The climate verdict for Redstone
Winter sets the terms in Redstone, Montana. A pronounced 55.5°F seasonal swing and heating demand above twice the cooling total frame an annual average of 40°F. At 40/100 (moderate) the climate comfort score falls in the bottom third of the station-mapped U.S. score corpus, exceeding only 6% of scores.

Redstone'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
Summer here tops out rather than builds: the warmest normal high is 85°F around July 30, short of 90°F on every date, while 213 dates carry a normal low at or below freezing, the coldest -2°F near January 12.
The freezing stretch
The normal low stays at or below 32°F into May 4, then returns to freezing around October 5, covering 213 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 16, when 26% of years recorded at least a hundredth of an inch. The driest is February 5 at 7%. Summed across the calendar, that is about 52 wet dates a year.
The widest day
September 5 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Redstone Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 213 nights a year, placing this among the most frost-prone tenth of ranked stations.
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.
Redstone earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Redstone runs a summer-peaked wet season
49% of Redstone'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 3.1", on a wide 55.5°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, May, July, taking 52% of the annual total between them.
- Driest month: February at 0.2".
- 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.
How Redstone's precipitation splits across the calendar
About 51 days a year record measurable precipitation here, carrying 14.3" between them, or roughly 0.28 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.

Scarce-water calendar
Where Redstone's limited precipitation lands
heating led · dry · high swing
Winter and seasonal range jointly define this record. Redstone logs 9,465 heating degree days, more than twice its 265 cooling total, while the typical coldest-to-warmest-month gap reaches 55.5°F. The annual mean therefore compresses two materially different seasons.
Only about 102 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.
July and January mark the typical warm and cold ends of the calendar in this dry, high-range record. The gap is 55.5°F, so a single annual figure is especially lossy; the annual average is 40°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Redstone.
Redstone's cold-season load does not imply a wet climate. Annual precipitation is 14.3 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
