The year, day by day
Tatum works both ends of the calendar. Normal highs climb to 93°F by June 19 and hold at or above 90°F on 86 dates, then normal lows drop to freezing or below on 123 dates, bottoming at 23°F around January 5.
When the heat sits
Normal highs reach 90°F from June 3 through August 27, covering 86 dates. The broader mild season, normal highs of 70°F or more, runs March 26 to October 30.
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 13, then returns to freezing around November 12, covering 123 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 July 16, when 20% of years recorded at least a hundredth of an inch. The driest is January 7 at 7%. Summed across the calendar, that is about 47 wet dates a year.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Tatum Stands Nationally
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 36°F, sharper than nine in ten ranked stations see.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 86 days a year, more than four out of five ranked stations record.

Tatum runs a summer-peaked wet season
40% of Tatum'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 September at 2.5", on a 39.1°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: September, July, August, taking 45% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 9% 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.
How Tatum's precipitation splits across the calendar
About 48 days a year record measurable precipitation here, carrying 15.2" between them, or roughly 0.32 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Snow reaches Tatum, but rarely amounts to much
The normals record 6.1 inches of snow a year here, most likely in December. 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 Tatum's climate pattern fits together
heating led · dry · mid swing
Tatum's energy balance leans toward cold weather: 3,756 annual heating degree days against 1,457 for cooling. Its 39.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Tatum's frost-free season lasts about 190 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 Tatum's middle-range seasonal profile. The measured spread is 39.1°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Tatum's cold-season load does not imply a wet climate. Annual precipitation is 15.2 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 6.1 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Tatum'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 Tatum, not an official NOAA class or a year-ahead forecast.
