Rain and snow in Summit Park
Summit Park gets 30 inches of rain and melted snow a year. January is the wettest month and July the driest. Rain or snow falls on about 96 days a year.
About 117 frost-free days a year
In half of years the last 32° night comes by May 29 and the first one by September 25. That leaves about 117 frost-free days for gardens, shorter than 98% of U.S. towns.
Heating and cooling a home in Summit Park
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Summit Park, 98% of that work is heating and 2% 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.
