Big Island Surf Forecast

Hilo side: Wave heights are forecast to be double to triple overhead in some spots today at the best exposures along the northeast coast. North Kohala will see smaller yet still fun surf.

Kona side: Wave heights are expected to be knee/waist high today with a gentle decrease in heights through the day.

South: Wave heights are expected to be knee/waist high today with a gentle decrease in heights through the day.

Our current northwest pulse is expected to ease Tuesday. That same storm which generated the northwest pulse then re-intensifies to bring us a large north-northeast swell filling in Tuesday and peaking Wednesday before fading through the second half of the work week. Another small northwest is due in Thursday and Friday.

Nothing significant expected out of the South Pacific any time soon.

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.
