8.15.25

9:00 am Whale Watch & Dolphin Sightings:

6 Bottlenose Dolphins
4 Risso Dolphins
2000 Common Dolphins

We had our first sighting of marine life as we left the harbor, where Bottlenose Dolphins were swimming alongside a Navy vessel entering the harbor. We traveled beyond the Nine Mile Bank, and while we did not find whales, we did find a small pod of Risso’s Dolphins. On our return trip, we encountered a large pod of Common Dolphins. They swam all around the boat and could be seen far into the distance. They stayed with the boat for quite some time and entertained guests riding the bow waves and leaping out of the water.

9:00 am Whale Watch & Dolphin Sightings:

300 Common Dolphins

We saw a harbor seal and a flying fish with a couple of random dolphins. Then we had an unusual sighting of a gray whale, which is typically only sighted in San Diego from December through April. The whale seemed to be going both north and south. Passengers were delighted to get a glimpse. Later, we saw a pod of about 300 common dolphins, which were a joy to watch. The water was so calm and clear that you could see the dolphins through the water pretty deep. And some were leaping pretty high out of the water.

9:00 am Whale Watch & Dolphin Sightings:

350 Common Dolphins
1 Minke Whale
1 Gray Whale

It was a beautiful day on the water, and guests had the opportunity to observe dolphins and whales. A large pod of Common Dolphins, including adults and babies, was spotted being very active, with the dolphins swimming and performing high jumps. A second pod was found towards the end of the cruise, where we found a Minke Whale. The Minke lived up to its reputation of being elusive, but did surface several times to guests’ delight. A rare sighting was a lone Gray Whale, which has been seen several times recently in our waters. The Gray Whale is only here during their winter migration from December to April. However, this amazing creature has managed to hang around, and we were fortunate to catch a glimpse of it.
