Stratton's normals sit in a dry climate class: BSk
Precipitation is low relative to temperature but above true desert thresholds: cold semi-arid steppe (BSk). Class BSk is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically cold semi-arid steppe.

The year, day by day
Stratton works both ends of the calendar. Normal highs climb to 90°F by July 16 and hold at or above 90°F on 9 dates, then normal lows drop to freezing or below on 164 dates, bottoming at 18°F around January 21.
When the heat sits
Normal highs reach 90°F from July 16 through July 24, covering 9 dates. The broader mild season, normal highs of 70°F or more, runs May 8 to October 8.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around October 30, covering 164 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 July 24, when 32% of years recorded at least a hundredth of an inch. The driest is January 1 at 10%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
September 26 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Stratton runs a summer-peaked wet season
47% of Stratton'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 3.3", on a 44.7°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: July, August, May, taking 47% of the annual total between them.
- Driest month: January at 0.4".
- Winter share: 8% 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 Stratton's precipitation splits across the calendar
About 70 days a year record measurable precipitation here, carrying 18.8" 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 Stratton
Stratton averages 33.9 inches of snowfall a year, with November 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: 33.9 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 18% 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 Stratton
heating led · dry · mid swing
Stratton's energy balance leans toward cold weather: 5,821 annual heating degree days against 901 for cooling. Its 44.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Stratton's frost-free season lasts about 156 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
-
1. Stratton coldest normal
January
The monthly mean of 30°F (-1°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.
-
2. Stratton typical freeze period
January through December
The station reports average freezing days from January through December.
-
3. Stratton snow peak
November
Stratton averages 33.9 inches of snow a year, with November the snowiest month on the normals.
