The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 24, short of 90°F on every date, while 193 dates carry a normal low at or below freezing, the coldest 14°F near February 1.
The freezing stretch
The normal low stays at or below 32°F into April 26, then returns to freezing around October 17, covering 193 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 May 8, when 40% of years recorded at least a hundredth of an inch. The driest is November 28 at 19%. Summed across the calendar, that is about 100 wet dates a year.
The widest day
August 27 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Gillette Campbell Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 193 nights a year, more than most ranked stations.
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.
Gillette Campbell earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Gillette Campbell spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 8%, with neither reaching the 35% that would mark a distinct wet season. Gillette Campbell has no dry season to plan around, though it does carry a wide 46.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.6" and January 0.3". The three wettest months together take 46% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Gillette Campbell is dry, and what does fall arrives gently
Only about 100 days a year record measurable precipitation here, 27% of the calendar, and they carry 13.6" between them. At roughly 0.14 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is May at about 12 wet days; the driest is November at about 6.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Gillette Campbell's limited precipitation lands
heating led · dry · mid swing
Gillette Campbell's energy balance leans toward cold weather: 7,497 annual heating degree days against 519 for cooling. Its 46.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 126 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 Gillette Campbell's middle-range seasonal profile. The measured spread is 46.1°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Gillette Campbell's cold-season load does not imply a wet climate. Annual precipitation is 13.6 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.

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