“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 Galena
Galena gets 50 inches of rain and melted snow a year. May is the wettest month and February the driest. Rain or snow falls on about 124 days a year.
About 225 frost-free days a year
In half of years the last 32° night comes by March 31 and the first one by November 9. That leaves about 225 frost-free days for gardens, longer than 84% of U.S. towns.
Heating and cooling a home in Galena
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Galena, 72% of that work is heating and 28% 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Galena itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Louisville Mcalpine, KY (10 mi) away. Normals are 30-year averages, not a forecast.
