“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 Reo
Reo gets 49 inches of rain and melted snow a year. April is the wettest month and August the driest. Rain or snow falls on about 104 days a year.
About 196 frost-free days a year
In half of years the last 32° night comes by April 12 and the first one by October 25. That leaves about 196 frost-free days for gardens, longer than 70% of U.S. towns.
Heating and cooling a home in Reo
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Reo, 74% of that work is heating and 26% is cooling.
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 Reo 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 Reo averaged 0.8° warmer than the 1900s. The biggest change is in December (+1.8°). The shift is smaller than in 82% of U.S. towns.

How much a month can swing
A normal is an average, and real years wander around it. December swings the most: between 1991 and 2020 its average temperature ranged from 25° to 48°. October is the most reliable, staying within 9°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Reo itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Owensboro 3e, KY (9 mi, snow) and Boonville 1s, 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.
