About Lightning in Wisconsin

Located at approximately 43°N latitude, Wisconsin is bordered by Lake Michigan and Lake Superior, where Great Lakes effects can both suppress and enhance thunderstorm activity depending on wind direction and season. Thunderstorm frequency varies within state boundaries, so this page does not publish an unsupported statewide annual average or national rank.

In Wisconsin, frontal boundaries and warm moist air from the south converge across flat terrain. Peak thunderstorm activity occurs during June through August, when conditions align for the most frequent lightning strikes. With a population of 5.9 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Wisconsin.
