Rain and snow in Aniwa
Aniwa gets 32 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 113 days a year. Snow covers the ground about 116 days of the year.
About 141 frost-free days a year

Heating and cooling a home in Aniwa
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Aniwa, 97% of that work is heating and 3% 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.
