The year, day by day
Winkler County works both ends of the calendar. Normal highs climb to 98°F by June 17 and hold at or above 90°F on 120 dates, then normal lows drop to freezing or below on 61 dates, bottoming at 29°F around January 1.
When the heat sits
Normal highs reach 90°F from May 16 through September 12, covering 120 dates. The broader mild season, normal highs of 70°F or more, runs March 6 to November 11.
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 4, then returns to freezing around December 6, covering 61 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 September 10, when 18% of years recorded at least a hundredth of an inch. The driest is April 16 at 7%. Summed across the calendar, that is about 45 wet dates a year.
The widest day
April 9 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Winkler County Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 120 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Winkler County earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Winkler County runs a summer-peaked wet season
37% of Winkler County'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 1.6", on a 39.8°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, May, taking 39% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 12% 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 Winkler County's precipitation splits across the calendar
About 45 days a year record measurable precipitation here, carrying 11.4" between them, or roughly 0.25 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.

Scarce-water calendar
Where Winkler County's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 11.4 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. The monthly distribution matters because the total alone does not reveal the timing.
July and January mark the typical warm and cold ends of the calendar in Winkler County's middle-range seasonal profile. The measured spread is 39.8°F. The annual average is 66°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Winkler County's normal, at 2,456 and 2,666 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 225-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.

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 Winkler County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
