The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 4, short of 90°F on every date, while 198 dates carry a normal low at or below freezing, the coldest 13°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 28, then returns to freezing around October 14, covering 198 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 37% of years recorded at least a hundredth of an inch. The driest is June 6 at 10%. Summed across the calendar, that is about 73 wet dates a year.
The widest day
June 7 carries the biggest normal gap between afternoon and dawn, 42°F between the normal high and the normal low.

Where Gallup Muni Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 198 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Gallup Muni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Gallup Muni runs a summer-peaked wet season
37% of Gallup Muni'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 August at 1.9", on a 42.2°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: August, July, September, taking 45% of the annual total between them.
- Driest month: June at 0.4".
- Winter share: 21% 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.
Gallup Muni is dry, and what does fall arrives gently
Only about 72 days a year record measurable precipitation here, 20% of the calendar, and they carry 10.7" between them. At roughly 0.15 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 11 wet days; the driest is June at about 3.
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 Gallup Muni
Gallup Muni averages 33.8 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 23 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: 33.8 inches of depth.
- Days recording measurable snow: about 23 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 32% of the year's precipitation.

Snow and freeze rhythm
When cold and snow define Gallup Muni
heating led · dry · mid swing
Gallup Muni's energy balance leans toward cold weather: 6,105 annual heating degree days against 475 for cooling. Its 42.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 120 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
-
1. Gallup Muni coldest normal
December
The monthly mean of 30°F (-1°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Gallup Muni typical freeze period
January through December
The station reports average freezing days from January through December.

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 Gallup Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
