“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 Snowslip
Snowslip gets 34 inches of rain and melted snow a year. January is the wettest month and July the driest.
About 88 frost-free days a year
In half of years the last 32° night comes by June 8 and the first one by September 5. That leaves about 88 frost-free days for gardens, shorter than 99% of U.S. towns.
Heating and cooling a home in Snowslip
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Snowslip, 100% of that work is heating and 0% 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 Snowslip itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at East Glacier, MT (16 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
