Tornado Season Begins in Chicago: What to Expect and How to Stay Safe
US · Published May 13, 2026
Tornado season has officially started in Chicago, running from April 1 through June 30, according to the National Weather Service (NWS).
This period typically sees around 80% of tornado occurrences, primarily in the afternoons and evenings.
Recent years have been record-breaking for tornado activity in northeast Illinois and northwest Indiana, with 2024 holding the record for the most tornadoes in the region.

Why It's Important?

Tornadoes pose significant risks to life and property, especially during peak season. In recent years, Cook County has experienced multiple tornadoes, including EF2 storms with wind speeds between 111 and 135 mph. While the majority of tornadoes are weaker EF0 storms, even these can cause localized damage. The unpredictability of tornadoes makes it crucial for residents to have access to emergency alerts and a plan for seeking shelter. The National Weather Service emphasizes the importance of staying vigilant, particularly during afternoons and evenings when tornado activity is most likely.
