The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 27, short of 90°F on every date, while 170 dates carry a normal low at or below freezing, the coldest 14°F near December 25.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around October 24, covering 170 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.
The widest day
August 17 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Where Rigby Stands Nationally
A drier-than-most normal water year — around 14 inches, below what four out of five ranked stations collect.
Rigby earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Rigby spreads its precipitation across the year
Neither half of the year dominates here: June through August take 20% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Rigby has no dry season to plan around, though it does carry a wide 46.7°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 1.8" and July 0.6". The three wettest months together take 34% 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.

Scarce-water calendar
Where Rigby's limited precipitation lands
heating led · dry · mid swing
Rigby's energy balance leans toward cold weather: 7,311 annual heating degree days against 383 for cooling. Its 46.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 149 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 Rigby's middle-range seasonal profile. The measured spread is 46.7°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Rigby's cold-season load does not imply a wet climate. Annual precipitation is 13.5 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.
