Rain and snow in Adrian
Adrian gets 9 inches of rain and melted snow a year. May is the wettest month and August the driest. Rain or snow falls on about 78 days a year.
About 165 frost-free days a year

Heating and cooling a home in Adrian
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Adrian, 88% of that work is heating and 12% 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 Adrian itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Parma Exp Stn, ID (8 mi) away. Normals are 30-year averages, not a forecast.
