SSW Eases Late in The Day

Alerts

A High Surf Advisory has been posted for the south shore through 10:00 a.m. Thursday for surf heights of 5 to 8 foot faces. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.

A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as Big Island leeward and southeast waters through 6:00 p.m. Sunday. East winds up to 30 knots are forecasted along with rough seas of 9 to 15 feet. Inexperienced mariners should avoid navigating in these conditions.

Big Island Surf Forecast

Hilo side: Waist/head high surf is expected today. Messy conditions due to the winds.

Kona side: Wave heights of chest/head high are expected for southerly exposures. Best breaks could reach overhead occasionally on the sets.

South: Wave heights chest/head high today. Standout spots could get overhead waves on the sets.

Our current south-southwest is expected to ease late in the afternoon and throughout the night. Friday an incoming swell will overlap with the current one. That second pulse is expected to peak over the weekend and ease early next week.

A new northwest swell is expected to build Thursday, peaking late Friday up to waist high or so at the best spots.

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.
