About Lightning in Iowa

Located at approximately 42°N latitude, Iowa is fertile agricultural land in the upper Midwest, where nocturnal mesoscale convective systems and daytime heating drive frequent summer thunderstorms across the corn belt. Thunderstorm frequency varies within state boundaries, so this page does not publish an unsupported statewide annual average or national rank.

In Iowa, frontal boundaries and warm moist air from the south converge across flat terrain. Peak thunderstorm activity occurs during May through August, when conditions align for the most frequent lightning strikes. With a population of 3.2 million residents, storm awareness and lightning safety are important considerations for anyone living in or visiting Iowa.
