A High Surf Advisory is in effect through 6:00 p.m. Tuesday. Along east facing shores we expect surf to build Monday into Tuesday. Surf heights of 8 to 12 foot faces are expected Monday and 10 to 14 feet through Tuesday. This advisory may need to be upgraded to a warning depending on conditions. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.

A Small Craft Advisory is in effect for all the Alenuihaha channel and waters to the south and west of the Big Island through 6:00 a.m. Monday. East winds up to 25 knots and rough seas to 11 feet are expected. Inexperienced mariners should avoid navigating in these conditions.

Screen Shot 2015-08-02 at 6.08.53 PMGuillermo is expected to bring large waves to eastern exposures starting today and into Tuesday. The Hilo side will see the most energy. Will keep an eye on this situation as Guillermo continues to approach and let you know if the system warrants an upgrading of the High Surf Advisory to a High Surf Warning.

Small to modest ENE tradeswell will also blend in. Nothing out of the NPAC is expected.

Super small southern hemi mix is expected through Tuesday. A better swell is expected for the second half of the work week.

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.
