Big Island Surf Forecast

Hilo: Wave heights are expected to be shoulder high to overhead.

Kona: Wave heights are expected to be around knee/thigh high and up to waist high today.

South: Wave heights are expected to be around knee/thigh high and up to waist high today.

Our new north-northwest swell is filling in and building through the work week. Advisory level surf is happening and may have to be expanded to include the west sides of some islands on Tuesday. This series of swells is forecast to trend down Thursday night and Friday.

A new north-northwest is expected to build Saturday.

The combo of north swell, north winds, high tides and beach erosion could lead to coastal flooding. Keep that in mind as you plan your day.

A northeast reinforcement is forecast to keep wave heights elevated through the first part of the work week.

A small south swell is forecast to fill in midweek.

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.
