All sightings from San Francisco Whale Tours vessel Kitty Kat
Our first trip of the day was very foggy. As we got close to the Golden Gate Bridge, we had a huge amount of bird activity from a wide variety of species. Many of them were flying west.
We felt that we were passing a whale, but we continued out into the Golden Gate Strait. We found one humpback by Mile Rock. We approached very slowly, our already slow pace further reduced by a strong western swell/wind and the incoming tide.
The whale was feeding right on the tide line, along with huge groups of birds. We saw a few fluke dives, one of them around 100 yards away from us.
After we left the whale and headed back in, we found a whale by the north tower of the Golden Gate Bridge - the one we had missed on the way out.
When we headed back out for our second trip, the whale had moved further into the bay with the tide. We found it in between Alcatraz and the Golden Gate Bridge. It was moving west. We stayed 200-300 yards away as we followed the whale out, watching fluke dives and lots of bird activity over the whale.
The whale would occasionally do a lunge feed followed by some time spent on its side, slapping or waving its pectoral fin.
Anchovies boiled at the surface of the water. Birds were attacking each other in attempts to steal food.
The whale stopped just outside the north tower of the Golden Gate Bridge near Diablo Cove . We also stopped and put the boat in neutral.
After a few dives, the whale moved in towards us, surfacing 100 yards away.
It disappeared for a while, then reappeared 20 feet from our bow. It surfaced again on our stern, where it did a few fluke dives. We saw some more lunge feeding and pectoral fin slapping.
We saw quite a few harbor seals outside the bridge.
The whale slowly moved away from us towards the center span of the bridge. We made sure it was at least 100 yards away before we started moving.
By the time we headed out on our third trip of the day it was almost low tide. The outgoing tide made the Golden Gate Strait a lot rougher than it had been in the morning.
We headed up the south side of the strait when we spotted a spout by Point Bonita. We waited for a container ship to pass before we approached.
The humpback was feeding in the same spot as the whale on the 3pm trip yesterday. We put the boat in neutral and had our stern to the swell, allowing us to float 200 yards from the whale.
The whale worked the same area the whole trip, moving in circles around us and coming as close as 100 yards. We only saw two fluke dives from this whale, indicating that the anchovies were most likely close to the surface.
Near the end of the trip, the whale swam to our stern and came up on the other side. We made sure it was 100 yards away before we moved. The whale continued to parallel us at 120 yards for a few minutes. Once we were half a mile away we came up to speed.
All sightings were reported to Vessel Traffic.
