Big surf brought a lot of visitors and residents to Oahu's North Shore on Christmas Day.
The surf was 12-to-18-feet-tall, according to city's Emergency Services Department.
Lifeguards were extremely busy with more than 1,300 preventative actions and 18 rescues, as of 4:15 p.m. Tuesday.
Three of the rescues required paramedics. A 27-year-old woman surfing at Waimea Bay injured he leg at around 2:45 p.m. She was rescued by lifeguards on their rescue craft and transported to the hospital in serious condition.
The most preventative actions were seen at Laniakea Beach, with about 350 preventative actions, and at Waimea Bay, with about 250 preventative actions.
Ocean Safety officials are asking the public to continue to check with lifeguards for the best information on the surf conditions.
