What Corsicana's climate means for you
Corsicana runs 66°F a year - peaking in August, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
The NOAA 1991–2020 climate normals describe Corsicana, Texas as a location with an annual average temperature of 66°F, ranging from a mean daily high of 77°F to a mean daily low of 55°F. August is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00412019, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Corsicana averages 42.1 inches of precipitation a year, with negligible snowfall, and that matters as much to daily life here as temperature does. The frost-free season averages 247 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 14 and the first fall freeze near November 16. As for energy demand, 2,319 heating degree days and 2,595 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Corsicana scores 97/100 (Excellent), 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 August-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.
