“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 Keno
Keno gets 19 inches of rain and melted snow a year. December is the wettest month and July the driest. Rain or snow falls on about 93 days a year. Snow covers the ground about 40 days of the year.
About 107 frost-free days a year
In half of years the last 32° night comes by June 5 and the first one by September 20. That leaves about 107 frost-free days for gardens, shorter than 99% of U.S. towns.
Heating and cooling a home in Keno
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Keno, 96% of that work is heating and 4% 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.
