Lansing, Mich. – Before you launch the boat or settle in along the shoreline, check the forecast — because lightning can strike long before the rain reaches you.
More than 60% of lightning fatalities happen during outdoor recreation, often during everyday activities like boating, fishing and swimming. In Michigan, the risk increases in late spring and peaks during the summer months when fast-developing afternoon thunderstorms become more common.
Here’s what surprises many people: lightning can strike miles away from a storm. It doesn’t have to be raining overhead. If you can hear thunder, you are already within striking distance.
Open water increases exposure. Popular destinations along Lake Michigan, Lake Huron, Lake Superior and Lake Erie — along with inland lakes across the state — draw heavy seasonal crowds. Boat masts, fishing rods, docks and exposed shoreline areas offer little protection, and a direct strike can cause serious injury or disable onboard electronics.
Safety officials emphasize a simple rule: at the first sound of thunder, leave the water immediately and seek shelter inside a fully enclosed building or hard-topped vehicle. Beach shelters, pavilions and trees do not provide safe protection.
For students, seasonal workers and summer visitors, peak recreation season also brings peak lightning danger.
Checking the forecast before heading out — and being willing to delay plans — can prevent a routine summer outing from turning into an emergency.
