The year, day by day
Bartlesville works both ends of the calendar. Normal highs climb to 94°F by July 27 and hold at or above 90°F on 65 dates, then normal lows drop to freezing or below on 112 dates, bottoming at 21°F around January 10.
When the heat sits
Normal highs reach 90°F from June 26 through August 29, covering 65 dates. The broader mild season, normal highs of 70°F or more, runs April 10 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 March 9, then returns to freezing around November 19, covering 112 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 12, when 35% of years recorded at least a hundredth of an inch. The driest is January 10 at 17%. Summed across the calendar, that is about 91 wet dates a year.
The widest day
October 29 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Bartlesville Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 65 days a year, more than four out of five ranked stations record.

Bartlesville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Bartlesville has no dry season to plan around, though it does carry a wide 46.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 5.3" and February 1.9". 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 Bartlesville, it arrives in quantity
39.7" of precipitation falls across only about 90 wet days here, averaging 0.44 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 90 a year, 25% of all days
- Average depth per wet day

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 Bartlesville's climate pattern fits together
heating led · moderate · mid swing
Bartlesville's energy balance leans toward cold weather: 4,193 annual heating degree days against 1,673 for cooling. Its 46.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Bartlesville's frost-free season lasts about 196 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Bartlesville's middle-range seasonal profile. The measured spread is 46.1°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Bartlesville's 39.7 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 Bartlesville's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Bartlesville, not an official NOAA class or a year-ahead forecast.
