The year, day by day
Oklahoma City Post works both ends of the calendar. Normal highs climb to 96°F by July 25 and hold at or above 90°F on 73 dates, then normal lows drop to freezing or below on 74 dates, bottoming at 28°F around January 8.
When the heat sits
Normal highs reach 90°F from June 20 through August 31, covering 73 dates. The broader mild season, normal highs of 70°F or more, runs April 6 to October 26.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into February 18, then returns to freezing around December 7, covering 74 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is May 23, when 29% of years recorded at least a hundredth of an inch. The driest is January 6 at 12%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
March 26 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Oklahoma City Post Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 73 days a year, more than four out of five ranked stations record.
Oklahoma City Post earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Oklahoma City Post runs a summer-peaked wet season
36% of Oklahoma City Post's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 4.8", on a 44.8°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, May, August, taking 41% of the annual total between them.
- Driest month: January at 0.8".
- Winter share: 10% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Oklahoma City Post, it arrives in quantity
30.7" of precipitation falls across only about 73 wet days here, averaging 0.42 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 73 a year, 20% of all days
- Average depth per wet day
- 0.42 inches

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Oklahoma City Post's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Oklahoma City Post's middle-range seasonal profile. The measured spread is 44.8°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Oklahoma City Post's normal, at 3,432 and 2,167 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 216-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
Oklahoma City Post's 30.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Oklahoma City Post's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Oklahoma City Post, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Oklahoma City Post's primary station: OKLAHOMA CITY POST AP (USW00003954). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Oklahoma City Post; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Oklahoma City Post comes from its primary NOAA station record.
