Swell Summary
The large north northwest swell (340 degrees) that brought warning level surf has been steadily easing based on latest near shore and offshore buoys. This swell will transition out of the north today and may receive a small reinforcement tonight that could keep surf elevated into tomorrow. A larger northwest (320 degrees) swell will build Thursday and continue through the weekend.
Surf along east facing shores will remain rough and choppy due to the combination of breezy trade winds and the north swell wrapping into exposed locations.
Overlapping, small, fading south swell and an incoming small, south- southwest swell will keep small surf along south facing shores for the next couple of days. The next small, long period south southwest swell is expected to fill in over the weekend.
