(BIVN) – The National Weather Service in Honolulu yesterday issued a High Surf Advisory, which is still in effect until 6 p.m. HST this evening.

Surf along north facing shores will be 15 to 20 feet this morning, forecasters say, lowering to 10 to 14 feet late this afternoon. Surf will be trending lower through today.

Beachgoers, swimmers, and surfers should heed all advice given by ocean safety officials and exercise caution, forecasters say. When in doubt, do not go out.

According to a special weather statement, surges are still possible with all north facing harbors.

“The current north swell is trending lower,” the National Weather Service stated, “but is still large enough to produce light to moderate surges in all north facing harbors especially this morning. Places such as Haleiwa boat
Harbor,Hilo and Kahului harbors are susceptible to this swell. This swell also has the potential of producing large breaking waves near channel and harbor entrances. Mariners using these harbors should exercise caution when entering or leaving port and when mooring or launching vessels.”
