“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Granite
Granite gets 29 inches of rain and melted snow a year. January is the wettest month and July the driest. Rain or snow falls on about 97 days a year.
About 138 frost-free days a year
In half of years the last 32° night comes by May 17 and the first one by October 5. That leaves about 138 frost-free days for gardens, shorter than 90% of U.S. towns.
Heating and cooling a home in Granite
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Granite, 96% of that work is heating and 4% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
Granite and its neighbors
Granite borders 2 towns with climate data. January nights across them vary by 2.9°. Sandy has both the coldest January nights (22°) and the hottest July afternoons (91°). Granite’s January low is 19° and its July high 83°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Granite compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Granite averaged 1.7° warmer than the 1900s. The biggest change is in March (+3.3°). The shift is larger than in 82% of U.S. towns.

How much a month can swing
A normal is an average, and real years wander around it. November swings the most: between 1991 and 2020 its average temperature ranged from 27° to 42°. September is the most reliable, staying within 9°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Granite itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Holladay 0.5 Ese, UT (6 mi, snow) and Sundance, UT (17 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
