Swell Summary
The current moderate long-period northwest swell (320 to 330 degrees) should peak tonight then steadily decline the rest of the work week. A smaller north-northwest swell should provide a boost this weekend. Surf along south facing shores should see a series of small long- period southwest pulses through the weekend. The first pulse peaked today with another small long-period southwest swell possible Friday into the weekend. Additionally, a fetch of strong southwest winds near 10N170W yesterday should bring an increase of short-period energy from the southwest Wednesday into Thursday. East facing shores should remain small through much of the week due to the lack of strong trades upstream of the state.
