The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 26, short of 90°F on every date, while 191 dates carry a normal low at or below freezing, the coldest 6°F near January 5.
The freezing stretch
The normal low stays at or below 32°F into April 21, then returns to freezing around October 14, covering 191 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 1, when 34% of years recorded at least a hundredth of an inch. The driest is November 24 at 12%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
September 5 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Maurine Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 191 nights a year, more than most ranked stations.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.

Maurine runs a summer-peaked wet season
38% of Maurine'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 May at 3.3", on a wide 54.2°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: May, June, July, taking 47% of the annual total between them.
- Driest month: January at 0.6".
- 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.
How Maurine's precipitation splits across the calendar
About 71 days a year record measurable precipitation here, carrying 19.1" between them, or roughly 0.27 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Maurine
Maurine averages 43.1 inches of snowfall a year, with April the snowiest month on the normals, spread across roughly 20 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: 43.1 inches of depth.
- Days recording measurable snow: about 20 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 23% 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 Maurine
heating led · dry · mid swing
Maurine's energy balance leans toward cold weather: 7,859 annual heating degree days against 657 for cooling. Its 54.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 138 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 Maurine; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
