“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 La Sal
La Sal gets 14 inches of rain and melted snow a year. July is the wettest month and June the driest. Rain or snow falls on about 66 days a year. Snow covers the ground about 59 days of the year.
About 141 frost-free days a year
In half of years the last 32° night comes by May 17 and the first one by October 6. That leaves about 141 frost-free days for gardens, shorter than 88% of U.S. towns.
Heating and cooling a home in La Sal
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In La Sal, 93% of that work is heating and 7% 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for La Sal itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at La Sal 1sw, UT (1 mi) away. Normals are 30-year averages, not a forecast.
