The year, day by day
Brigham City works both ends of the calendar. Normal highs climb to 92°F by July 24 and hold at or above 90°F on 24 dates, then normal lows drop to freezing or below on 173 dates, bottoming at 14°F around December 27.
When the heat sits
Normal highs reach 90°F from July 14 through August 6, covering 24 dates. The broader mild season, normal highs of 70°F or more, runs May 25 to September 27.
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 21, covering 173 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 January 19, when 33% of years recorded at least a hundredth of an inch. The driest is July 12 at 9%. Summed across the calendar, that is about 84 wet dates a year.
The widest day
August 20 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Brigham City 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 27%, with neither reaching the 35% that would mark a distinct wet season. Brigham City has no dry season to plan around, though it does carry a wide 49.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.8" and July 0.3". The three wettest months together take 35% 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.
Brigham City is dry, and what does fall arrives gently
Only about 84 days a year record measurable precipitation here, 23% of the calendar, and they carry 13.8" between them. At roughly 0.16 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 10 wet days; the driest is July 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 Brigham City's limited precipitation lands
heating led · dry · mid swing
Brigham City's energy balance leans toward cold weather: 7,093 annual heating degree days against 617 for cooling. Its 49.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 146 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 Brigham City's middle-range seasonal profile. The measured spread is 49.9°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Brigham City's cold-season load does not imply a wet climate. Annual precipitation is 13.8 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.
