Advisory Level Surf Expected Today
A High Surf Advisory has been issued by the National Weather Service for our north shores until Midnight due to a north-northwest swell that built in overnight.
Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.
A Small Craft Advisory is posted until Midnight for Big Island windward waters due to expected rough seas up to 12 feet. The Alenuihaha Channel can also expect east winds up to 25 knots while Big Island leeward waters may experience rough seas to 11 feet and southeast winds up to 25 knots.
A Small Craft Advisory is also posted for southeastern waters until 6 p.m. Wednesday.
Inexperienced mariners should avoid navigating in these conditions.

Hilo side: Surf is expected shoulder high early in the day but expected to build to double overhead by the end of the day at the best breaks on the sets.
Kona side: Breaks not exposed to the swells will be flat today. Spots that catch some of the new north-northwest wrap could see waves up to waist high by sunset.
South: Waves expected waist high or less. Southeast shores open to the trade swell could see waves up to shoulder high though sloppy and choppy conditions are expected.
Our current north-northwest swell (325-350°) continues to fade through the day while a new, larger north northwest swell (330-350°) is expected to fill in through the day today, peak in the afternoon at advisory level heights, then gradually lower Tuesday and Wednesday. We expect to see another round of overhead to double overhead surf for the best breaks along the Hamakua coast.
Another, but slightly smaller northwest swell is expected to slowly build Wednesday afternoon and peak through the day on Thursday before gradually fading on Friday.
Super small trace amounts of swell expected out of the SPAC. There isn’t much on the horizon out of the South Pacific. Possibly a small bump building on Tuesday but not expected to be over waist high at the best breaks.
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.
