Los Angeles weather in November 2026 transitions the region from warm autumn conditions into cooler, late-fall atmospheric patterns characterized by average daytime highs in the low 70s Fahrenheit, overnight lows dropping into the mid-50s, and the increasing likelihood of early-season Pacific storm systems bringing rainfall to Southern California.
Understanding Los Angeles weather patterns for November 2026 requires looking beyond simple temperature averages to examine historical meteorological data, precipitation forecasts, microclimate variations across the Los Angeles basin, and practical strategies for outdoor activities, travel, and seasonal preparation. Whether planning travel to Southern California or managing local daily operations, knowing what to expect from the atmospheric conditions during this late autumn month ensures proper preparation.
Historical Climate Baseline and November 2026 Meteorological Outlook
To understand what November 2026 brings to the Los Angeles area, meteorologists analyze decades of historical climate data compiled by the National Weather Service (NWS) and the National Centers for Environmental Information (NCEI). November marks the definitive shift from dry autumn warmth to the start of the Southern California wet season, although dry spells and Santa Ana wind events frequently punctuate the month.
The climatological baseline for downtown Los Angeles and surrounding coastal and inland valleys establishes clear expectations for temperature ranges, precipitation probabilities, and daylight hours throughout the month.
- Average Daily Maximum Temperature: 70°F to 74°F (21°C to 23°C), typically peaking during the early afternoon hours.
- Average Daily Minimum Temperature: 52°F to 56°F (11°C to 13°C), occurring during the predawn hours.
- Average Monthly Rainfall: 1.0 to 1.5 inches across the urban basin, heavily concentrated in episodic storm events rather than steady drizzle.
- Average Sea Surface Temperature: 61°F to 64°F (16°C to 18°C), making ocean activities brisk.
- Average Daylight Hours: Approximately 10.5 hours, with sunrise occurring around 6:30 AM and sunset nearing 5:00 PM following the end of Daylight Saving Time.
Atmospheric Drivers Affecting November 2026
Long-range forecasting models for late 2026 point toward neutral-to-mild La Niña or ENSO-neutral conditions in the Pacific Ocean. For Southern California, this typically translates to near-normal precipitation totals, though winter weather patterns can shift rapidly. Jet stream positioning remains the primary driver of whether Pacific storm tracks dip far enough south to impact the Los Angeles basin or remain deflected toward the Pacific Northwest.
Microclimate Variations Across the Los Angeles Basin
Los Angeles is famous for its diverse microclimates. Weather conditions in November can vary dramatically depending on whether you are standing on the Santa Monica coastline, downtown in the concrete urban core, or inland toward the San Fernando and San Gabriel Valleys.
| Region / Zone | Typical November High (°F) | Typical November Low (°F) | Primary Meteorological Influences |
|---|---|---|---|
| Coastal Zone (Santa Monica, Malibu, Long Beach) | 68°F - 71°F | 55°F - 58°F | Marine layer moderation, ocean breeze, lower diurnal temperature swings. |
| Downtown & Central LA (USC campus, Hollywood, Silver Lake) | 72°F - 75°F | 53°F - 56°F | Urban heat island effect, protected from immediate marine inversions. |
| San Fernando & San Gabriel Valleys (Pasadena, Burbank, Van Nuys) | 73°F - 77°F | 48°F - 53°F | Greater diurnal swings, susceptible to rapid cooling and Santa Ana winds. |
| Mountain Foothills (Altadena, Sylmar, Claremont) | 67°F - 72°F | 45°F - 50°F | Higher elevation cooling, primary corridor for offshore wind acceleration. |
The Marine Layer and Coastal Inversions
While summer marine layers are a daily fixture, November brings a modified marine layer dynamic. Low stratus clouds and morning fog still form along the coast overnight but typically burn off more quickly under a lower November sun. When high-pressure systems build over the Great Basin, however, the marine layer is suppressed entirely, clearing the skies and setting the stage for offshore wind events.
Santa Ana Winds and Wildfire Risk in November 2026
One of the most defining and dramatic features of Los Angeles weather in the autumn months is the arrival of the Santa Ana winds. These strong, extremely dry offshore winds originate from high-pressure air masses over the Great Basin (Nevada and Utah) and accelerate as they force their way southwestward through mountain passes and canyons into the Los Angeles basin.
Mechanics and Impacts of Santa Ana Wind Events
- Temperature Spikes: As air descends from high elevations to sea level, it compresses and warms adiabatically, often pushing daytime temperatures well into the 80s even in late November.
- Humidity Plunges: Relative humidity levels frequently drop below 10% to 15%, creating desiccated vegetation and extreme dryness.
- Red Flag Warnings: The combination of high wind gusts (frequently exceeding 40 to 60 mph in mountain passes) and ultra-low humidity triggers NWS Red Flag Warnings and extreme wildfire danger across the region.
- Air Quality Effects: Santa Ana winds can sweep dust and particulate matter across the basin, occasionally degrading air quality and reducing visibility.
Rainfall, Storm Systems, and Hydrological Outlook
November represents the official opening window for the Southern California rainy season. While September and October are bone-dry, November averages its first substantial precipitation events of the cool season.
Understanding Southern California Precipitation
Precipitation in Los Angeles does not fall in gentle, persistent April showers. Instead, it arrives in dramatic, concentrated atmospheric river events or cold front passages. A single heavy storm in November can drop an inch or two of rain in a 24-hour period, accounting for the entire month's historical average.
- Flash Flood Potential: Burn scars from earlier wildfire seasons remain vulnerable to mudflows and debris flows when heavy rainfall hits steep canyon slopes.
- Urban Runoff: The concrete-lined Los Angeles River and local storm drain networks rapidly channel urban runoff into the Pacific Ocean, occasionally prompting bacteria advisories at local beaches following the first major storms of the season.
- Snowfall in Local Mountains: While snow is virtually nonexistent in the Los Angeles basin, peaks like Mount Baldy (elevation 10,064 feet) in the San Gabriel Mountains frequently receive their first dusting of winter snow by late November.
What to Wear and How to Pack for Los Angeles in November 2026
Packing for a trip to Los Angeles in November requires a layered wardrobe approach. Visitors often make the mistake of assuming Southern California weather is perpetually hot, only to find themselves shivering during chilly evenings when temperatures drop rapidly after sunset.
Essential Packing List Recommendations
- Layering Essentials: Bring light sweaters, cardigans, and fleece jackets for evenings and early mornings.
- Outerwear: A medium-weight, water-resistant jacket or trench coat is vital for rainy days or breezy coastal walks.
- Daytime Casual: T-shirts, light long-sleeve shirts, and comfortable jeans or chinos for daytime outings when temperatures sit comfortably in the low 70s.
- Footwear: Comfortable walking shoes or sneakers; waterproof boots are generally unnecessary unless navigating heavy storm puddles or hiking muddy trails.
- Sun Protection: Even though it is late autumn, the California sun remains strong. Sunglasses, a hat, and sunscreen are mandatory for outdoor activities.
Outdoor Activities, Travel Planning, and Event Scheduling
November is widely considered one of the best months of the year to explore Los Angeles. The oppressive heat of the summer months has dissipated, tourist crowds at major attractions have thinned out, and the city offers a comfortable climate for both urban exploration and outdoor recreation.
Recommended Activities and Ideal Conditions
- Hiking: Trails in Griffith Park, Runyon Canyon, and the Santa Monica Mountains offer crisp, clear air and sweeping panoramic views, particularly right after a storm clears the smog.
- Theme Parks: Universal Studios Hollywood and Disneyland experience lower wait times on weekdays during November (excluding the Thanksgiving holiday week), paired with pleasant weather that prevents overheating.
- Sightseeing: Walking tours of Downtown LA, architectural visits in Hollywood, and strolls along the Venice Canals or Santa Monica Pier are exceptionally comfortable under mild autumn skies.
- Beach Visits: While sunbathing and swimming are reserved for hardy locals or visitors wearing wetsuits due to 60-degree ocean temperatures, beach walks and sunset viewing remain premier experiences.
