Ocean Temperatures Along the California Coast in Spring

Share |

Average water temperatures of the Pacific Ocean along the California coast during spring are listed below. You can jump to a separate table for each region of the state: Southern Coast, Los Angeles Area, Central Coast, San Francisco Area and Northern Coast.

Ocean spring temperatures range from an average of 60 degrees Fahrenheit (16.5 degrees Celsius) in southern California to 50 degrees F (10 C) off the state's northern beaches.

These coastal water temperatures are averages compiled by the National Oceanographic Data Center. Actual ocean temperatures do vary from year to year depending upon the weather and the flow of ocean currents.

The Pacific Ocean warms rapidly in spring along much of the California coast. The sea heats up especially fast in the sheltered waters at Newport Beach and at Alameda in San Francisco Bay.

A few places follow a different trend, though and register their coldest ocean temperature of the year during April and May. Spring brings the year's coolest water to Point Mugu, Point Lobos, Bodega Bay and Fort Ross.

Spring, in fact, is when the ocean at Fort Ross reaches the lowest average temperature for the state's entire coast. Fort Ross is the only place in California where the average ocean temperature drops below 50 degrees F.
