WAVE HEIGHT & SURF TEXTURE

Live AI Coastal Briefing

Monday, October 12, is shaping up to be a beautiful day at the coast, with a dominant marine layer bringing 97% cloud cover and a cool temperature of 60°F. This morning's marine layer will typically burn off by late morning, giving way to a lovely day for beach visitors to enjoy a variety of activities. As the day unfolds, we can expect a range of possibilities for surfers, swimmers, runners, and cyclists, with the morning glass window offering ideal conditions for surfers and the afternoon bringing a gentle onshore breeze.



The surf is looking great this morning, with waves at 3.9 feet, or waist to chest high, and a solid beach break that's perfect for longboarding. With warm water conditions at 73°F, boardshorts are the way to go for surfers and swimmers. However, rip current data is unavailable today, so swimmers should be sure to check with the lifeguard on duty before entering the water. Tides are also an important consideration, with low and high tide times available on local charts, and swell data is unfortunately unavailable.



For runners and cyclists, the morning conditions are ideal, with a light wind of 2mph from the NNE and the marine layer providing cool, overcast cover. With a low UV index of 0, there's no need for special sun protection just yet, but as the morning wears on, it's always a good idea to slather on some sunscreen. Air quality is moderate, with an AQI of 62, so sensitive individuals may want to limit their prolonged outdoor exercise. Beach volleyball, paddleboarding, and tennis are all great options for the morning, before the afternoon onshore breeze picks up and makes conditions a bit more challenging.



As the day develops, we can expect the marine layer to burn off, giving way to pleasant coastal conditions. The pressure is at 29.83 inHg, indicating slightly low pressure and a possibility of unsettled conditions, but for now, it's looking like a beautiful day. By midday, the sun should be shining, and as the afternoon develops, the onshore breeze will pick up, bringing a gentle coolness to the coast. Heading into this evening, we can expect a lovely sunset and a peaceful night ahead, making it a great day to get out and enjoy all that the coast has to offer.

About This Coastline

Santa Monica’s central surf zone lies along a busy urban beach where a broad sandy shoreline meets the shifting waves of Santa Monica Bay. It is not a single reef or point break, but a collection of beach-break peaks influenced by sand movement, swell direction and the structures around the pier.

The Vibe

The mood is accessible and energetic. Beginners often take lessons near Bay Street, experienced surfers search for cleaner peaks along the open beach, and the water is shared with swimmers and bodyboarders when conditions are suitable. The setting is unusually public: rides, hotels and downtown streets remain visible from the lineup.

Mornings generally feel most surf-focused, before the beach path and sand fill with visitors. Later in the day, the experience becomes part of the wider Santa Monica scene rather than a dedicated surf enclave.

The Local Anchor

Santa Monica Pier is the dominant reference point, both visually and physically. It divides sections of beach, provides orientation from the water and connects the surf area with one of California’s most recognisable coastal landmarks. South of the pier, Bay Street Beach is associated with lessons and the historic Inkwell area.

Local surf culture also links Santa Monica to Venice and Malibu. Nick Gabaldón, a pioneering Black and Mexican American surfer, learned at Bay Street before making long journeys to surf Malibu, placing this urban beach within a larger story of access and belonging in California surfing.

The Landscape

The seabed is primarily sand, so wave shape and quality change frequently. Winter swell can produce stronger surf and currents, while summer often brings smaller conditions. As on any exposed ocean beach, conditions should be judged on the day and lifeguard guidance followed.

The landscape combines a wide beach, urban bluff, pier structures and a long crescent of bay. Few surf locations place the ocean and city in such immediate dialogue.
