The best Months to dive in Northern California

Northern California offers year-round diving opportunities, although conditions can vary significantly by season. During the summer, water temperatures typically range from 13°C–16°C/55°F–61°F, while winter temperatures can drop to 10°C–12°C/50°F–54°F. Visibility is often best in the fall, reaching up to 15 meters/49 feet, but can be reduced to as low as 3 meters/10 feet in spring due to plankton blooms.

Weather factors like coastal winds and currents significantly affect diving conditions. The region experiences higher winds and stronger currents in spring, which can impact dive plans. While diving is possible throughout the year, late summer and early fall are generally considered the most favorable periods due to calmer seas and clearer visibility, making them ideal for planning dives.
