The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 10, short of 90°F on every date, while 168 dates carry a normal low at or below freezing, the coldest 3°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into April 11, then returns to freezing around October 27, covering 168 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 June 9, when 37% of years recorded at least a hundredth of an inch. The driest is November 11 at 19%. Summed across the calendar, that is about 92 wet dates a year.
The widest day
September 30 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Theilman runs a summer-peaked wet season
40% of Theilman'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 June at 5.3", on a wide 57.4°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: June, August, May, taking 40% of the annual total between them.
- Driest month: January at 1.0".
- Winter share: 9% 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.
When it rains in Theilman, it arrives in quantity
35.5" of precipitation falls across only about 92 wet days here, averaging 0.39 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 92 a year, 25% of all days
- Average depth per wet day
- 0.39 inches
- Most wet days
- June, about 11
- Fewest wet days
- February, about 6
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Winter brings real snow to Theilman
Theilman averages 48.3 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 21 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: 48.3 inches of depth.
- Days recording measurable snow: about 21 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 14% 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 Theilman
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Theilman logs 7,860 heating degree days, more than twice its 614 cooling total, while the typical coldest-to-warmest-month gap reaches 57.4°F. The annual mean therefore compresses two materially different seasons.
Only about 148 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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Theilman's primary station: THEILMAN 1SSW (USC00218227). 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 Theilman; 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 Theilman comes from its primary NOAA station record.
