Big Island Surf Forecast

Hilo side: Wave heights are expected head high today with the best breaks getting up to a few feet overhead from time to time on the sets.

Kona side: Wave heights knee/waist high are expected today – just small leftovers.

South: Breaks open to the south-southwest swell could get up to knee/waist high – just small leftovers. Breaks open to the trade swell could get up to head high or even overhead.

An advisory level east-northeast trade swell will continue to affect windward coasts through the weekend.

Our current south-southwest continues to trend down today.

A new northwest swell is expected to overlap and shows for the weekend. A slightly larger northwest swell is expected to build midweek but be rather short-lived.

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.
