All sightings from San Francisco Whale Tours vessel Happy Days

We started off our trip towards the Farallon Islands with beautiful weather. As we passed north of the shipping lane, we found three humpback whales feeding, and two more spouts in the distance. The group of three was split up into one pair and one solo humpback. The pair surfaced in synchrony the entire time we were there.

We continued on towards the islands, slowing at one point to look at hundreds of bright orange Pacific sea nettles drifting in the waters beneath us. 

As we approached the islands, I noticed something bright red near Sugarloaf. I started taking pictures and captured a few splashes. Birds started to swarm to the area. 

As we approached, I was able to confirm that we were approaching a large slick of blood, likely caused by a Great White shark attacking a sea lion. The frenzied birds dove into the water, some surfacing with pieces of meat. Sea lions were barking loudly and swimming in groups close to the rocks in Fisherman's Bay. We likely had missed the attack by just a few minutes. 

If you look closely where the splash is, you'll notice a fin!

We continued around the islands towards Saddle rock, noting a large number of common murres perched on the cliffs. Water visibility was excellent, and we could see the bottom in many spots. 

In Mirounga Bay near the Jordan we spotted a couple of Elephant seals and some Northern Fur seals on the rocks. There was a large group of sea lions in the water. 

Since we had such excellent weather, we decided to head out towards the continental shelf. We had been heading west for just a few minutes when we spotted 2 humpbacks breaching over and over again. 

We approached slowly and were treated to one breach about 300 yards from our boat. 

When they were done breaching, the whales started slapping their pectoral fins, sometimes rolling over as they did so. We watched three humpbacks diving and slapping for several minutes. 

We noticed some huge spouts in the distance and thought that we might have some blue whales. We headed towards them and sure enough, we spotted 3 blues. Two of them were a pair surfacing together. There was one more large spout in the distance. 

We were far from home, so we had to turn around and start our journey back towards the pier. On our way back in we noticed a few king salmon leap out of the water, as well as some moon jellies and harbor porpoises.

8am: 

We found whales on this trip northwest of shipping lane buoys 1 & 2. A pilot vessel floated nearby, waiting to guide incoming container ships. 

A pair of two adults surfaced together several times, doing fluke dives in synchrony. Occasionally they were lunge feeding in synchrony as well. 

Several other whales were feeding on their own in the area for a total of 5-7 humpbacks. Huge clouds of birds hovered over each whale. One whale did a single pectoral fin slap. 

The water was glassy with beautiful sunny weather. We also saw moon jellies, harbor porpoises, a harbor seal, and some California sea lions resting on the shipping lane buoy.

2pm: 

We returned to the same spot for our next trip. There was a lot of traffic, with six or seven container ships passing by us over the course of the trip.

The first humpbacks we saw were past the container ships, so we waited to approach. Before we began approaching a humpback surfaced closer to us.

We were in 90 feet of water and saw many shallow dives from the whale, with very few fluke dives. At one point the whale did a side lunge feed, showing its pectoral fin. Big clouds of birds hovered over the whales.

On our way back in, we picked up a plastic bag from the water. 

All sightings were reported to Vessel Traffic.
