The best Months to dive in Southern California

Diving in Southern California is a year-round activity, thanks to its mild climate and diverse marine environments. Water temperatures range from 15°C–20°C/59°F–68°F. Visibility typically varies between 3 to 9 meters/10 to 30 feet, influenced by weather conditions and water currents.

Winter and spring can bring rougher seas and lower visibility due to increased wind and swell. However, summer and fall often offer calmer waters and improved visibility, making these seasons more favorable for diving. Despite the seasonal variations, diving is generally feasible throughout the year, with periods of reduced comfort rather than complete inaccessibility.
