High Surf Advisory is in effect for the north-east facing shores of the Big Island until 6 p.m. Friday. Surf along east facing shores could reach heights of 6 to 9 feet. Expect strong breaking waves, shore break and dangerous currents that make getting into the water hazardous and swimming difficult.

A Small Craft Advisory is posted for all Big Island waters until 6 a.m. Saturday. Winds of 20 to 25 knots are expected and rough seas from 8 to 15 feet. Inexperienced mariners should avoid navigating in these conditions. The advisory for windward Big Island waters is set to expire on Friday at 6 p.m.

Hilo side: Surf is expected overhead to possibly double overhead at the best breaks.

Kona side: Spots that catch some of the wrap could see a slight bump in wave heights from ankle to possibly waist high. Breaks not exposed to the swell will be flat today.

South: Southeast shores open to the trade swell could see waves shoulder high or more, though sloppy and choppy conditions are expected. Minimal surf out of the southern hemisphere.

Screen Shot 2014-11-27 at 9.31.36 PMTrade winds are generating swell for windward spots on the Big Island. Conditions will be choppy and sloppy.

A mix of north-northwest and north-northeast swells today. A new north-northwest is expected to fill in today bringing overhead to possibly double overhead waves at the best exposures on the sets.

Another swell out of the northeast is expected to bring another round of overhead waves over the weekend. New northwest swell could start building over the weekend on top of our old swell. Wave heights expected in the overhead range.

If models are right, a series of swells will affect our northerly exposures the first week of December.

Super small trace amounts of swell expected out of the SPAC. Some small SW to S swells could fill in Friday/Saturday of next week if storms in the SPAC behave as forecasted.

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.
