HALEIWA, Hawaii (AP) — Surf's up on Oahu's famed North Shore, where crowds have been flocking to watch the largest waves of the winter season.

A high surf warning is in effect Wednesday for north and west facing shores across Hawaii.

Waves along Oahu's North Shore were expected to reach 30 feet Wednesday. Forecasters say the surf will lower to 10 to 18 feet by the evening and 6 to 12 feet Thursday.

Officials warned beachgoers to stay out of the water, but KHON-TV reports a bodysurfer needed to be rescued at Waimea Bay Wednesday morning. He was not hurt.
