The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 27, short of 90°F on every date, while 191 dates carry a normal low at or below freezing, the coldest 18°F near December 26.
The freezing stretch
The normal low stays at or below 32°F into April 23, then returns to freezing around October 16, 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 December 26, when 30% of years recorded at least a hundredth of an inch. The driest is August 13 at 8%. Summed across the calendar, that is about 76 wet dates a year.
The widest day
July 31 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Wilbur 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.
A drier-than-most normal water year — around 13 inches, below what four out of five ranked stations collect.
Wilbur earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Wilbur spreads its precipitation across the year
Neither half of the year dominates here: June through August take 15% of the annual total and December through February 34%, with neither reaching the 35% that would mark a distinct wet season. Wilbur has no dry season to plan around, though it does carry a 41.8°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 1.7" and August 0.3". The three wettest months together take 39% 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.
Wilbur is dry, and what does fall arrives gently
Only about 74 days a year record measurable precipitation here, 20% of the calendar, and they carry 12.5" between them. At roughly 0.17 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 December at about 9 wet days; the driest is August at about 3.
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 Wilbur's limited precipitation lands
heating led · dry · mid swing
Wilbur's energy balance leans toward cold weather: 7,346 annual heating degree days against 293 for cooling. Its 41.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 113 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 Wilbur's middle-range seasonal profile. The measured spread is 41.8°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Wilbur's cold-season load does not imply a wet climate. Annual precipitation is 12.5 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.
