The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 21, short of 90°F on every date, while 182 dates carry a normal low at or below freezing, the coldest 1°F near January 19.
The freezing stretch
The normal low stays at or below 32°F into April 19, then returns to freezing around October 21, covering 182 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 14, when 27% of years recorded at least a hundredth of an inch. The driest is November 21 at 9%. Summed across the calendar, that is about 63 wet dates a year.
The widest day
September 10 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Rauville Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 182 nights a year, more than most ranked stations.

Rauville runs a summer-peaked wet season
40% of Rauville'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 July at 3.6", on a wide 59.3°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: July, June, September, taking 41% of the annual total between them.
- Driest month: January at 0.7".
- 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 Rauville, it arrives in quantity
23.4" of precipitation falls across only about 63 wet days here, averaging 0.37 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 63 a year, 17% of all days
- Average depth per wet day
- 0.37 inches
- Most wet days
- June, about 8
- Fewest wet days
- November, about 2
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 Rauville
Rauville averages 31.8 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 15 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: 31.8 inches of depth.
- Days recording measurable snow: about 15 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 Rauville
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Rauville logs 8,563 heating degree days, more than twice its 466 cooling total, while the typical coldest-to-warmest-month gap reaches 59.3°F. The annual mean therefore compresses two materially different seasons.
Only about 144 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.

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