Rain and snow in Westerville

About 142 frost-free days a year

Heating and cooling a home in Westerville
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Westerville, 91% of that work is heating and 9% 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Westerville itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Arcadia 1.7 W, NE (12 mi, snow) and Broken Bow 2 W, NE (15 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.
