The year, day by day
Aztec Ruins National Monument works both ends of the calendar. Normal highs climb to 94°F by July 9 and hold at or above 90°F on 73 dates, then normal lows drop to freezing or below on 171 dates, bottoming at 16°F around January 1.
When the heat sits
Normal highs reach 90°F from June 14 through August 25, covering 73 dates. The broader mild season, normal highs of 70°F or more, runs April 13 to October 19.
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 13, then returns to freezing around October 26, covering 171 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 August 19, when 22% of years recorded at least a hundredth of an inch. The driest is June 15 at 8%. Summed across the calendar, that is about 57 wet dates a year.
The widest day
June 8 carries the biggest normal gap between afternoon and dawn, 41°F between the normal high and the normal low.

Where Aztec Ruins National Monument Stands Nationally
Aridity defines the water calendar: about 10 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.
Aztec Ruins National Monument earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Aztec Ruins National Monument spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Aztec Ruins National Monument has no dry season to plan around, though it does carry a 44.5°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 1.3" and June 0.3". The three wettest months together take 34% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Aztec Ruins National Monument is dry, and what does fall arrives gently
Only about 57 days a year record measurable precipitation here, 15% of the calendar, and they carry 10.1" between them. At roughly 0.18 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 7 wet days; the driest is June 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 Aztec Ruins National Monument, but rarely amounts to much
The normals record 10.9 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 7 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.

Where Aztec Ruins National Monument's limited precipitation lands
heating led · dry · mid swing
Aztec Ruins National Monument's energy balance leans toward cold weather: 5,163 annual heating degree days against 914 for cooling. Its 44.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 147 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 Aztec Ruins National Monument's middle-range seasonal profile. The measured spread is 44.5°F. The annual average is 53°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Aztec Ruins National Monument's cold-season load does not imply a wet climate. Annual precipitation is 10.1 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 10.9 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 Aztec Ruins National Monument; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
