LOS ANGELES – The red tide has returned, and you know what that means – bioluminescent waves are lighting up the Southern California coast in brilliant blue for the second time in 2024.

The bioluminescent algae known scientifically as Lingulodinium polydra arrived in the area earlier this week and was most recently spotted in parts of Venice Beach.

The phenomenon associated with red tide – or algae blooms – is full of dinoflagellates that react when moved by the water. During the day the water can be a deep red, brown or orange color due to pigmentation. At night the water turns what many refer to as “electric blue.”

“I remember wanting to see this phenomenon years ago and it was one of the top things on my wish list. Now I've been able to watch it every night for almost a week!” One person commented Facebook page dedicated to where you can see bioluminescence in SoCal.

According to the Scripps Institute of Oceanography, there is no public health warning related to red tide.

So far, enthusiasts have shared photos of bioluminescence from several hotspots, including Newport Beach, San Clemente, Playa del Rey and Ventura.

Although there is no exact way to know when and where the bioluminescent waves will light up, some people recommend that the best time to take a look is between 9 p.m. and 3 a.m

“What I noticed about this outbreak is that the bio doesn't come out until after 10pm – it seems like they have their own internal clock as to when to tune in,” one person commented.

“Depends on the time of the flood. The higher tide is bringing them closer to shore,” said another.

Another bioluminescence observer even shared some tips with others: Walk down to the shore, let your eyes adjust, and look for larger amounts every 30 minutes.

“It takes time for the outside sets to break. It's not because of the shorebreak. We've been here for an hour and saw three big sets that were really good. Give her some time,” was the tip. “It’s not particularly bright here, but it is there.”

The last time bioluminescence was spotted in the region was in early January to welcome the New Year.

Have fun hunting!
