Chandler, OK Climate

Climate Insight: Chandler, OK

An annual average temperature of 61°F, ranging from a mean daily high of 72°F to a mean daily low of 50°F is what the NOAA 1991–2020 climate normals report for Chandler, Oklahoma. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00341685 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Chandler receives roughly an uncharted amount of precipitation each year, predominantly as rainfall. The frost-free season averages 214 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 2 and the first fall freeze near November 2. For energy use, 3,464 heating degree days and 1,932 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Chandler 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.
