Swell Summary

Surf along east facing shores will slowly rise today as swell energy from Tropical Cyclone Kiko arrives. Latest buoy observations from buoy 51004 has started to pick up energy in the 11 to 13 second spectral bands throughout the night. Surf will likely come in below advisory thresholds through today. But, as Kiko moves northwest, a rapid rise of a short lived east swell is expected to fill in, peak potentially at low end High Surf Warning levels Tuesday, before declining through Wednesday. A High Surf Warning for east facing shores will likely be issued this afternoon. Note, peak surf heights will be highly dependent on the track and intensity of Kiko as it nears the state.

A moderate long period south-southwest swell has filled in overnight, likely peak this morning and will slowly decline this afternoon before another reinforcing swell out of the south- southwest is expected on Tuesday. This should help maintain surf near or slightly above the summer average throughout the first half of the week. Additionally, multiple small pules of northwest swell energy will generate small surf along north facing beaches throughout the week.
