Andres Generates Trade Swell

Alerts

The High Surf Advisory has been extended until Wednesday at 4:00 p.m. for surf from 5 to 8 feet along south facing shores. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.

A Small Craft Advisory has been posted for the Alenuihaha channel and waters to the south and west of the Big Island through 6:00 a.m. Wednesday. East winds up to 25 knots and rough seas of 6 to 10 feet are expected.

Big Island Surf Forecast

Hilo side: Waist/shoulder high waves expected today for trade swell magnets.

Kona side: Wave heights of head high to a few feet overhead are expected for southerly exposures.

South: Wave heights head high to a few feet overhead are expected today.

Our current south-southwest gradually fades over the rest of the week.

A slightly smaller south-southwest swell is expected from Wednesday into Saturday, peaking Thursday/Friday with likely surf near advisory levels.

Small and relatively short-period northwest swells are forecasted to continue throughout the week, with a slightly larger northwest expected next weekend.

Hurricane Andres in the far East Pacific has generated a long period east swell that is forecasted to persist into next weekend. Initial swells are expected to be small, but the swell is forecast to grow to the point that an advisory may be needed for east facing shores before next weekend.

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.
