The year, day by day
Summer here tops out rather than builds: the warmest normal high is 48°F around July 10, short of 90°F on every date, while 281 dates carry a normal low at or below freezing, the coldest -19°F near March 3.
The freezing stretch
The normal low stays at or below 32°F into June 17, then returns to freezing around September 11, covering 281 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 September 27, when 45% of years recorded at least a hundredth of an inch. The driest is January 19 at 16%. Summed across the calendar, that is about 98 wet dates a year.
The widest day
March 30 carries the biggest normal gap between afternoon and dawn, 14°F between the normal high and the normal low.

Where Barrow Post Rogers Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 281 nights a year, placing this among the most frost-prone tenth of ranked stations.
Aridity defines the water calendar: about 5 inches in a normal year lands this among the driest tenth of ranked stations.
Barrow Post Rogers earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Barrow Post Rogers runs a summer-peaked wet season
46% of Barrow Post Rogers'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 1.1", on a wide 53.6°F gap between its warmest and coldest month. 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 53% of the annual total between them.
- Driest month: January at 0.1".
- Winter share: 11% 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.
Barrow Post Rogers is dry, and what does fall arrives gently
Only about 98 days a year record measurable precipitation here, 27% of the calendar, and they carry 5.4" between them. At roughly 0.05 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 September at about 14 wet days; the driest is January at about 5.
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 Barrow Post Rogers
Barrow Post Rogers averages 45.8 inches of snowfall a year, with October the snowiest month on the normals, spread across roughly 92 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: 45.8 inches of depth.
- Days recording measurable snow: about 92 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 85% 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.

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 Barrow Post Rogers; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
