The year, day by day
Tulsa works both ends of the calendar. Normal highs climb to 95°F by July 31 and hold at or above 90°F on 71 dates, then normal lows drop to freezing or below on 68 dates, bottoming at 28°F around January 14.
When the heat sits
Normal highs reach 90°F from June 22 through August 31, covering 71 dates. The broader mild season, normal highs of 70°F or more, runs April 7 to October 25.
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 16, then returns to freezing around December 11, covering 68 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 15, when 36% of years recorded at least a hundredth of an inch. The driest is January 20 at 19%. Summed across the calendar, that is about 95 wet dates a year.
The widest day
April 3 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Tulsa Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 71 days a year, more than four out of five ranked stations record.

Tulsa spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 14%, with neither reaching the 35% that would mark a distinct wet season. Tulsa has no dry season to plan around, though it does carry a 44.9°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.7" and February 1.6". The three wettest months together take 36% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Tulsa, it arrives in quantity
41.0" of precipitation falls across only about 94 wet days here, averaging 0.43 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 94 a year, 26% of all days
- Average depth per wet day
- 0.43 inches
- Most wet days
- May, about 11
- Fewest wet days
- January, about 6
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.
Snow reaches Tulsa, but rarely amounts to much
The normals record 8.7 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 5 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Tulsa's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Tulsa's middle-range seasonal profile. The measured spread is 44.9°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 Tulsa's normal, at 3,451 and 2,128 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 218-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.
Tulsa's 41.0 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 8.7 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Tulsa'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 Tulsa, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
