“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 Genesee
Genesee gets 19 inches of rain and melted snow a year. April is the wettest month and January the driest. Rain or snow falls on about 104 days a year. Snow covers the ground about 92 days of the year.
About 118 frost-free days a year
In half of years the last 32° night comes by May 23 and the first one by September 22. That leaves about 118 frost-free days for gardens, shorter than 98% of U.S. towns.
Heating and cooling a home in Genesee
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Genesee, 99% of that work is heating and 1% 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 Genesee itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Golden 3sw, CO (3 mi, snow) and Evergreen, CO (4 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
