“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 Rough and Ready
Rough and Ready gets 47 inches of rain and melted snow a year. December is the wettest month and July the driest. Rain or snow falls on about 74 days a year.
About 215 frost-free days a year
In half of years the last 32° night comes by April 10 and the first one by November 13. That leaves about 215 frost-free days for gardens, longer than 80% of U.S. towns.
Heating and cooling a home in Rough and Ready
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Rough and Ready, 84% of that work is heating and 16% 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 Rough and Ready itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Harry L Englebright Dam, CA (7 mi, snow) and Grass Valley #2, CA (4 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.
