeze near November 4. On the energy side, 3,134 heating degree days and 1,759 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Jasper scores 73/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
