Climate Insight: Chisos Basin, TX

The NOAA 1991–2020 climate normals describe Chisos Basin, Texas as a location with an annual average temperature of 63°F, ranging from a mean daily high of 74°F to a mean daily low of 52°F. June is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00411715, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Chisos Basin receives roughly 18.3 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near March 10 and the first fall freeze near November 19. For energy use, 2,198 heating degree days and 1,456 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Chisos Basin scores 77/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for June-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
