✨ You glow, San Diego

We know San Diego has glowing beaches, but recently, they’ve been especially bright. Locals have been reporting neon blue water — a result of the naturally occurring sensation known as bioluminescence. And with some luck, you could catch a glimpse.

What causes bioluminescence?

Despite the color of its light, bioluminescence results from a phenomenon known as “red tides.” According to Scripps Institution of Oceanography, this is caused by a dinoflagellate called Lingulodinium polyedra, a plankton that’s particularly common in Southern California. This organism contains a so-called “sunscreen” that gives it a reddish-brown color.

On sunny days, the plankton gathers near the ocean’s surface, giving it a red hue (hence the name “red tides”). However, the bioluminescent glow results from a chemical reaction that emits a blue light, especially when the plankton is moved around quickly by waves at night.

Did you know? Researchers at Scripps called Lingulodinium polyedra “the Michael Phelps of the plankton world” because it moves so quickly. This speed allows it to develop dense blooms — leading to glowing waters.

If you’re on a quest to see bioluminescence, there have been reports across the San Diego coast this month — including Torrey Pines, Carlsbad State Beach, and Mission Bay. However, the phenomenon could occur at any local beach.

If you want to see the glowing tides here are some things to know:
  • There’s no way to forecast when red tides are coming, though methods are still being researched. However, data suggests events are more common in February through September.
  • Event length is unpredictable, but bioluminescence often lasts one week to one month. If there was a glow yesterday, there’s a good chance of activity today.
  • Bioluminescence is best seen in the dark. Find a beach with little man-made light, and wait about two hours after sunset.
  • The plankton should not be consumed, but generally, it’s not harmful to humans.

News Notes
  • San Diego has installed 100+ Smart Streelights, part of an ongoing effort that will add over 500 security cameras to the city. This license plate-tracking technology was approved by City Council in November 2023, and so far, the city says it’s been used to recover stolen vehicles and identify suspects in crimes.
  • San Diego County has partnered with UC San Diego Health to launch Revive & Survive — an initiative that will help locals learn CPR. The program aims to train 1 million San Diegans to perform the life-saving procedure via free courses led by healthcare workers.
  • Efforts to bring a proposed high-speed transit connection to San Diego International Airport will require at least three more years before a final route can be selected, according to a recent presentation by SANDAG. The agency will spend the rest of this year analyzing data and airport arrival preferences. (San Diego Union-Tribune)
  • Something new is cooking in Clairemont Mesa — Hi Guest Music BBQ, a restaurant that specializes in shaokao (Chinese barbecue). Inside, guests will find a dining area decorated with neon lights and over-sized art, plus a small stage. The eatery is open daily starting at 5 p.m., with performances expected on weekends.

    🏝️ San Diego’s plan to sea changes

    The City of San Diego is working to address rising sea levels by developing a green infrastructure program known as the “Coastal Resilience Master Plan.” This state and federally funded effort is a component of the city’s “Climate Resilient SD Plan” — guidelines to help the city adapt and thrive in a changing climate.

    This blueprint aims to find nature-based solutions that mitigate coastal flooding and erosion while protecting the natural habitats of San Diego’s wildlife. Solutions could include wetland restoration, dune engineering, waterfront park creation, and landward realignment to move the coastline boundary inward.

    City staff will start collecting feedback at community events, including a booth at the Ocean Beach Farmers Market today. More pop-up events, webinars, and workshops will be scheduled in the future, or you can provide input online. A first draft is expected early this year, and the project aims to be completed in 2026.

    The Wrap

    From the editor
    Good morning, San Diego. I can’t believe we’re just about at the end of February. It’s been a rainy month, but it was still full of fun. Some highlights for me were celebrating Lunar New Year at the House of China in Balboa Park, watching five local dogs in “Puppy Bowl XX,” and catching the San Diego Mojo’s first-ever home game.
