HONOLULU (HawaiiNewsNow) - A long-period northwest swell is expected to bring another round of huge and dangerous surf to the north and west-facing shores of most of the smaller islands this weekend.
The National Weather Service in Honolulu has issued a high surf warning for the north and west shores of Kauai, Niihau, Oahu and Molokai and the north-facing shores of Maui until 6 a.m. Monday.
Waves long the north and west shores of Kauai and Niihau and the north shores of Oahu, Molokai and Maui are forecast to build to 20 to 30 feet Sunday.
Surf along west shores is expected to rise to 15 to 22 feet lSunday.
Waves are expected to decline slowly Sunday night.
A high surf advisory is also in effect for the north-facing shores of the Big Island. Waves are expected to rise to 12-18 feet along exposed north-facing shorelines.
For beachgoers, the large waves will bring a dangerous shorebreak and dangerous currents, and entering the water could face significant injury or death. The waves may also sweep across large portions of beaches, which could sweep people out into the water. The waves may also impact north and west-facing harbor entrances., making it dangerous to navigate harbor channels.
This latest swell has big-wave surfers on standby for surfing competitions in the event the green light is given.
On Saturday, the Billabong Pipe Masters was called off due to insufficient wave heights, but organizers were closely monitoring the incoming swell.
“Monday also looks promising for excellent conditions and high-energy action as the World Title and Vans Triple Crown of Surfing titles move closer to concluding on a highly-anticipated Finals day,” Lauren Rolland of WSL said.
