This weekend we went to Encinitas to see a rare ocean phenomena known as bioluminescence caused by a red tide.
By day, a red tide is unsightly and uninviting, with water the color of coffee. But at night, during this unusual phenomenon caused by a plankton bloom, the waves are a brilliant, almost neon blue. This wonderfully surreal scene has played out almost nightly along San Diego beaches for the last few weeks.
Here are a couple of cool pictures of what we saw. The waves were coming about every 30 seconds and we spent almost two hours watching.
