Rain and snow in Fall Lake
Fall Lake gets 28 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 125 days a year.
About 127 frost-free days a year
In half of years the last 32° night comes by May 21 and the first one by September 25. That leaves about 127 frost-free days for gardens, shorter than 96% of U.S. towns.
Heating and cooling a home in Fall Lake
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Fall Lake, 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.
