Swell Summary
A small, long-period WNW swell holds steady tonight along north and west shores before fading Friday and dropping north shores to flat/tiny by the weekend.
Meanwhile, south-facing shores remain slightly below average as old SW and WNW swells fade, but a fresh SSW swell arriving late Friday will briefly boost surf back to near average. A larger, moderate south swell is expected to build Sunday through early next week, bringing potentially above-average (though sub-advisory) waves to south shores.
On east-facing shores, strengthening trade winds will make surf slightly bigger and choppy this weekend, with a potential small-to- moderate swell arriving early-to-mid next week from Tropical Storm Elida.
