Current Swell Fades, Advisory Level Swell For Weekend
A Small Craft Advisory is posted for all Big Island waters from 6:00 p.m. Friday through 6:00 a.m. Saturday for northeast winds up to 20 knots with higher gusts. Rough seas of 5 to 10 feet are also forecasted. Inexperienced mariners should avoid navigating in these conditions.

Hilo side: Surf heights are expected head high to overhead at the best breaks open to the swell.
Kona side: Surf heights are forecasted from knee to about waist high. Possibly shoulder high at the best exposures.
South: Southerly spots are below waist high today. Exposures open to the east-southeast are forecasted to get shoulder to head high surf.
Our current north-northwest (330-360) swell is expected to continue to fade. The Kona side is shadowed from this swell, just small leftovers expected.
Another west-northwest is expected over the weekend, building on Saturday. This swell will likely produce advisory level surf along north and west facing shores as early as Friday evening. The swell will gradually subside through the weekend.
Pending development of storms, another shot of energy is expected early next week as well, with surf likely well above the advisory level along north and west facing shores. That swell will slowly subside through midweek. A northwest swell arriving next midweek may be larger still when it peaks next Thursday.
Nothing of note out of the SPAC to get excited about.
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.
