HIGH SURF ADVISORY FOR SOUTH FACING SHORES

Swell Summary

The High Surf Advisory (HSA) has been extended through Friday as a long-period south swell is forecast to peak tonight, with advisory level surf likely continuing into Friday as it begins to trend down. Friday night, it is possible that surf briefly falls below advisory criteria before another reinforcing long-period south swell arrives for Saturday and may push surf back up to advisory level. Regardless of whether there is a brief break or advisory level surf is maintained, there is potential for the HSA to be extended into the weekend. However, this next southerly pulse looks to be somewhat shorter period and lower energy than the last. The south swell will then slowly decline through the first half of next week.

Surf along east-facing shores will remain rough and choppy, supported by strong easterly trade winds combined with a small, medium-period east swell generated by former TC Elida. The latter swell fades through Friday while trade wind swell continues. This weekend, larger surf generated by Hurricane Fausto is possible and could bring advisory level surf along east facing shores by late Sunday into early next week.

Surf along north-facing shores will remain at flat to tiny levels through the weekend.
