“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 Pilot
Pilot gets 40 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 134 days a year. Snow covers the ground about 31 days of the year.
About 182 frost-free days a year
In half of years the last 32° night comes by April 20 and the first one by October 21. That leaves about 182 frost-free days for gardens, longer than 55% of U.S. towns.
Heating and cooling a home in Pilot
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Pilot, 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.
Pilot and its neighbors
Pilot borders 5 towns with climate data. January nights across them vary by 0.7°. Middlefork has the coldest January nights (17°) and Ogden the hottest July afternoons (85°). Pilot’s January low is 18° and its July high 85°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.

Snow, frost dates and day counts come from NOAA’s weather station at Ogden, IL (9 mi) away. Normals are 30-year averages, not a forecast.
