As winter grips much of the country, many travelers are already planning escapes to warm places to visit in December California. From sun-drenched deserts to breezy coastal cities, the Golden State offers plenty of destinations where daytime warmth and outdoor adventures continue well into the holiday season. As of mid-October 2025, several top locations are preparing for an influx of visitors eager to trade heavy coats for light jackets and flip-flops.
Whether you’re after desert calm, cultural events by the beach, or a relaxed family getaway, December in California delivers some of the most comfortable winter weather in the country.
Why California Stays Warm in December
California’s unique geography creates major temperature contrasts during the winter. While the northern mountains cool down rapidly, the southern coast and inland deserts remain pleasantly warm. December temperatures in many southern and desert regions often sit in the upper 60s to low 70s °F during the day, with clear skies and minimal rainfall. These conditions make it ideal for sightseeing, hiking, and enjoying outdoor festivities without the intense heat of summer or the crowds of peak travel months.
The best warm destinations tend to cluster in Southern California and the low-lying desert valleys, offering reliable sunshine, mild afternoons, and a relaxed seasonal pace.
Palm Springs and the Coachella Valley
Few destinations are as consistently warm in December as Palm Springs. Nestled in the Coachella Valley, this desert city typically enjoys daytime highs around 70 °F with crisp, clear skies. Evenings are cooler but comfortable with a light sweater.
Why it stands out in December:
- Warm, dry weather ideal for golf, spa retreats, and poolside lounging
- Unique mid-century modern architecture tours
- Scenic rides on the aerial tramway with panoramic desert views
- Nearby national parks for daytime excursions
Palm Springs also hosts festive light displays and seasonal markets during December, creating a lively but relaxed holiday atmosphere without winter chills.
San Diego and the Southern Coast
San Diego is one of California’s most dependable warm spots in December. Daytime temperatures usually range from the mid-60s to low 70s °F, with cool evenings and very little rain. Its coastal location means visitors can enjoy a mix of beaches, parks, and urban experiences in one trip.
December highlights in San Diego:

Nearby beach towns like La Jolla, Del Mar, and Coronado provide quieter escapes while maintaining the same mild weather. Many hotels offer off-season packages in December, making it a smart time for budget-conscious travelers.
Los Angeles and Surrounding Areas
Los Angeles offers a combination of cultural attractions and warm coastal days during December. Temperatures typically hover around the upper 60s °F, and while mornings and evenings can be cool, the afternoons are ideal for sightseeing without the summer heat.
Top December activities in the Los Angeles area:

Within driving distance, Santa Barbara offers another mild coastal option, with pleasant beach walks and a slower pace ideal for couples and families.
Southern Orange County and San Clemente
For travelers looking for a quieter beach town experience, Southern Orange County stands out. San Clemente and surrounding coastal communities maintain daytime highs in the low 60s °F through December. While the ocean water can be chilly, the air is often mild enough for comfortable beach walks, surfing with wetsuits, or enjoying oceanfront dining.
This stretch of coastline is less crowded during the winter, making it ideal for those who prefer relaxed getaways without tourist congestion.
Joshua Tree National Park and Desert Adventures
While desert nights can be quite cold, Joshua Tree’s daytime temperatures often sit in the mid-60s to low 70s °F in December. This makes it a perfect time for hiking, rock climbing, and exploring the park’s unique landscape. Trails that are scorching in summer become pleasant in winter, and the clear skies create incredible conditions for photography and stargazing.
Many travelers base themselves in Palm Springs or Yucca Valley, taking day trips into the park to enjoy the warmth of daylight hours before retreating to cozy accommodations in the evenings.
