These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
FT Thomas, Arizona runs an annual average of 65°F, ranging from a mean daily high of 82°F to a mean daily low of 47°F, per NOAA's 1991–2020 climate normals. July is typically the warmest month of the year, while December is the coldest. Drawn from station USC00023150, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Beyond temperature, FT Thomas averages 10.2 inches of precipitation annually, predominantly as rainfall - a real factor for anyone planning to live, garden, or travel here. 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 April 1 and the first fall freeze near November 6. Turning to energy use, 2,592 heating degree days and 2,431 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, FT Thomas scores 78/100 (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 July-driven heat, or deep winter for December-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.
