North: Wave heights are expected waist/head high today for spots catching the tropical swell. Shadowed spots will be smaller with most size showing for Hana. Swell builds through the day.
West: Wave heights knee/thigh high are expected today as our SSW fades. Spots shadowed by other islands will be smaller.
South: The south-southwest is expected to bring knee/thigh high waves today. Spots open to the tropical swell could get up to waist/chest high and building as the day goes on.
Trade winds will continue to generate short-period choppy surf at moderate levels along east facing shores through the weekend. Niala will direct short-period swell primarily toward east-facing shores of the Big Island. Surf and storm surge are expected to build up to 8 to 12 feet along southeast facing shores. Overnight and afternoon high tides of about 2 feet will bring wave run up slightly higher during those times. Wind, surf, and seas are expected to decline gradually early next week as Niala weakens and moves away from the state.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
