Swell Summary
An above average south swell has begun a slow decline, which will continue over the next few days. No other significant south swells are expected through early next week, although small, moderate period swells will prevent surf from going flat.
A small northwest pulse will continue to trend down through this morning, with no significant northerly swells expected through the forecast period. The easterly swell from Hurricane Linda is beginning to arrive and will spread west through Thursday and maintain moderate surf along east facing shores through the weekend. Wind waves will be small though, given the anticipated lighter winds.
