Swell Summary
Relatively small, medium period east swell originating from former Tropical Cyclone Jova has been building into the local waters. This swell will hold above seasonal average east-facing shore surf through the day. This swell will begin its gradual decline early Wednesday. Eastern exposures will experience more typical small, short period trade wind swell that produce below seasonal surf through the remainder of the week. As this ongoing small 2 foot, medium 14 second south (180-190 degree) swell passes around the island chain, south-facing shore waist to near chest high surf will remain just below late summer normals through today. This swell will fade Wednesday, with another small bump in south shore surf due this weekend. Small surf along those west shores better exposed to south wrap. Flat conditions along north-facing shores with no significant northern swell anticipated the next several days.
