The year, day by day
Chaco Canyon Natl Mon works both ends of the calendar. Normal highs climb to 90°F by July 4 and hold at or above 90°F on 16 dates, then normal lows drop to freezing or below on 196 dates, bottoming at 11°F around January 1.
When the heat sits
Normal highs reach 90°F from July 1 through July 16, covering 16 dates. The broader mild season, normal highs of 70°F or more, runs May 1 to October 10.
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 April 25, then returns to freezing around October 13, covering 196 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 30% of years recorded at least a hundredth of an inch. The driest is June 9 at 11%. Summed across the calendar, that is about 60 wet dates a year.
The widest day
June 7 carries the biggest normal gap between afternoon and dawn, 41°F between the normal high and the normal low.

Where Chaco Canyon Natl Mon Stands Nationally
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 41°F, sharper than nine in ten ranked stations see.

Chaco Canyon Natl Mon runs a summer-peaked wet season
35% of Chaco Canyon Natl Mon'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 July at 1.4", on a 44.6°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: July, August, September, taking 43% of the annual total between them.
- Driest month: June at 0.4".
- Winter share: 20% 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.
Chaco Canyon Natl Mon is dry, and what does fall arrives gently
Only about 60 days a year record measurable precipitation here, 16% of the calendar, and they carry 8.9" between them. At roughly 0.15 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 August at about 9 wet days; the driest is June at about 3.
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 Chaco Canyon Natl Mon, but rarely amounts to much
The normals record 11.2 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 9 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 Chaco Canyon Natl Mon's limited precipitation lands
heating led · dry · mid swing
Chaco Canyon Natl Mon's energy balance leans toward cold weather: 6,230 annual heating degree days against 531 for cooling. Its 44.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 122 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Chaco Canyon Natl Mon's middle-range seasonal profile. The measured spread is 44.6°F. The annual average is 49°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Chaco Canyon Natl Mon's cold-season load does not imply a wet climate. Annual precipitation is 8.9 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 11.2 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

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 Chaco Canyon Natl Mon; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
