Tornado Activity Increasing in Wisconsin Amid Changing Weather Patterns
US · Published Aug 10, 2026
Tornado activity in Wisconsin has been on the rise, with the state experiencing some of its busiest tornado years in the last two decades.
In 2026 alone, Wisconsin has already surpassed its annual average of 23 tornadoes, with 39 confirmed as of mid-July.

Impact & Risks

The increasing frequency of tornadoes in Wisconsin poses significant risks, particularly in southern counties where most tornadoes occur during the late afternoon. Tornadoes during the evening rush can disrupt traffic, delay emergency responses, and cause widespread damage to infrastructure. The state has also seen an uptick in out-of-season tornadoes, such as those in February 2024 and December 2021. With 2026 already recording four EF3-strength tornadoes, the highest since 1984, the potential for severe damage remains high.
