The year, day by day
Monument Valley works both ends of the calendar. Normal highs climb to 93°F by July 13 and hold at or above 90°F on 57 dates, then normal lows drop to freezing or below on 102 dates, bottoming at 24°F around December 25.
When the heat sits
Normal highs reach 90°F from June 20 through August 15, covering 57 dates. The broader mild season, normal highs of 70°F or more, runs April 28 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 February 29, then returns to freezing around November 20, covering 102 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.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Data-derived climate profile
How Monument Valley's climate pattern fits together
heating led · mid swing
Monument Valley's energy balance leans toward cold weather: 4,620 annual heating degree days against 1,523 for cooling. Its 47.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Monument Valley's frost-free season lasts about 205 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 Monument Valley's middle-range seasonal profile. The measured spread is 47.4°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Monument Valley's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Monument Valley'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 Monument Valley, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Monument Valley's primary station: MONUMENT VALLEY (USC00025665). 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 Monument Valley; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Monument Valley comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
