Swell Summary
The High Surf Advisory (HSA) remains in effect for the east facing shorelines of Oahu, Molokai and Maui through this afternoon and for the east coast of Kauai through tonight. Higher east wind wave swell from the gale low will increase surf heights along many east facing coasts. Select north and south shores could experience east swell wrap that will produce slightly higher surf. East facing shore surf should quickly decline and fall below HSA thresholds Tuesday as this low moves west and away from the islands. A series of small, lower period south swells will maintain small surf along south facing shores throughout the week. No anticipated incoming north or west swell will keep surf nearly flat along most north and west exposures.
