Rain and snow in Vermont
Vermont gets 38 inches of rain and melted snow a year. June is the wettest month and January the driest. Rain or snow falls on about 85 days a year. Snow covers the ground about 61 days of the year.
About 148 frost-free days a year
In half of years the last 32° night comes by May 7 and the first one by October 1. That leaves about 148 frost-free days for gardens, shorter than 82% of U.S. towns.
Heating and cooling a home in Vermont
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Vermont, 93% of that work is heating and 7% 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.
