About Lightning in Minnesota
Minnesota averages 36 thunderstorm days per year, placing it above the national average of 25 days. Located at approximately 45°N latitude, Minnesota is the Land of 10,000 Lakes in the upper Midwest, where clashing Arctic and Gulf air masses produce powerful summer thunderstorms, especially along the western prairies.
In Minnesota, 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 5.7 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Minnesota.
