Water temperature and wave height on the beaches of Los Angeles
Coast and sea characteristics in the Los Angeles area
Beaches and Coastline
- Varied Coastal Terrain: The Los Angeles coastline stretches for approximately 75 miles (120 km) along the Pacific Ocean. It features a mix of wide, sandy beaches, rocky cliffs, and scenic coves. The most popular beaches include Santa Monica, Venice Beach, Malibu, and Manhattan Beach.
- Sandy Beaches: Most beaches are covered in fine, golden sand, making them ideal for sunbathing, beach sports, and leisurely walks. The beaches are wide and spacious, especially in places like Santa Monica and Dockweiler Beach, which also offers a unique experience of beachside bonfires.
Wave and Surf Conditions
- Consistent Surf Breaks: Los Angeles is famous for its surfing culture. Beaches like Malibu Surfrider Beach, Manhattan Beach, and Venice Beach are known for consistent, rideable waves suitable for surfers of all skill levels. Malibu is particularly famous for its long, right-hand point break.
- Wave Heights: Wave heights typically range from 2 to 6 feet (0.6 to 1.8 meters), with larger swells occurring during winter due to storms in the Pacific Ocean. Surf conditions are generally calmer during the summer.
- Tide Variability: The tidal range in Los Angeles is moderate, with high and low tides impacting the size and shape of the beaches. Some beaches, like El Matador Beach, become inaccessible during high tide due to narrow paths and rocky formations.
Water Temperature
- Seasonal Variations: The water temperature varies throughout the year, ranging from 14°C to 20°C (57°F to 68°F). The coldest months are December to March, while the warmest are August to October, thanks to delayed ocean heating from summer sunlight.
- Upwelling Effect: Occasionally, the California Current and upwelling events bring cold, nutrient-rich water to the surface, making the water colder than expected, even in summer.
Marine Life
- Diverse Marine Biodiversity: The coastal waters of Los Angeles are part of the California Current Large Marine Ecosystem, supporting a variety of marine life. Visitors may spot dolphins, sea lions, seals, and occasionally gray whales during their migration (December to April). Tide pools found in rocky coastal areas like Point Dume are home to crabs, sea anemones, and small fish.
- Kelp Forests: Just off the coast, kelp forests thrive in the nutrient-rich waters, providing a unique marine habitat for fish, invertebrates, and seabirds. These underwater forests are important for maintaining marine biodiversity.
Sea Conditions and Currents
- California Current: The cold California Current runs southward along the coast, bringing cooler water from the north and affecting water temperatures and weather patterns.
- Rip Currents: Rip currents are common, especially near jetties, piers, and sandbars. These powerful, narrow water channels pull swimmers away from shore. Lifeguards frequently warn beachgoers about rip currents, especially during rough surf conditions.
- Water Clarity: Water clarity varies depending on weather and ocean activity. During calm, sunny days, the water is clearer, but after storms, it can appear murky due to runoff from the Los Angeles River and other water outlets.
Weather and Sea Breezes
- Onshore Winds: The Los Angeles coast experiences a steady flow of onshore winds, especially in the afternoon, which provides natural cooling for beachgoers. This also contributes to the "June Gloom" phenomenon, where the coastal marine layer creates cloudy, overcast skies that typically clear by noon.
- Air and Sea Breezes: These breezes help regulate coastal temperatures, keeping beach areas cooler than inland Los Angeles, especially during hot summer days.
Water Safety and Recreational Activities
- Beach Safety: Lifeguard towers are stationed along most of Los Angeles' popular beaches to ensure swimmer safety. Rip current warnings are posted when necessary.
- Water Sports and Activities: The calm waters and consistent waves are ideal for surfing, paddleboarding, boogie boarding, and kayaking. Sailing and yachting are popular, especially in Marina del Rey, one of the largest man-made marinas in the U.S. Scuba diving and snorkeling are available at select locations, especially around the Channel Islands off the coast of Los Angeles.
Environmental Concerns
- Water Pollution: After heavy rain, water runoff from the Los Angeles River can lead to temporary pollution at beaches. Signs are posted to warn visitors to avoid swimming near river mouths after storms.
- Beach Cleanup Efforts: Regular beach cleanups are conducted by organizations like Heal the Bay to protect marine life and maintain clean beaches.
The coast of Los Angeles is iconic, known for its scenic beauty, vibrant beach culture, and access to diverse marine life. From world-famous surfing spots to serene coves and tide pools, the Los Angeles coastline is a prime location for both relaxation and adventure.

Climate characteristics of Los Angeles
Los Angeles has a Mediterranean climate (Köppen classification: Csa) characterized by mild, wet winters and hot, dry summers. Due to its location along the Pacific Ocean and its diverse topography, the climate can vary slightly depending on the proximity to the coast or the inland valleys.
Temperature: Los Angeles experiences warm to hot temperatures throughout the year. Coastal areas remain cooler due to the marine breeze, while inland valleys can get significantly warmer. Average high temperatures range from 18°C (64°F) in January to 29°C (84°F) in August, with occasional heatwaves pushing inland temperatures above 35°C (95°F).
Seasons: Unlike areas with four distinct seasons, Los Angeles has two primary seasons:
- Dry Season (April to October): Warm, sunny, and dry weather prevails, with minimal rainfall. Clear skies and high UV exposure are typical.
- Wet Season (November to March): This period sees the majority of the city's annual rainfall, though it is still relatively dry compared to other regions. Winter storms can bring rain, but snow is extremely rare, occurring only in nearby mountains.
Rainfall: Annual precipitation in Los Angeles is around 375 mm (15 inches), with most of it falling during the wet season. Rain typically comes in short, intense bursts, sometimes causing flash floods in low-lying areas. Summers are mostly rain-free.
Humidity: The city experiences moderate humidity, which is highest in the mornings due to coastal fog. Inland areas have lower humidity and experience a drier climate. Coastal areas often experience "marine layer" fog in the early morning, especially in spring and early summer, but it usually burns off by midday.
Winds: Los Angeles is known for its Santa Ana winds, which are hot, dry winds that blow from the desert toward the coast, usually in the fall and winter. These winds increase the risk of wildfires in the region.
Sunshine: Los Angeles is famous for its abundant sunshine, with over 284 sunny days per year. This makes it one of the sunniest major cities in the United States. Sun protection is necessary year-round.
Coastal Influence: Areas near the coast are cooler and more humid due to the influence of the Pacific Ocean. Ocean breezes help moderate temperatures, while areas farther inland experience larger temperature fluctuations.
Climate Variations by Area:
- Coastal Areas (e.g., Santa Monica, Venice): Cooler temperatures, marine fog, and ocean breezes.
- Inland Areas (e.g., San Fernando Valley, San Gabriel Valley): Warmer summers, colder nights, and drier air.
- Mountain Areas (e.g., Angeles National Forest): Colder temperatures, especially at night, with occasional snowfall in winter.
The climate in Los Angeles allows for outdoor activities and tourism year-round. While it is known for its sunshine and warmth, the Santa Ana winds and occasional heavy rains during winter require some seasonal awareness.
