Southern California Surf Forecast (Wed, July 27, 2011)

Southern California surf forecast as of Wednesday, July 27: A new SSW swell fills Thursday into Friday, with a smaller SSW reinforcement hitting Sunday into Monday.

(1) 20-second South forerunners are expected late Wednesday. Keep an eye on the real-time swell period reports from stations such as Mission Bay and Camp Pendleton Nearshore, which are a bit more sheltered from short-period influences.

(2) The South swell builds through Thursday, with wave heights peaking late Thursday into Friday. Swell heights are expected to reach 3.1 feet, and hold steady in the 3-feet at 15-seconds range through Friday, before tapering off into the weekend.

(3) More long-period South-Southwest forerunners begin to arrive on Saturday. As the existing SSW (193°) swell fades over the weekend, expect a new SSW (199°) component to build Saturday into Sunday. Because the long-period forerunners will be filling underneath a more dominant swell, don’t expect to see them reflected in the real-time primary swell reports.

(4) Expect a slight boost in wave height late Sunday into Monday, as the SSW reinforcement peaks. This swell will not be as powerful as the Thursday/Friday pulse, but will provide energy in the 2-feet at 15-second range at its peak.
