Hanauma Bay has been closed for a second day after more than 40 box jellyfish were found in less than an hour today “with countless more spotted floating just offshore,” according to the city’s Emergency Services Department.

“A smaller number of box jellyfish” also were found on Waikiki Beach this morning, along with Portuguese man-of-wars.
“Due to the potential risk to public safety the city’s Parks and Recreation Department along with the Ocean Safety and Lifeguard Services Division made the decision to close the bay effective at 7 a.m.,” said Bryan Cheplic, spokesman for the Honolulu Emergency Services Department.
Today 56 box jellyfish and 10 Portuguese man-of-war were found along Waikiki Beach and one person was treated by lifeguards for a sting.
In less than an hour yesterday, more than 30 people were treated for stings at Hanauma Bay, prompting its closure at 9:30 a.m. More than 500 box jellyfish were also found on Waikiki Beach yesterday, with more than 50 people having to be treated for stings.
