An incredible number of beach goers were stung by box jellyfish on Thursday. They were spotted at Ala Moana Regional park, Makaha, and Waikiki.
The jellyfish were out in full force, stinging 145 people. In Waikiki alone, 118 were spotted. The beach there was full of warning signs letting people know that jellyfish were reported on the beach and in the water near the shore.
Surf board rental companies said jellyfish warnings hurt their business every month.
"We are like 70 percent surfing lessons down. Like a lot of surf instructors and captains they lean back because they know it's no use getting people in the water because they don't want to see anyone in pain," said Mahesh Pandey with Star Beachboys.
On average, jellyfish are by the shore mostly on the ninth day after a full moon. Thursday was the tenth day after the full moon.
The number of jellyfish should drop by Saturday.
