If you’re planning a trip to Los Angeles in December, you’re probably wondering about the LA weather in Dec. Here’s the thing: December in LA is a unique blend of mild temperatures and occasional rain, making it a month of contrasts. I’ve spent several Decembers in LA, and I’ve learned that while it’s not as sunny as summer, it’s far from the harsh winters you’d find in other parts of the country. The average high hovers around 68°F (20°C), while nights can drop to a cooler 50°F (10°C). Rain is possible, but it’s usually sporadic, so packing a light jacket and an umbrella is a smart move.
Understanding LA’s December Climate
December marks the beginning of LA’s rainy season, though it’s nothing like the downpours you’d see in Seattle or New York. In my experience, the rain tends to come in short bursts, leaving plenty of dry days to explore. The humidity is relatively low, which means even on cloudy days, it doesn’t feel oppressive. One thing to note is that the LA weather in Dec can vary depending on where you are in the city. Coastal areas like Santa Monica tend to be cooler and foggy, while inland spots like Pasadena are slightly warmer.
What to Expect: Temperature and Rainfall
Temperature-wise, December in LA is mild but not hot. Daytime temperatures rarely exceed 70°F (21°C), and nights can feel chilly, especially if you’re not used to the desert-like dryness. Rainfall averages around 2-3 inches for the month, but it’s unpredictable. I’ve had Decembers with barely a drop and others with a few rainy days in a row. The key is to be prepared for both sunshine and showers.
Daily Averages
Here’s a quick breakdown of what you can expect:
- Highs: 65°F to 70°F (18°C to 21°C)
- Lows: 48°F to 52°F (9°C to 11°C)
- Rainy Days: 5-7 days on average
How to Dress for LA’s December Weather
Dressing for LA weather in Dec can be tricky because of the temperature fluctuations. Layers are your best friend. I usually start with a t-shirt, add a sweater or light jacket, and carry a scarf for cooler evenings. Comfortable shoes are a must, especially if you plan to explore outdoor attractions like Griffith Observatory or the Hollywood Walk of Fame. And don’t forget sunglasses—even on cloudy days, the sun can be bright.
💡 Note: While LA doesn’t get snow, the surrounding mountains might. If you’re planning a day trip to Big Bear or Mount Baldy, pack warmer clothing.
Best Activities for December in LA
December is a great time to visit LA, not just because of the weather but also the holiday vibe. The city comes alive with festive events like the Marina del Rey Holiday Boat Parade and ice skating at Pershing Square. Personally, I love strolling through the holiday lights at the Grove or exploring the outdoor markets. If you’re a beach lover, don’t write off the coast—Venice Beach and Santa Monica Pier are still enjoyable, even if it’s too cold for swimming.
Indoor vs. Outdoor Activities
If the weather turns rainy, LA has plenty of indoor options. Museums like the Getty Center and the Broad are excellent choices. I’ve spent many a rainy afternoon exploring their collections. For families, the California Science Center and the Natural History Museum are great alternatives. And of course, there’s always shopping—whether it’s high-end boutiques on Rodeo Drive or vintage finds in Silver Lake.
