Portland, Maine – Before you launch the boat or jump off the dock, check the forecast — because lightning can strike long before the rain starts.
More than 60% of lightning fatalities happen during outdoor recreation, often during everyday activities like fishing, boating and swimming. In Maine, the risk increases through late spring and peaks in summer, when fast-moving afternoon thunderstorms become more common.
Here’s what catches people off guard: lightning can travel miles away from a storm. It doesn’t need dark skies overhead. A bolt can strike open water even when the heaviest rain is still in the distance.
Lakes such as Sebago Lake, Moosehead Lake and Rangeley Lake — along with popular coastal boating areas — draw thousands of visitors once temperatures warm. Open water offers no shelter. Fishing rods, boat rails and masts can increase exposure, and a strike can disable electronics or cause serious injury.
The rule safety officials repeat is simple: if you hear thunder, you are close enough to be struck. Leave the water immediately and seek shelter inside a fully enclosed building or hard-topped vehicle. Docks, picnic shelters and trees do not provide 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 outing from turning dangerous.
