Temperatures at California Beaches in April

Share |

Typical temperatures for beaches along the Pacific Ocean in California during the month of April 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.

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.

For the first time in the year, average high temperatures along the California coast break the 70 degrees Fahrenheit (21 degrees Celsius) mark. This month, Avila Beach, Long Beach, Laguna Beach and Santa Cruz typically reach the low 70s during the day.

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.
