The year, day by day
Spavinaw works both ends of the calendar. Normal highs climb to 92°F by July 28 and hold at or above 90°F on 47 dates, then normal lows drop to freezing or below on 78 dates, bottoming at 26°F around January 14.
When the heat sits
Normal highs reach 90°F from July 7 through August 22, covering 47 dates. The broader mild season, normal highs of 70°F or more, runs April 13 to October 23.
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 23, then returns to freezing around December 8, covering 78 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 5, when 33% of years recorded at least a hundredth of an inch. The driest is January 20 at 18%. Summed across the calendar, that is about 89 wet dates a year.
The widest day
March 26 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Spavinaw spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 15%, with neither reaching the 35% that would mark a distinct wet season. Spavinaw has no dry season to plan around, though it does carry a 43.9°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 6.3" and January 2.3". The three wettest months together take 34% 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 Spavinaw, it arrives in quantity
46.6" of precipitation falls across only about 88 wet days here, averaging 0.53 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 88 a year, 24% of all days
- Average depth per wet day
- 0.53 inches
- Most wet days
- May, about 10
- 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 Spavinaw, but rarely amounts to much
The normals record 5.5 inches of snow a year here, most likely in March. 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 2 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 Spavinaw's climate pattern fits together
heating led · wet · mid swing
Spavinaw's energy balance leans toward cold weather: 3,685 annual heating degree days against 1,816 for cooling. Its 43.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Spavinaw's frost-free season lasts about 209 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 Spavinaw's middle-range seasonal profile. The measured spread is 43.9°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Spavinaw carries 46.6 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 5.5 inches. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Spavinaw'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 Spavinaw, not an official NOAA class or a year-ahead forecast.
