Southern California's December Delight: A Blend of Sunshine and Mildness

Known for its generally pleasant weather year-round, December brings a continuation of this sunshine with a touch of winter's chill. This makes it a popular time for visitors seeking a warm escape.

Average Temperatures and Rainfall

While the specific temperatures can vary slightly based on location within Southern California (coastal areas tend to be cooler than inland valleys), you can generally expect average highs in the low to mid 60s°F (15-18°C) and lows in the upper 40s to mid 50s°F (9-13°C). This is significantly warmer than many other parts of the United States during December.

Rainfall is relatively infrequent in Southern California during December. While some showers are possible, the region experiences a dry season during this time. However, it's always wise to pack a light jacket or sweater, especially for evenings, as temperatures can drop.

Coastal vs. Inland Temperatures

Coastal regions like Los Angeles, Santa Monica, and San Diego tend to be a few degrees cooler than inland areas such as the Coachella Valley or Inland Empire. Coastal areas also experience a stronger ocean breeze that can make it feel slightly cooler, even on sunny days. Expect a bit more temperature variation inland, with warmer days and cooler nights.
