A High Surf Advisory is in effect for north exposures of the Big Island. The advisory is posted through Saturday at 6 a.m. Surf heights from 10 to 15 feet are expected. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.
A Small Craft Advisory is posted for all island waters through 6 a.m. Saturday. Northeast winds up to 30 knots are expected along with rough seas of 10 to 16 feet. Inexperienced mariners should avoid navigating in these conditions.

South: Wave heights of waist to belly high are expected. Standout spots could get up to chest high on the sets.
Our current north-northwest swell is expected to slowly fade through the weekend. Most of the size will show for the northeast or Hilo coastline while the Kona side will be heavily shadowed from this swell.
A northwest pulse is expected late this weekend. A recent storm near Japan is also expected to bring us a west-northwest swell early next week. Will keep an eye on these.
Our current Tasman swell is expected to continue to build and peak Saturday before slowly fading through Sunday.

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.
