Swell Summary

An extra large, long lived northwest swell continues to rise through the day today before declining Wednesday. There is high potential for wave run- up onto vulnerable roadways and coastal areas in the warning areas today. Expect another large northwest swell towards the end of the week reaching High Surf Advisory levels.

Surf along east facing shores remains flat except for areas that are exposed to the northwest swell wrap through Wednesday. South and west facing shores will also see an increase in short- period wind waves today due to the strong onshore winds. A tiny south swell looks to arrive Thursday.
