“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 Whitewater
Whitewater gets 42 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 116 days a year. Snow covers the ground about 15 days of the year.
About 180 frost-free days a year
In half of years the last 32° night comes by April 24 and the first one by October 20. That leaves about 180 frost-free days for gardens, longer than 53% of U.S. towns.
Heating and cooling a home in Whitewater
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Whitewater, 85% of that work is heating and 15% 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.
How Whitewater 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 Whitewater averaged 1.2° warmer than the 1900s. The biggest change is in December (+2.2°). The shift is larger than in 51% of U.S. towns.

How much a month can swing

Temperatures and rainfall come from NOAA’s gridded climate normals for Whitewater itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at West Manchester 3 Wsw, OH (11 mi, snow) and Richmond Wtr Wks, IN (7 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.
