South facing Hawaii beaches are most impacted by jellyfish eight days after a full moon. These include Waikiki, Ala Moana Beach Park, Haunama Bay and the Waianae Coast on Oahu. Kauai can have warning signs posted at Poipu Beach. Maui beaches and Big Island beaches are also affected but typically have fewer problems.
Here in Hawaii, jellyfish types include the box, moon and lagoon varieties.
Awareness. Check with a lifeguard for sure and look for jellyfish washed up on the sand as an indication of a problem.
Timing. You’ll usually find jellyfish on impacted beaches eight days following a full moon. The problem can persist for three days. If you’re here during a jellyfish invasion, talk to the lifeguard for advice. Also check the beach to see if any jellyfish have washed ashore.

Searching online will yield a wide range of suggestions for what to do in the event of a jellyfish sting. Some of the best suggestions we’ve seen include the following:
- Seek medical attention as soon as possible if in shock or if you have any complications.
- Rinse the site with vinegar to deactivate the toxins and help remove the remaining tentacles and nematocysts. Others say to wash the area with seawater to deactivate stinging cells. Or you can remove tentacles by scraping with a credit card or other plastic object.
- Use hot water or ice packs to reduce the pain duration and intensity. Others suggest after removing the tentacles, immerse the affected arm or leg in hot water of 104 to 113°F for at least twenty minutes. If other body parts are impacted, a hot shower can be used instead.
