The year, day by day
Monahans works both ends of the calendar. Normal highs climb to 97°F by June 20 and hold at or above 90°F on 114 dates, then normal lows drop to freezing or below on 25 dates, bottoming at 31°F around January 1.
When the heat sits
Normal highs reach 90°F from May 19 through September 9, covering 114 dates. The broader mild season, normal highs of 70°F or more, runs March 7 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 January 13, then returns to freezing around December 20, covering 25 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 1, when 22% of years recorded at least a hundredth of an inch. The driest is December 18 at 8%. Summed across the calendar, that is about 50 wet dates a year.
The widest day
April 2 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Where Monahans Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 114 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Monahans earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Monahans runs a summer-peaked wet season
41% of Monahans'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 2.1", on a 37.5°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, August, July, taking 45% 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 Monahans's precipitation splits across the calendar
About 50 days a year record measurable precipitation here, carrying 13.4" between them, or roughly 0.27 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 Monahans's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 13.4 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 Monahans's middle-range seasonal profile. The measured spread is 37.5°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 Monahans's normal, at 2,290 and 2,597 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.
Monahans has a long frost-free window of roughly 240 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
