Swell Summary
A small pulse of medium period swell energy from the northwest should produce a slight bump in north facing surf heights tonight into Sunday morning. A small to moderate, medium period northwest swell will move into the region by Monday night and continue through Wednesday. A moderate, medium period northeast swell arrives Tuesday and peaks on Wednesday, bringing moderate surf to north-facing shores, before slowly declining through the end of the week.
A medium-period south swell will continue to fade tonight, allowing surf along south shores to return to background levels by Sunday. A series of overlapping small south swells will move into the region into next week. Surf heights along east-facing shores remain on the smaller side due to weaker trade winds until the arrival of the aforementioned northeast swell on Tuesday. Small background energy from the west will be possible, especially later in the week, from Severe Tropical Storm Sinlaku.
