Making the most of the West Coast leg of wife Gwen Stefani‘s summer tour with No Doubt, rocker Gavin Rossdale frolics in the surf with the couple’s 11-month-old Zuma Nesta Rock on Thursday.

Gwen was also on hand yesterday (see extended post) as the family-of-four — including Zuma’s big brother, 3-year-old Kingston James McGregor — spent their afternoon on the beach at Dana Point, Calif.

Tonight Gwen plays the first of four sold out shows with No Doubt at the Verizon Wireless Amphitheater in Irvine, Calif.
