How to catch the bioluminescent waves in San Diego

Electric blue waves are back on the San Diego coast — for at least a couple of weeks.

What's happening: The glowing, crashing waves are visible at night during red tides, formed by a bloom of millions of bioluminescent plankton that release a flash of light when they're disturbed.

Where to see it: Beachgoers have reported seeing the bright, luminous waters at La Jolla Shores, Encinitas, Del Mar, Point Loma, Sunset Cliffs, Oceanside, Tamarack, Carlsbad and Blacks beaches.

• Be smart: The recent waning crescent moon reduces the amount of reflected light that hits the ocean at night, making the glow more visible, according to the Union-Tribune.
