Ocean Safety personnel kicked off what is traditionally one of their busiest long weekends of the year with a pair of morning rescues Friday in Makapuu.

About 11:15 a.m., Ocean Safety personnel responded to an emergency call at the Makapuu tide pools, where a 22-year-old woman was injured after being knocked over by a wave.

A rescue watercraft was used to retrieve the woman, who declined transport to a hospital.

About 11:50 a.m., lifeguards assisted a 51-year-old man who hit his head on the shoreline at Makapuu Beach. The man was transported in serious condition to a trauma center.

Ocean Safety and Emergency Medical Services are reminding people to know their capabilities and to not push their limits.
