“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 Trail
Trail gets 33 inches of rain and melted snow a year. December is the wettest month and August the driest. Rain or snow falls on about 127 days a year.
About 171 frost-free days a year

Heating and cooling a home in Trail
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Trail, 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 Trail itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Lost Creek Dam, OR (7 mi) away. Normals are 30-year averages, not a forecast.
