The year, day by day

Canyon De Chelly works both ends of the calendar. Normal highs climb to 94°F by July 8 and hold at or above 90°F on 62 dates, then normal lows drop to freezing or below on 153 dates, bottoming at 18°F around January 1.

When the heat sits

Normal highs reach 90°F from June 14 through August 14, covering 62 dates. The broader mild season, normal highs of 70°F or more, runs April 21 to October 15.

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 March 31, then returns to freezing around October 31, covering 153 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 1, when 24% of years recorded at least a hundredth of an inch. The driest is June 8 at 7%. Summed across the calendar, that is about 52 wet dates a year.

The widest day

June 9 carries the biggest normal gap between afternoon and dawn, 38°F between the normal high and the normal low.

Where Canyon De Chelly 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 38°F, sharper than nine in ten ranked stations see.

Canyon De Chelly spreads its precipitation across the year

Neither half of the year dominates here: June through August take 30% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Canyon De Chelly has no dry season to plan around, though it does carry a wide 45.1°F gap between its warmest and coldest month.

The gap between the wettest and driest month still matters: August averages 1.3" and June 0.3". The three wettest months together take 37% 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.

Canyon De Chelly is dry, and what does fall arrives gently

Only about 52 days a year record measurable precipitation here, 14% of the calendar, and they carry 8.8" between them. At roughly 0.17 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 Canyon De Chelly, but rarely amounts to much

The normals record 4.9 inches of snow a year here, most likely in December. 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 4 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 Canyon De Chelly's limited precipitation lands

heating led · dry · mid swing

Canyon De Chelly's energy balance leans toward cold weather: 5,162 annual heating degree days against 985 for cooling. Its 45.1°F seasonal range still makes the monthly rows more useful than the annual average alone.

Canyon De Chelly's frost-free season lasts about 155 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 Canyon De Chelly's middle-range seasonal profile. The measured spread is 45.1°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Canyon De Chelly's cold-season load does not imply a wet climate. Annual precipitation is 8.8 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 4.9 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Questions about Canyon De Chelly's climate

How dry is Canyon De Chelly?
Canyon De Chelly receives 8.8 inches of precipitation a year, spread across roughly 52 days that record any measurable amount. For reference, the contiguous United States averages near 30 inches. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Canyon De Chelly get?
Canyon De Chelly averages about 72 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Canyon De Chelly?
Canyon De Chelly has 5,162 heating degree days and 985 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Canyon De Chelly's primary station: CANYON DE CHELLY (USC00021248). 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 Canyon De Chelly; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
