Swell Summary
The current long-period sout-southwest swell should hold through Friday at near average levels, and then gradually decline this weekend into early next week. Through much of next week, expect a mix of long- period background south- southwest and shorter- period southeast swell. Overlapping north-northwest swells will maintain surf along north and west facing shores at average levels into Friday. A second swell will drive heights above average on Saturday. Surf will gradually lower to seasonal levels Sunday through early next week. Surf along east-facing shores will gradually build over the weekend and into early next week as trade winds return.
