Swell Summary
A moderate, long period south swell is expected to build in early Monday. This swell may peak just below High Surf Advisory (HSA) criteria late Monday and into Tuesday before declining Wednesday. Another swell is expected from a low formed south of New Zealand at the end of July, that measured seas of 35 to 40 feet aimed towards Hawaii. This swell is expected to build on Thursday and hold through the end of the week which could get near HSA criteria at its peak.
Short period trade wind swell will keep east facing shores elevated and choppy through Monday due to strong trade winds. By late Monday into Tuesday, a moderate, medium to long period east swell is expected to fill in from the energy from former Tropical Cyclone Gil.
A small, medium period northwest swell originating from Typhoon Krosa in the western Pacific will bring a small bump up in surf along north facing shores this evening and hold through Monday. Another bump is expected as a small, medium to long period northwest swell looks to fill in Thursday and Friday.
