The year, day by day
Alamogordo works both ends of the calendar. Normal highs climb to 95°F by June 21 and hold at or above 90°F on 94 dates, then normal lows drop to freezing or below on 20 dates, bottoming at 32°F around December 23.
When the heat sits
Normal highs reach 90°F from May 30 through August 31, covering 94 dates. The broader mild season, normal highs of 70°F or more, runs March 25 to October 31.
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 5, then returns to freezing around December 17, covering 20 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 29, when 33% of years recorded at least a hundredth of an inch. The driest is April 26 at 7%. Summed across the calendar, that is about 56 wet dates a year.
The widest day
June 1 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Where Alamogordo Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 94 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.
Alamogordo earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Alamogordo runs a summer-peaked wet season
39% of Alamogordo'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 August at 2.0", on a 37.9°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: August, July, September, taking 48% of the annual total between them.
- Driest month: April at 0.3".
- Winter share: 22% 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.
Alamogordo is dry, and what does fall arrives gently
Only about 56 days a year record measurable precipitation here, 15% of the calendar, and they carry 10.6" between them. At roughly 0.19 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is July at about 9 wet days; the driest is April at about 2.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.
Snow reaches Alamogordo, but rarely amounts to much
The normals record 2.4 inches of snow a year here, most likely in January. 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 1 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.

Scarce-water calendar
Where Alamogordo's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 10.6 inches annually, within PlainClimate's dry band. Annual snowfall totals 2.4 inches. The monthly distribution matters because the total alone does not reveal the timing.
July and December mark the typical warm and cold ends of the calendar in Alamogordo's middle-range seasonal profile. The measured spread is 37.9°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Alamogordo's normal, at 2,700 and 2,036 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.
Alamogordo has a long frost-free window of roughly 254 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
