Temperatures at California Beaches in December





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

Although this is one of the coolest months of the year along California's beaches, several spots typically have temperatures reaching into the mid-60s Fahrenheit during the day. Indeed, the state's entire coast normally gets above 50 degrees F (10 degrees Celsius) each day.

Klamath in December has the coldest nights of the year for any coastal Californian town, where temperatures usually drop to 36 degrees F (2 °C).

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.
