The city’s Mediterranean climate means mild winters, but the coastal influence keeps things comfortable rather than harsh. The following quick snapshot highlights the main factors you’re likely to encounter when checking the weather in LA in January:
- Average daytime highs: generally in the range of 18–21°C (64–70°F), with occasional warmer days reaching into the low 70s (low 20s°C) on the best afternoons.

What to expect: temperatures, rainfall and sea conditions
Temperature ranges in January
The temperature in January varies across the city due to microclimates created by hills, ocean proximity, and urban density. In the morning, expect cooler temperatures, especially on clear nights when a thin mist can settle in valleys. By midday, the sun warms surfaces and people often enjoy comfortable warmth. In practice, daytime highs of 18–21°C are common, with a few days pushing higher into the low 20s. Night-time temperatures often dip to around 7–12°C, which makes a warm layer essential for evening outings.
For travellers seeking precise planning, a typical day might look like this: a crisp start with cool air and a bright sky, a mild afternoon where long-sleeve layers are comfortable, and an evening that suggests a cosy jacket and perhaps a scarf for coastal breezes. Those staying in hillside or inland pockets may notice cooler nights and a tendency for temperatures to drop more quickly after sunset.
Rainfall and humidity: how often does it rain in January?
Rain in January is not uncommon, but LA’s rains tend to be light-to-moderate and spread across several days rather than resulting in continuous downpours. The city can experience extended dry spells between rain events, punctuated by periods of drizzle or brief showers. Humidity tends to rise a little during wetter spells, and dawn or dusk can carry a cool, damp feel. For anyone tracking the weather in LA in January, the pattern to watch is a few rainy days interspersed with stretches of dry, bright weather that makes the city feel jubilantly alive with colour and light.
Sea temperature and coastal conditions in January
The sea remains cool in January, often around 14–16°C (57–60°F). Surfers and ocean enthusiasts will find winter waves can be consistent along certain breaks, though water temperatures are not as forgiving as the summer months. Coastal fans should prepare for a bracing dip or opt for a coastal stroll rather than a long swim. Winds along the shoreline can vary, with stronger gusts possible on days when the Pacific winds pick up after a rain front. For family beach days, late morning to early afternoon typically provides the most reliable sun and warmth, particularly on clear December-to-February days, a pattern that can be enjoyed in January as well.
Regional variations: how the weather differs across LA
Santa Monica and Venice Beach: ocean air and coastal cool
The coastal strip between Santa Monica and Venice tends to be the coolest in terms of air temperature, thanks to constant onshore breezes. Mornings can feel fresh, with sea fog possible on mistier days. By midday, temperatures often climb into the upper teens or low 20s, making beached promenades and outdoor cafés a joy when the sun shines. The sea air also means a higher chance of light rain with damp pavements after a shower, so waterproof footwear is sensible if you’re wandering along the boardwalk. The mellow climate makes these areas ideal for a January stroll, photography sessions, or a café stop with sea views.
Downtown LA and central districts: urban warmth and air movement
Downtown and adjacent neighbourhoods typically enjoy a slightly warmer microclimate on sunny days, thanks to urban heat and neglectable altitude. However, the urban canyon effect can amplify wind speeds on exposed corridors, particularly after a cold front passes. Expect cooler mornings and relatively mild afternoons, with a higher chance of cloud cover or light drizzle in the early part of January. The advantage here is easy access to museums, galleries, theatre, and riverfront parks with comfortable, walkable routes.
Pasadena, the San Gabriel Valley and hillside enclaves
Valley cities like Pasadena can feel a touch cooler at night than the coast, with more pronounced temperature swings between day and night. Hillside areas can experience even lower overnight temperatures and a greater possibility of fog or frost in the more enclosed valleys. January light in the hills is crisp and clear on high-pressure days, offering spectacular morning vistas and long afternoon shadows, perfect for photography and mild hikes with superior city views.
Hollywood Hills and Griffith Park: elevation and exposure
Elevated areas see stronger breezes and cooler nights. Griffith Park’s higher terrain can feel brisk, especially in the early mornings and late evenings. On the right days, you’ll enjoy bright sunshine that brings warmth to the trails, while the breeze keeps temperatures from rising too high. It’s a glorious time for outdoor enthusiasts who want more of a wintery outdoor feel without the harsh conditions that many other cities experience in winter.
Sea and sand: January beach experiences
Despite January’s cooler air, the beaches of LA remain a favourite for locals and visitors. The water is not warm, but it’s usually tolerable for those who know to dress appropriately. Surfing remains popular during winter, with several well-known breaks offering reliable conditions for intermediate surfers. If you simply want a seaside stroll, a January day with sunshine can feel almost tropical by comparison to northern winters. Pack a light jacket for shoreline winds, a hat for sun protection when the sky is clear, and waterproof footwear for damp promenades after rain.
Sunshine, cloud cover and wind across January
LA’s January sunshine is a delightful constant, but it’s never guaranteed. Clear, bright days are common, and blue skies can dominate the late morning to early afternoon window. Cloud cover is more frequent in the mornings, when coastal fog or low cloud can roll in, especially over the ocean and through the valleys. Winds peak along the coast and sometimes in the hills, particularly after a front moves through. For those chasing the best light for photography or outdoor activities, the mornings following rain or fog can offer dramatic contrasts and soft, atmospheric conditions that are ideal for captures of the city’s iconic silhouettes.
Practical packing: what to wear in January
January calls for a versatile wardrobe that accommodates coastal cool, urban warmth, and the occasional wet spell. Here are practical guidelines to ensure you’re prepared for most conditions:
- Layered outfits: base layers, a warm mid-layer, and a waterproof outer layer. A light down jacket or fleece is often sufficient for most daytime activities.
- Waterproof footwear: essential for damp streets after rain or for coastal strolls where spray and sea mist can dampen shoes.
- Smart-casual options: evenings in restaurants or theatres may require a slightly smarter look, so consider a smart jacket or blazer as part of your layers.
- Accessories: a scarf, lightweight gloves for the early morning, and sunglasses for bright days are sensible inclusions.
- Beachwear alternatives: if you plan to brave a winter dip or a brisk beach walk, pack a swimsuit or towel as a practical courtesy item.
January activities: what to do when the weather in LA in January
With comfortable temperatures and manageable rainfall, January opens a broad array of activities. Here are some ideas that align well with the season:
- Explore museums and galleries: the cooler days are perfect for indoor experiences in the city’s world-class institutions, such as the Getty, LACMA, and the Broad, or for exploring the historic core on urban walks.
- Hike in the hills: Griffith Park, Runyon Canyon, and the San Gabriel foothills offer scenic trails with city views. Pack water and appropriate footwear for elevation changes and potential muddy patches after rain.
- Coastal strolls: a bright morning along Santa Monica Pier or Venice Beach can be uplifting; the sea breeze adds a refreshing energy to your day.
- Live events and theatre: January is a great time to catch new theatre productions, concerts, and film screenings that flourish in the city’s vibrant cultural scene.
- Beachside cafés and markets: after a crisp morning, many cafes along the coast offer sunlit seating where you can enjoy a relaxed lunch with views of the ocean.
January travel tips: navigating crowds, deals and transport
January is typically less crowded than the peak summer months, making it a comfortable time to explore.

- Use public transport where possible: Los Angeles’ metro system offers a practical way to reach major venues and beaches, avoiding traffic during busier times.
