Live AI Coastal Briefing

This morning, Thursday, April 9, we're waking up to a classic coastal scene, with a dominant marine layer bringing 100% cloud cover and very high humidity. This marine layer typically burns off by late morning, revealing a beautiful day for beach visitors, with plenty of opportunities for surfing, running, cycling, and other outdoor activities. As the day unfolds, we can expect a range of exciting conditions for all kinds of sports and fitness enthusiasts.



The ocean is looking inviting, with surf conditions at a solid 3.0 feet, waist to chest high, and a great beach break for experienced surfers. With a water temperature of 66°F, a spring suit will be comfortable for most, while a full wetsuit may be preferable for longer sessions in the water. We're seeing standard conditions for swell, and while rip current risk is low, it's always important to exercise standard beach safety precautions. Be sure to check your local tide chart for low and high tide times, and plan your water activities accordingly.



For runners and cyclists, the morning conditions are ideal, with a gentle 3mph wind from the ENE and the marine layer providing cool, overcast cover. With a low UV index of 0, you won't need special protection just yet, but be sure to slather on the sunscreen as the morning wears on and the sun starts to break through. Moderate air quality means sensitive individuals should limit their prolonged outdoor exercise, but there's still plenty of opportunity for beach volleyball, paddleboarding, and tennis, especially in the morning window before the onshore breeze picks up. Take advantage of the calm conditions to get your outdoor fitness fix before the afternoon winds arrive.



As the afternoon develops, we can expect the marine layer to have burned off, revealing a beautiful sunny day, although the pressure at 29.90 inHg indicates slightly low pressure, which could lead to some unsettled conditions. Nonetheless, it's shaping up to be a fantastic day to get outdoors and enjoy all that our coastal city has to offer, from surfing and cycling to beach volleyball and paddleboarding. So why not grab your board, your bike, or your running shoes, and make the most of this lovely spring day – we're looking forward to a wonderful day ahead, and we hope you are too.
