Temperatures at California Beaches in March
Typical temperatures for beaches along the Pacific Ocean in California during the month of March 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.
Average temperatures in March along the Pacific Ocean in California range from nighttime lows of 38 degrees Fahrenheit (3.3 degrees Celsius) at Klamath to daytime highs of 69 °F (21 °C) at Avila Beach.

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.
