Climate Insight: Armstrong, TX
Based on station USC00410345 feeding NOAA's 1991–2020 climate normals, Armstrong, Texas averages 73°F a year, ranging from a mean daily high of 85°F to a mean daily low of 61°F. August 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.
Anyone planning to live, garden, or travel in Armstrong should weigh precipitation alongside temperature: the annual average runs 28.1 inches, predominantly as rainfall. The frost-free season averages 286 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 22 and the first fall freeze near December 5. And on the energy front, 853 heating degree days and 3,861 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Armstrong scores 92/100 (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, August-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.
