“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 44 inches of rain and melted snow a year. July is the wettest month and November the driest. Rain or snow falls on about 141 days a year. Snow covers the ground about 24 days of the year.
About 181 frost-free days a year
In half of years the last 32° night comes by April 22 and the first one by October 21. That leaves about 181 frost-free days for gardens, longer than 54% 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, 89% of that work is heating and 11% 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 6 towns with climate data. January nights across them vary by 0.2°. Washington has the coldest January nights (23°) and Lick the hottest July afternoons (85°). Coal’s January low is 23° and its July high 85°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Coal compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Coal averaged 1.1° warmer than the 1900s. The biggest change is in December (+2.8°). The shift is smaller than in 57% of U.S. towns.

Temperatures and rainfall come from NOAA’s gridded climate normals for Coal itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Mc Arthur, OH (12 mi, snow) and Jackson 3 Nw, OH (6 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
