San Diego's nighttime surf has taken on a spectacular glow, thanks to the return of bioluminescence to the local beaches. Enthusiasts and casual observers have been treated to a natural light show as waves crash along the coast in dazzling neon blue. Vishwas Lokesh, a hobbyist photographer, shared shots of the phenomena with NBC 7, showcasing this surreal spectacle across various San Diego County beaches, including Torrey Pines State Beach and Carlsbad State Beach.
According to Dr. Drew Lucas from Scripps Institution of Oceanography, highlighted in a statement obtained by NBC San Diego, the effect is caused by Lingulodinium polyhedra – a type of dinoflagellates that should really get credited for bringing the glow-up to the ocean's surface. Dr. Lucas likens their swimming prowess to that of an aquatic Michael Phelps. These tiny organisms only reveal their luminescent capabilities after dark when agitated by movement in the water – be that a wave, a boat, or an unsuspecting surfer slicing through the water.
Dr. Lucas told NBC San Diego that swimming in these glowing waters is "in general, just fine" for humans. The remarkable scenes have been occurring more frequently in San Diego, stirring excitement and raising questions about the conditions that trigger such an increase in these light-producing plankton.
For those looking to witness the glow, there’s a window of opportunity extending into the warmer months. These blooms, also known as red tides by day, can last anywhere from a few days to even months, as mentioned in an interview by Mark Girardeau after his bioluminescence sighting was reported to FOX 5 San Diego. He also observed that the neon waves seem to be getting more vibrant as nights go by – indicating that this may not be just a passing flash in the pan.
For those who can only venture to the shores during daylight, Dr. Lucas' fridge trick serves as a DIY viewing experience to slightly recreate the magic at home: trap some red tide water in a jar, chill it in darkness, and give it a shake to spark that bioluminescent blue hue potentially. Whether by the coastline under a moonlit sky or through a jar in the fridge, San Diego's bioluminescent waves promise a memorable spectacle – making it a must-see for locals and tourists alike.
