San Clemente had strong bioluminescence due to "red waves" in May 2020, but it's gone now and currents are tough to track.

I've been on a night time bioluminescence kayak tour in Tomales Bay, a bit more than an hour north of San Francisco. A couple tour companies run organized tours, or you can just bring your own kayak to the launch at Nick's Cove and paddle around Hog Island and back. While I thought the experience was very cool, when I went it wasn't nearly as spectacular as the videos and pictures usually show - it was more like some light sparkles for a short moment as your paddle or hand pushes through the water, not long trails of light. It definitely wasn't something that would be easily noticeable from outside the water.

With the red tide along San Diego's shore, locals have been flocking to the coast nightly to catch a glimpse of bioluminescent waves.
The waves are created when phytoplankton, called "dinoflagellates," crash in the tide, reacting and causing bioluminescence when jostled
