The year, day by day
Chiricahua National Monument works both ends of the calendar. Normal highs climb to 93°F by June 23 and hold at or above 90°F on 41 dates, then normal lows drop to freezing or below on 70 dates, bottoming at 30°F around January 1.
When the heat sits
Normal highs reach 90°F from June 7 through July 17, covering 41 dates. The broader mild season, normal highs of 70°F or more, runs March 31 to November 7.
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 11, then returns to freezing around December 4, covering 70 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 28, when 46% of years recorded at least a hundredth of an inch. The driest is April 28 at 6%. Summed across the calendar, that is about 69 wet dates a year.
The widest day
June 14 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Chiricahua National Monument runs a summer-peaked wet season
49% of Chiricahua National Monument'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 4.6", on a 32°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 53% 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.
How Chiricahua National Monument's precipitation splits across the calendar
About 69 days a year record measurable precipitation here, carrying 18.7" 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.
Snow reaches Chiricahua National Monument, but rarely amounts to much
The normals record 3.7 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 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 Chiricahua National Monument's climate pattern fits together
heating led · dry · mid swing
Chiricahua National Monument's energy balance leans toward cold weather: 3,138 annual heating degree days against 1,149 for cooling. Its 32.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Chiricahua National Monument's frost-free season lasts about 206 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 Chiricahua National Monument's middle-range seasonal profile. The measured spread is 32.0°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Chiricahua National Monument's cold-season load does not imply a wet climate. Annual precipitation is 18.7 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 3.7 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Chiricahua National Monument'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 Chiricahua National Monument, not an official NOAA class or a year-ahead forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Chiricahua National Monument's primary station: CHIRICAHUA NM (USC00021664). For informational purposes only.
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 Chiricahua National Monument; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
