“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 Table Rock
Table Rock gets 8 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 61 days a year. Snow covers the ground about 74 days of the year.
About 106 frost-free days a year
In half of years the last 32° night comes by June 1 and the first one by September 16. That leaves about 106 frost-free days for gardens, shorter than 99% of U.S. towns.
Heating and cooling a home in Table Rock
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Table Rock, 97% of that work is heating and 3% 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 Table Rock itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Wamsutter, WY (22 mi, snow) and Bitter Creek 4 Ne, WY (6 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
