About these readings

Recent totals combine NOAA MRMS radar analysis, where available, with Open-Meteo weather estimates. Readings cover completed analysis hours and can lag the current time. Small, localized storms may differ from a backyard gauge.

Rainfall in Chicago, Illinois 60601

These readings estimate rain near this ZIP’s reference point, not an average across the entire ZIP. Use device location or search above for a more specific area. Nearby streets can receive different amounts during localized storms.

Today starts at midnight in the America/Chicago time zone. The 24-hour and 7-day totals are rolling windows through the displayed analysis time. Historical dates use local calendar days; the YTD graph compares the same completed dates with the 1991–2020 ERA5 average.

Local rainfall context for Chicago, Illinois 60601

Chicago rainfall is spread across the year, with warm-season thunderstorms, spring and autumn fronts, and large low-pressure systems all contributing. Storms near Lake Michigan can change quickly, and a narrow thunderstorm band may produce a much higher total on one side of the city than another.

Use the 24-hour and seven-day values together to separate a brief downpour from a wetter pattern. During cold weather, radar precipitation can include the liquid-water equivalent of snow, sleet, or mixed precipitation, so the number should not be read as measured rain alone. Official Chicago-area warnings and winter-weather information come from the National Weather Service.
