Recorded events in DuPage County by decade and hazard group. HailTornadoFloodWindWildfireLightningOther NCEI recorded only tornadoes, hail and thunderstorm wind before 1996.

Trend: 722 events in the 20 years to 2025 against 164 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
