Swells generated in the north Pacific Ocean during winter months seasonally create large waves and surf in Southern California. The CDIP model (Coastal Data Information Program) illustrates how west swells travel through the Santa Barbara channel with the energy focused on Ventura.
The January 9 swell had 14 ft waves at 15 seconds from a 280 degree westerly direction. High tide was 5.1 ft at 10:26 am.
The January 18 swell had more energy with 16 ft at 17 seconds from 285 degrees, and 6.1 ft high tide at 6:36 am.
Although the swell dropped during the 6.8 ft "King Tide" on January 20, similar overtopping was observed along the promenade in Ventura.
The following is a collection of photos from these high surf, high tide events.
Ventura's Pierpont community suffered minor flooding with both these events, with wave runup into the streets in areas without dune protection.

The Managed Retreat project functioned as designed, with eroded sand exposing the buried cobble berm, and minor overtopping into the foredune area.

Although the swell and tide were higher on the 18th, driftwood and debris from the Ventura river reduced wave runup in the managed retreat zone.
