The year, day by day
Navajo Dam works both ends of the calendar. Normal highs climb to 93°F by July 15 and hold at or above 90°F on 49 dates, then normal lows drop to freezing or below on 142 dates, bottoming at 21°F around December 22.
When the heat sits
Normal highs reach 90°F from June 24 through August 11, covering 49 dates. The broader mild season, normal highs of 70°F or more, runs April 29 to October 13.
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 28, then returns to freezing around November 8, covering 142 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 26, when 25% of years recorded at least a hundredth of an inch. The driest is June 10 at 9%. Summed across the calendar, that is about 59 wet dates a year.
The widest day
June 14 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Navajo Dam Stands Nationally
A drier-than-most normal water year — around 12 inches, below what four out of five ranked stations collect.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.

Navajo Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Navajo Dam has no dry season to plan around, though it does carry a wide 45.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: July averages 1.7" and June 0.4". 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.
How Navajo Dam's precipitation splits across the calendar
About 59 days a year record measurable precipitation here, carrying 12.1" between them, or roughly 0.21 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 Navajo Dam, but rarely amounts to much
The normals record 7.7 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 6 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 Navajo Dam's limited precipitation lands
heating led · dry · mid swing
Navajo Dam's energy balance leans toward cold weather: 5,214 annual heating degree days against 1,001 for cooling. Its 45.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Navajo Dam's frost-free season lasts about 175 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Navajo Dam's middle-range seasonal profile. The measured spread is 45.2°F. The annual average is 53°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Navajo Dam's cold-season load does not imply a wet climate. Annual precipitation is 12.1 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 7.7 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
