To avoid overcrowding at San Diego area beaches ... you can now check out the amazing bioluminescent light show from the comfort of your home. The Scripps Institution of Oceanography has a pier cam that lights up online every night around 8.
The blue bioluminescence is a defense mechanism created by the massive red tide that's been off the coast from Baja all the way to LA.
The online version also great if you don't like the rotting stench the red tide has been giving off.
You can check out the pier cam at scripss.ucsd.edu/piercam
Here is a video of surfers riding the bioluminescent waves!
