Swell Summary
The current long-period south-southwest swell will produce elevated surf along south facing shores today, before it slowly lowers on Friday. A reinforcing south swell arriving Saturday will maintain surf near the seasonal average along south facing shores this weekend. Surf will gradually lower along south facing shores early next week. Surf will remain below the seasonal average along north facing shores through early next week. The current small northwest swell will fade late Friday. A small, short-period north-northwest swell is possible this weekend, followed by another small northwest swell next Tuesday. The weak trade winds over and upstream of the islands will maintain small surf along east facing shores through early next week.
