Swell Summary
A series of west-northwest to northwest (300-320 degree) swells are expected this week with the first of the series building this afternoon and peaking tonight into Tuesday. Another reinforcing swell is expected on Wednesday, which should maintain advisory level surf along north and west shores through the middle of the week and possibly into Thursday. Another large west-northwest swell is possible on Sunday.
Due to the lack of strong trades, small surf is expected along east facing shores this week. A slight increase is possible Tuesday through the second half of the week due to the light to moderate east to east-southeast trades. Surf along south facing shores should see a small boost on Wednesday as a small south swell fills in and should produce some rideable surf throughout the second half of the week. Select exposures could also see some small wrap from the large west-northwest swells over the next several days.
