Swell Summary
Small surf along south-facing shores will continue through Tuesday before a series of long-period S to SSW swells are expected to arrive Wednesday through the weekend. The first pulse will gradually fill in tonight into Wednesday out of the southwest, followed by larger south- southwest swells Friday into the weekend. As a result of these swells, surf will gradually trend upward through the week beginning Wednesday and could approach advisory thresholds by the weekend.
Surf along east-facing shores should see an increase during the second half of the week as the trades strengthen and the remnants of Tropical Storm Norbert move through the islands. Flat to tiny surf along north facing shores is expected through the forecast period.
