The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 14, short of 90°F on every date, while 144 dates carry a normal low at or below freezing, the coldest 19°F near December 26.
The freezing stretch
The normal low stays at or below 32°F into March 29, then returns to freezing around November 7, covering 144 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 29, when 29% of years recorded at least a hundredth of an inch. The driest is June 14 at 9%. Summed across the calendar, that is about 65 wet dates a year.
The widest day
June 20 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Natural Bridges 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 26%, with neither reaching the 35% that would mark a distinct wet season. Natural Bridges National Monument has no dry season to plan around, though it does carry a 44.8°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 1.6" and June 0.4". The three wettest months together take 35% 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.
Natural Bridges National Monument is dry, and what does fall arrives gently
Only about 65 days a year record measurable precipitation here, 18% of the calendar, and they carry 12.0" between them. At roughly 0.19 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 8 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.
Winter brings real snow to Natural Bridges National Monument
Natural Bridges National Monument averages 32.0 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 16 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 32.0 inches of depth.
- Days recording measurable snow: about 16 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 27% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Natural Bridges National Monument
heating led · dry · mid swing
Natural Bridges National Monument's energy balance leans toward cold weather: 5,925 annual heating degree days against 751 for cooling. Its 44.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Natural Bridges National Monument's frost-free season lasts about 161 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

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 Natural Bridges National Monument; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
