The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 6, short of 90°F on every date, while 139 dates carry a normal low at or below freezing, the coldest 21°F near January 20.
The freezing stretch
The normal low stays at or below 32°F into March 28, then returns to freezing around November 11, covering 139 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
April 17 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Grantsville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Grantsville has no dry season to plan around, though it does carry a 42.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.6" and November 3.1". The three wettest months together take 33% 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.

Data-derived climate profile
How Grantsville's climate pattern fits together
heating led · wet · mid swing
Grantsville's energy balance leans toward cold weather: 5,062 annual heating degree days against 947 for cooling. Its 42.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Grantsville's frost-free season lasts about 177 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Grantsville's middle-range seasonal profile. The measured spread is 42.8°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Grantsville carries 49.7 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Grantsville's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Grantsville, not an official NOAA class or a year-ahead forecast.
