Naperville hail storm history
DuPage County·NOAA NCEI Storm Events Database·~75-day publication lag
Naperville, located in DuPage County, sits in the Chicago metropolitan area where hail risk is shaped by the region's continental climate and Lake Michigan's moderating influence. The western and southern suburbs of the Chicago metro, including Naperville, experience hail more frequently than areas closer to the lakeshore, as lake-breeze boundaries can locally intensify storm development during the peak season.
Check if your roof was damaged by recent hail
Hail in Naperville occurs most frequently during April, May, and June, when atmospheric conditions favor the development of severe thunderstorms across DuPage County. March and July represent secondary risk months in the region. During these periods, the combination of warm surface air and upper-level wind shear creates environments where hail-producing storms develop, with the largest stones typically occurring in spring and early summer convection.
