Rain and snow in Ayers
Ayers gets 40 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 94 days a year.
About 181 frost-free days a year
In half of years the last 32° night comes by April 19 and the first one by October 19. That leaves about 181 frost-free days for gardens, longer than 54% of U.S. towns.
Heating and cooling a home in Ayers
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Ayers, 86% of that work is heating and 14% 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.
