Swell Summary
A few overlapping northwest swells are scheduled to arrive this week. The latest moderate size, long period northwest (310-320 degree) swell peaked surf to near or slightly under High Surf Advisory (HSA) thresholds along most north and west-facing Kauai-to-Maui shores last night into early morning. This swell will decline through the afternoon and into Tuesday to then be followed by a slightly larger northwest (310-330 degree) swell building in Tuesday night. As a result, the arrival of this high end moderate size, long period swell will likely produce mid week advisory level north and west- facing shore surf. North and west shore surf will fall below HSA heights Thursday. A moderate size northwest (310 degree) swell is due next weekend. A weak pulse of early season, south southwest (200 degree) swell has been passing through the past day or so. Expect this inconsistent swell to peak south-facing shore surf at slightly above March averages today, then gradually decline through Wednesday. East shore surf will remain small through the middle of the week. There will be a slight pick up in chop later this week in response to strengthened trades.
