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 well below waist high for most spots today – just small leftovers.
South: Most breaks are well below waist high – just small leftovers. Breaks open to the trade swell could still get up to head high or even overhead.
Our current south-southwest continues to trend down today.
Our current north-northwest swell is fading today. A much larger northwest swell is expected to build midweek with some spots possibly reaching triple overhead by Wednesday night.
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.
