NW Swell Brings Waves Well Overhead
A Small Craft Advisory is posted for all Big Island waters until 6 p.m. Wednesday. Winds around 25 knots are expected out of the northeast and rough seas of 7 to 15 feet. Inexperienced mariners should avoid navigating in these conditions.
**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: Surf is expected head high to well overhead at the best breaks due to a mix of tradeswell and northwest swell.
Kona side: Spots that catch some of the wrap could see a slight bump in wave heights, waist high or less. Breaks not exposed to the swells will be flat today.
South: Southeast shores open to the trade swell could see waves up to head high or more, though sloppy and choppy conditions are expected. Minimal surf out of the southern hemisphere.
Our current northwest swell (305-330°) is expected to keep wave heights in the head high to possibly well overhead range along the Hamakua coast. By midweek the swell is expected to begin fading. Kona side will be shadowed but still catch a fraction of the wrap.
Another swell out of the northeast is expected to bring another round of overhead waves late this week. There’s also the possibility of a new northwest swell for the weekend.
Super small trace amounts of swell expected out of the SPAC. A tiny southerly swell could bring wave heights up to thigh high tomorrow. There isn’t much on the horizon 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.
