The Purple Flag at the Beach: The Important Warning Most Beachgoers Ignore

does a purple flag stay up?
Until the marine pest hazard has passed. That could be hours, days, or even weeks (jellyfish blooms can last for weeks).

Does purple flag mean there are sharks?
In some regions, yes. Some beaches use purple to indicate shark sightings. But more commonly, purple indicates jellyfish, stingrays, and other marine pests. Ask a lifeguard for specifics.

I got stung and I’m allergic to shellfish. Should I be worried?
Jellyfish and shellfish allergies are different. A jellyfish sting won’t trigger a shellfish allergy. However, if you have a severe reaction (difficulty breathing, swelling of the throat, hives over a large area), seek emergency care immediately.

Can you get stung by a dead jellyfish?
Yes. The tentacles can still sting even after the jellyfish is dead and beached. Do not touch them.

What’s the best way to avoid sea lice?
Wear a rash guard. Shower immediately
