Swell Summary
Choppy surf along east facing shores will hold through the first half of next week due to persistent trades locally and upstream. A small, long-period south-southwest swell will peak today, generating small surf through Sunday before declining Monday. Background southeast and south swells will then keep tiny surf along south facing shores through much of next week. Surf along north facing shores will remain nearly flat through much of next week. Models show a gale low developing and tracking along the Aleutian Islands early next week that may send a small northwest swell into the local waters toward the end of next week.
