Swell Summary
The High Surf Advisory remains in effect for S and W shores as long period S swell peaks today and remains elevated through tonight. Surf associated with this swell then begins to diminish as the period shortens. Another long period S swell arrives late Sunday into Monday bringing another boost to surf.
For E shores, surf initially trends slowly upward in association with gradually strengthening trades. Additional swells generated by TC Lala will arrive on Friday followed by the main energy arriving with the system itself this weekend. Surf along E facing shores is expected to exceed the High Surf Warning threshold during this time. Based on the latest forecast track and intensity from the National Hurricane Center, dangerous surf will develop around Maui and the Big Island on Saturday and around Oahu and Kauai Saturday night into Sunday.
