Frederick, OK Climate

Climate Insight: Frederick, OK

Based on station USC00343353 feeding NOAA's 1991–2020 climate normals, Frederick, Oklahoma averages 62°F a year, ranging from a mean daily high of 75°F to a mean daily low of 49°F. July 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.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Frederick sees about an uncharted amount of precipitation a year, predominantly as rainfall. The frost-free season averages 215 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 3 and the first fall freeze near November 4. On the energy side, 3,267 heating degree days and 2,245 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Frederick scores 73/100 (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.
