“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 Osolo
Osolo gets 39 inches of rain and melted snow a year. May is the wettest month and February the driest. Rain or snow falls on about 144 days a year. Snow covers the ground about 40 days of the year.
About 175 frost-free days a year
In half of years the last 32° night comes by April 26 and the first one by October 21. That leaves about 175 frost-free days for gardens, shorter than 54% of U.S. towns.
Heating and cooling a home in Osolo
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Osolo, 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.
Osolo and its neighbors
Osolo borders 6 towns with climate data. January nights across them vary by 0.4°. Mason has the coldest January nights (17°) and Washington the hottest July afternoons (84°). Osolo’s January low is 17° and its July high 83°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.

Temperatures and rainfall come from NOAA’s gridded climate normals for Osolo itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Elkhart Pub Wks & Ut, IN (4 mi, snow) and Goshen 3sw, IN (12 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.
