2023 Hawaii Jellyfish Sting | Cause, Treatment, Warning Dates

Jellyfish Sting in Hawaii This Week? Why You’re Not Alone!

It’s jellyfish sting week in Hawaii. We’re waiting for the first news at places like Oahu’s Hanauma Bay, which is sometimes closed when an influx of people report being stung. Other Oahu beaches are also typically affected. This month’s influx will start after today and continue through Saturday.

We tend to stay out of the water when we see jellyfish on the sand at south-facing Hawaii beaches. These are just nothing to mess with.

Jellyfish Invasion As Groundbreaking Research Determines Cause.

Click the title link above for more information on the study. What they discovered at UH makes Hawaii Box Jellyfish unique among the 40 global species. It’s now known why they are found on Hawaii’s south shore beaches approximately ten days after each full moon. Their appearance correlates with the specific nights of the lunar month – referred to as Kaloa in the Hawaiian calendar, with a critical number of hours of darkness after sunset and before sunrise. This clockwork lunar spawning migration behavior is unique.

Beat of Hawaii suggestions.

  • Avoid south-facing beaches from 8 days after a full moon until 12 days after a full moon (with 10 days being the peak period). Waikiki Beach and Ala Moana Beach Park are both susceptible to jellyfish.
  • Wear protective clothing (rash guards) in the ocean. In Australia’s Queensland, people have taken to wearing full-on protective suits.
  • Consider a range of products to alleviate the sting. We’ve been using After Bite, although a range of new anti-sting products are now available and more are coming.

  1. My husband was stung about 6:30 am May 2022 off S. Kihei. The welts started over his left chest, underarm, down his left side to his lower left back. Fire Department instructed him to submerse in hot tub of water to start pulling the poison out of his system. Oral benedryl to help with swelling and pain. It was a couple hard days waiting for the pain to subside. Today, the welts are faintly seen.

  2. Rubbing Alcohol seems to be what the fire department used when a loved one was stung, nothing else released the pain.
