The year, day by day
Petroglyph Natl Mon works both ends of the calendar. Normal highs climb to 94°F by July 1 and hold at or above 90°F on 75 dates, then normal lows drop to freezing or below on 114 dates, bottoming at 23°F around January 1.
When the heat sits
Normal highs reach 90°F from June 8 through August 21, covering 75 dates. The broader mild season, normal highs of 70°F or more, runs April 5 to October 21.
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 6, then returns to freezing around November 14, covering 114 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 30, when 23% of years recorded at least a hundredth of an inch. The driest is May 7 at 8%. Summed across the calendar, that is about 46 wet dates a year.
The widest day
June 6 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Petroglyph Natl Mon Stands Nationally
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 75 days a year, more than four out of five ranked stations record.
Petroglyph Natl Mon earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Petroglyph Natl Mon runs a summer-peaked wet season
35% of Petroglyph 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 September at 1.6", on a 42.3°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: September, August, July, taking 48% of the annual total between them.
- Driest month: June at 0.3".
- Winter share: 16% 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.
How Petroglyph Natl Mon's precipitation splits across the calendar
About 46 days a year record measurable precipitation here, carrying 9.8" 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.

Scarce-water calendar
Where Petroglyph Natl Mon's limited precipitation lands
heating led · dry · mid swing
Petroglyph Natl Mon's energy balance leans toward cold weather: 4,065 annual heating degree days against 1,386 for cooling. Its 42.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Petroglyph Natl Mon's frost-free season lasts about 195 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 Petroglyph Natl Mon's middle-range seasonal profile. The measured spread is 42.3°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Petroglyph Natl Mon's cold-season load does not imply a wet climate. Annual precipitation is 9.8 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Petroglyph Natl Mon's primary station: PETROGLYPH NATL MON (USC00296754). 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 Petroglyph Natl Mon; 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 Petroglyph Natl Mon comes from its primary NOAA station record.
