“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 Good Hope
Good Hope gets 39 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 109 days a year. Snow covers the ground about 13 days of the year.
About 185 frost-free days a year
In half of years the last 32° night comes by April 17 and the first one by October 22. That leaves about 185 frost-free days for gardens, longer than 58% of U.S. towns.
Heating and cooling a home in Good Hope
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Good Hope, 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Good Hope itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Macomb, IL (5 mi, snow) and Prairie City 2s, IL (11 mi, frost, heat and degree days).
