Mission Bay

Another night of very strong bioluminescence at mission bay. People are reporting it’s concentrated in deeper water, about 100 feet from shore. If you go to fiesta island you can get to deeper water without having to swim out as far.

Mission Point Park

An Orca whale was spotted in the shallow water of Mission Point Park, Mission bay, San Diego. This happened in the morning. The observer stated that the orca swam around the bay for a bit then left through the channel. This is likely a tropical orca, which have been moving up to SoCal due to El Niño overheating their home range. Credit: Casey Cole on Facebook.
