Many Delaware beachgoers feel the sting of a blooming jellyfish population
August 6, 2025
More beachgoers have been getting an unexpected shock this summer as jellyfish numbers bloom along the Delaware coast. Many beach patrol captains say they’re seeing the most jellyfish activity and stings in recent memory. Dramatic increases were reported at Delaware’s two most popular beaches in July. Lewes Beach is one of them. It had over four times as many stings in July compared to the same month last year. Lion’s manes, sea nettles and moon jellyfish are some varieties that frequent Delaware’s summertime waters, but the sudden boom has shocked beachgoers. A beach patrol captain says he has never seen this many jellyfish or reports of stings.
