Rain and snow in Summit
Summit gets 45 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 136 days a year. Snow covers the ground about 26 days of the year.
About 177 frost-free days a year
In half of years the last 32° night comes by April 27 and the first one by October 22. That leaves about 177 frost-free days for gardens, shorter than 51% of U.S. towns.
Heating and cooling a home in Summit
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Summit, 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.
