Swell Summary
High Surf Advisory (HSA) remains in effect through Saturday for the current moderate-to-large medium period NNE (010-030) swell. Another pulse out of the NNE will arrive on Friday causing another boost in surf along east-facing and other exposed shorelines. The swell will then steadily decline through the weekend. Small, mixed medium to long period NE/E swells emanating from the Gulf of Alaska and Hurricane Kristy then arrive early next week maintaining elevated surf along east facing exposures and potentially borderline HSA conditions. Strengthening trades will also cause an increase in short period trade wind swell during this time. Surf along south facing shores will remain small as the tiny long-period swell from the south- southwest, will hold tonight before declining Thursday. A slightly larger south swell is possible this weekend.
