Guymon Muni, Oklahoma runs an annual average of 58°F, ranging from a mean daily high of 72°F to a mean daily low of 43°F, per NOAA's 1991–2020 climate normals. July is typically the warmest month of the year, while January is the coldest. Drawn from station USW00003030, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Guymon Muni receives roughly 17.8 inches of precipitation each year, predominantly as rainfall. The frost-free season averages 188 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 18 and the first fall freeze near October 23. For energy use, 4,293 heating degree days and 1,640 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Guymon Muni scores 68/100 (Good), 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, July-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.
