Rain and snow in Chilo
Chilo gets 46 inches of rain and melted snow a year. May is the wettest month and November the driest. Rain or snow falls on about 131 days a year.
About 196 frost-free days a year

Heating and cooling a home in Chilo
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Chilo, 81% of that work is heating and 19% 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.
