Swell Summary

Swells from Hurricane Lowell has filled in and will remain elevated above High Surf Advisory conditions through Friday. The swell will gradually veer from southeast towards the southwest early next week. While, the forecast for swells and seas for next week will highly depend on the eventual track and intensity of Lowell, confidence is beginning to increase for the potential of extra- large surf (exceeding warning levels) along south and western exposures early next week. Coinciding also with monthly high tides, this will create the potential for impacts to harbor entrances, channels, as well as coastal properties and infrastructure including roadways.

A large, medium-period east swell from Hurricane Karina will steadily fill in Friday into the weekend and will likely produce high end advisory level surf or warning level surf along east facing shores by this weekend.
