A high surf advisory has been issued for east-facing shores of Kauai, Oahu, Molokai, Maui and the Big Island, and south-facing shores of all Hawaiian isles, in effect through 6 p.m. today.

Weather officials said swell from tradewinds and Hurricane Sergio will produce elevated surf along east-facing shores. A swell from the southern hemisphere, meanwhile, will produce large surf along south facing shores.

Surf is expected to reach heights of 5 to 8 feet along east-facing shores, and 6 to 10 feet along the south-facing shores of all Hawaiian isles.

The east swell will gradually decline through today, according to officials, while the south swell is expected to peak today, then decrease tonight through Saturday.

Expect strong, breaking waves, shore break and strong currents, making swimming difficult and dangerous. The public is advised to exercise caution and heed all advice from Ocean Safety officials.
