Increased trade winds and north-northeast swell will continue to support the High Surf Advisory (HSA) for exposed, east-facing coastal surf until Sunday. The next noteworthy north-westerly swell should run around the islands on Wednesday and Thursday. This moderate altitude and lower period northwest swell can bring the surf along the north and west facing coastline to HSA levels on Wednesdays and Thursdays. Periodic small, long swellings from southwest to south emanating from storms south of New Zealand will add a slight boost to the south-facing surf in the middle of the week.
