La Jolla, California, is renowned for its stunning coastline, but nothing quite compares to the enchanting beauty of bioluminescence that illuminates the night sea. This natural phenomenon occurs when microscopic organisms, such as phytoplankton, emit light in response to movement or stress. During certain times of the year, particularly during warm summer nights, visitors can witness the ocean glowing with a mesmerizing blue hue, creating a truly unforgettable experience. This ethereal display is not only a spectacle for the eyes but also a reminder of the wonders of nature and the delicate balance of marine ecosystems.
