Southern California is for good reason surfing's second home after Hawaii and the base of much of the industry. Famously surfed by Duke Kahanamoku in 1915 these sunshine beaches hold numerous classic set-ups. The degree of swell exposure, to storms from both the North and South Pacific mean year-round swell. Summer is slightly less consistent but still excellent by most standards. In autumn and and early spring the Santa Ana wind brings weeks of offshore conditions. If these combine with south swells then Malibu and Trestles will fire whereas places such as Rincon require a more northerly swell.
From captaining you own vessel to joining a group on a boat trip, boat charters can be a good way to get away from the crowds and reach the best spots that are only accessible by boat.
