Sign at Hanauma Bay on Oahu

City officials this morning will reassess whether to reopen Hanauma Bay after it was closed yesterday because of the monthly box jellyfish invasion.

Lifeguards spotted more than 20 box jellyfish in less than an hour yesterday morning and countless more floating just offshore.

More than 650 box jellyfish were also found on Waikiki Beach, but no stings were reported.

Lifeguards advise people stung by box jellyfish to flush the sting area with plenty of white vinegar.

Anyone experiencing breathing difficulty, muscle cramps, spasms or persistent pain is advised to seek immediate medical attention.

On Kaua’i, Ocean Safety Bureau officials yesterday closed Salt Pond Beach Park in Hanapepe after more than 400 box jellyfish were spotted.

Guarded beaches remained open at Anahola, Hanalei, Kealia, Kekaha, Lydgate and Po’ipu.

For public information regarding ocean conditions, advisories and warnings on O’ahu, the Ocean Safety and Lifeguard Services Division provides a report at 922-3888, ext. 51, or at www.hawaiibeachsafety.org or www.808jellyfish.com.
