The monthly box jellyfish influx came a day late and hit an unusual spot.

Honolulu's Ocean Safety officials found more than 1,000 box jellyfish yesterday at Waikiki and Ala Moana Beach Park.

The influx came 11 days after the last full moon instead of the typical 10, said Emergency Services spokesman Bryan Cheplic. Also, of the 1,000 found, 400 were at Ala Moana.

"That's unusual," Cheplic said. "With the reef outside of Ala Moana, it typically doesn't get many, if any, jellyfish during the influx. Last month when 2,000 were found in Waikiki, zero were found at Ala Moana.

"I couldn't tell you why that happens. It's just Mother Nature being highly unpredictable again."

Monday was supposed to be the peak day for the influx, but none were reported on any O'ahu beaches. Cheplic said he isn't sure what to expect today, but lifeguards and ocean safety officials will again comb the beaches and monitor the waters.

If box jellyfish are discovered, warning signs are posted as warranted.

Seventy people were treated yesterday for stings in Waikiki today and 12 more were treated at Ala Moana Beach Park.

Cheplic said 165 box jellyfish were also found at Poka'i Bay, but no stings were reported.

People stung by box jellyfish are advised to flush the sting area with plenty of white vinegar.

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