I headed to the Golden Gate Bridge at about 4pm. High tide was scheduled for 5:20 pm. For the first 30 minutes that I walked the bridge, I only saw pelicans and other seabirds. As I walked toward the center span, I spotted a bright white spot on the water. It was a Mola mola (ocean sunfish). These are rare inside San Francisco Bay, so I was surprised to see one coming in with the tide underneath the bridge!
As the tide came up farther, I spotted a harbor seal near the center span.
Eventually I started seeing a few porpoises as well.
They were moving quickly under the bridge, usually in groups of 2-3 individuals. The water is cloudy with plankton at this time of year, so it is difficult to track the porpoises once they dive under.
I saw several large ships pass underneath the bridge. I also spotted the coast guard helicopter.
