“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 Mount Hood
Mount Hood gets 33 inches of rain and melted snow a year. December is the wettest month and July the driest. Rain or snow falls on about 126 days a year. Snow covers the ground about 51 days of the year.
About 142 frost-free days a year
In half of years the last 32° night comes by May 13 and the first one by October 3. That leaves about 142 frost-free days for gardens, shorter than 88% of U.S. towns.
Heating and cooling a home in Mount Hood
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Mount Hood, 98% of that work is heating and 2% 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.
