All sightings from San Francisco Whale Tours vessel Kitty Kat
As we headed out of the bay and into the Golden Gate Strait, we experienced rapidly diminishing visibility due to thick fog. The previous day's trip had found a whale inside San Francisco Bay, so we were on the lookout for a humpback close to shore. There was a lot of bird and harbor porpoise activity in the strait.
We headed into the fog with good sea conditions but a visibility of 100-400 yards. At one point we spotted a mola mola (ocean sunfish) floating near the water's surface.
We found one whale between buoys 2 and 4. The fog was thick, so when the humpback did a deeper dive we were unable to reacquire it right away. We did a large circle and relocated the whale in the same spot we had left it. We put the boat in neutral and it approached us to 50 yards before fluking. The humpback's dorsal fin was unusual with a big slice down the middle of it.
We were unable to reacquire the whale. We looked for it as we headed back the way we came, noting the California sea lions on the shipping lane buoys.
We ducked into Diablo Cove to take a look at the harbor seals and watch some of the planes practicing for Fleet Week before we headed back to port.
All sightings were reported to Vessel Traffic.
