“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Coal
Coal gets 46 inches of rain and melted snow a year. September is the wettest month and February the driest. Rain or snow falls on about 134 days a year. Snow covers the ground about 40 days of the year.
About 172 frost-free days a year
In half of years the last 32° night comes by April 27 and the first one by October 20. That leaves about 172 frost-free days for gardens, shorter than 58% of U.S. towns.
Heating and cooling a home in Coal
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Coal, 90% of that work is heating and 10% 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.
Coal and its neighbors
Coal borders 7 towns with climate data. January nights across them vary by 1.8°. Mount Carmel has the coldest January nights (18°) and Ralpho the hottest July afternoons (83°). Coal’s January low is 19° and its July high 82°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
