Red tide - this happened last year too, don't wade in it.
"Red tide returns to Coastside", article from Half Moon Bay Review 9/20/10. "The waters are running red in – so say government officials who have determined a new algae bloom off the Coastside is causing the ocean to take on a reddish-orange color.
Officials with the U.S. Coast Guard and the confirmed on Monday afternoon that the odd coloration in the sea waters was being caused by algae, and not any kind of pollutant. As part of a phenomenon called “red tide”, decaying organic material from the algae can turn a large expanse of ocean water a reddish color.
Various people in recent days have spotted the reddish tinge in the sea along Surfer’s Beach. The plankton species that causes red tide is non-toxic, but experts warn that beachgoers should avoid stepping in the ocean waters because the algae bloom indicates a higher risk of toxic algae being in the water. The Coastside experienced a similar algae bloom last September."
