The year, day by day

Okmulgee Wtr Wks works both ends of the calendar. Normal highs climb to 94°F by July 28 and hold at or above 90°F on 61 dates, then normal lows drop to freezing or below on 89 dates, bottoming at 26°F around January 26.

When the heat sits

Normal highs reach 90°F from June 27 through August 26, covering 61 dates. The broader mild season, normal highs of 70°F or more, runs April 5 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 26, then returns to freezing around November 30, covering 89 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.

The widest day

October 11 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Data-derived climate profile

How Okmulgee Wtr Wks's climate pattern fits together

mixed demand · mid swing

July and January mark the typical warm and cold ends of the calendar in Okmulgee Wtr Wks's middle-range seasonal profile. The measured spread is 43.7°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Okmulgee Wtr Wks's normal, at 3,599 and 1,812 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 203-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.

A moisture-range label is withheld because Okmulgee Wtr Wks's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.

These labels group NOAA 1991-2020 normals from Okmulgee Wtr Wks'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 Okmulgee Wtr Wks, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Okmulgee Wtr Wks's climate

How many days above 90°F does Okmulgee Wtr Wks get?
Okmulgee Wtr Wks averages about 67 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Okmulgee Wtr Wks?
Okmulgee Wtr Wks has 3,599 heating degree days and 1,812 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Okmulgee Wtr Wks's primary station: OKMULGEE WTR WKS (USC00346670). 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 Okmulgee Wtr Wks; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
