Rain and snow in Clarkston
Clarkston gets 17 inches of rain and melted snow a year. May is the wettest month and July the driest. Rain or snow falls on about 62 days a year.
About 160 frost-free days a year
In half of years the last 32° night comes by May 3 and the first one by October 12. That leaves about 160 frost-free days for gardens, shorter than 71% of U.S. towns.
Heating and cooling a home in Clarkston
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Clarkston, 90% of that work is heating and 10% 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 Clarkston itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Plymouth, UT (6 mi, snow) and Cutler Dam, UT (6 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
