Temperatures at California Beaches in May





Typical temperatures for beaches along the Pacific Ocean in California during the month of May are listed below. The tables give monthly averages of daily maximum and minimum air temperatures for each location and, where available, the month's average ocean temperature.

While the days get warmer in May, this month brings the coolest water of the year to many places along the northern California coast. In fact, Fort Ross State Park in May achieves the coldest average ocean temperature for the state's entire coast, as the water there usually drops down to 49 degrees Fahrenheit (9 degrees Celsius).

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.

The high and low air temperatures are normals for the years 1981 to 2010. Temperatures for the two places without climate normals, Anacapa Island and Avila Beach, are instead averages for the years that weather data were collected. Ocean temperatures are also averages of all the years with measurements.

Often the location of stations that measure weather and those that measure ocean water temperature don't match. For beaches with climate but no ocean data, a nearby location, where available, is used here. So the ocean temperature listed for San Diego is from La Jolla. Other substitutions are Los Angeles for Long Beach, Port Hueneme for Oxnard, Pacific Grove for Monterey, Fort Point for San Francisco, Trinidad for Eureka, and Mendocino for Fort Bragg.
