Swell Summary
The current moderate period south-southwest swell will continue to decline through tonight. Expect mainly background energy along south-facing shores on Thursday. A tiny long-period south- southwest swell is possible this weekend. Otherwise, expect mainly background energy through the middle of next week.
Surf along east-facing shores will remain rough and choppy the next several days due to the fresh to locally strong trades. Surf along north-facing shores will remain small with some background northwest energy moving through throughout the week and into the weekend.
