“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 Sandy
Sandy gets 20 inches of rain and melted snow a year. April is the wettest month and July the driest. Rain or snow falls on about 89 days a year.
About 174 frost-free days a year
In half of years the last 32° night comes by April 29 and the first one by October 22. That leaves about 174 frost-free days for gardens, shorter than 56% of U.S. towns.
Heating and cooling a home in Sandy
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Sandy, 82% of that work is heating and 18% 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.

Snow, frost dates and day counts come from NOAA’s weather station at Cottonwood Weir, UT (5 mi) away. Normals are 30-year averages, not a forecast.
