“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 Shoshone
Shoshone gets 10 inches of rain and melted snow a year. December is the wettest month and July the driest. Rain or snow falls on about 64 days a year. Snow covers the ground about 62 days of the year.
About 166 frost-free days a year
In half of years the last 32° night comes by May 2 and the first one by October 14. That leaves about 166 frost-free days for gardens, shorter than 64% of U.S. towns.
Heating and cooling a home in Shoshone
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Shoshone, 89% of that work is heating and 11% 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 Shoshone itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Richfield, ID (15 mi, snow) and Jerome, ID (15 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
