Humpback Whale Calves and Bow-Riding Dolphins Offshore

Our mid-day trip aboard Sanctuary encountered a highly active young humpback whale calf near the edge of the Monterey Canyon. The calf put on an impressive display of surface behaviors, breaching, pectoral-slapping, tail-lobbing, and rolling over its mother's back, all while surrounded by a mixed school of Pacific white-sided and Risso's dolphins.

This energetic behavior from such a young calf is often a way to develop motor skills and strengthen muscles, though it also serves as a form of communication within the pod. The presence of Risso's and Pacific white-sided dolphins interacting in a mixed group is a common sight over the canyon, where deep-water currents bring abundant nutrients to the surface, attracting diverse marine life.

Earlier in the day, our morning run navigated through a thick fog under calm seas, where we observed five humpbacks, including another mother and calf pair offshore, and a few individuals feeding just outside the harbor. Over both trips, we logged twelve humpback whales, fifty California sea lions, and a pair of southern sea otters resting in the calmer nearshore waters.

With water temperatures holding steady at 57°F and light northwest winds, the bay remains highly productive. It is always a privilege to observe these maternal bonds and multi-species interactions in such a concentrated area.

Five Humpback Whales and Sea Lions in the Fog

Our morning run aboard Sanctuary required some patience in the foggy, damp conditions, but we were rewarded with a close look at five humpback whales. Navigating through the wind and chop, we located the whales as they surfaced through the swell, their powerful blows visible even against the low-hanging mist.

Alongside the whales, we observed a small group of twenty-five California sea lions. In these conditions, sea lions often travel in loose rafts, utilizing the chop to conserve energy. The humpbacks appeared to be searching for bait fish, executing shallow dives that kept them near the surface and highly visible despite the challenging weather.

The weather today was undeniably challenging, with a steady southeast wind of 5.8 knots and damp, chilly air hovering around 55 degrees. Finding these animals in the heavy mist is always a test of patience, but our passengers were determined to brave the elements, and their perseverance paid off with some excellent, sustained viewing.

Days like today remind us that the bay is a wild, unpredictable environment. Watching these resilient marine mammals go about their daily routines in rough weather is a testament to their adaptability and strength.

Three Humpback Whales and Thirteen Orcas Offshore

Our mid-day run aboard Sanctuary was highlighted by a remarkable encounter with thirteen orcas. We were already heading back toward the harbor after spending time with humpbacks when a local fisherman radioed in a report of the killer whales, allowing us to redirect and locate the pod in the light chop.

Observing thirteen orcas together is a significant event in Monterey Bay. These apex predators often travel in coordinated family groups, utilizing the deep canyon edges of the bay to hunt and navigate as they pass through the region.

Earlier in the trip, we observed three humpback whales. These baleen whales were moving steadily through the bay, displaying typical travel patterns with regular surfacing intervals before we turned our attention to the orca report.

This excursion highlights the collaborative nature of our local seafaring community. The quick communication from a working fishing vessel allowed us to document these transient marine mammals during their passage through the bay.

Ten Humpback Whales and Common Dolphins in Glassy Seas

On today's morning and mid-day runs aboard Sanctuary, we were met with glassy, mirror-like sea conditions just outside of Moss Landing. These calm waters made for excellent visibility, allowing us to locate ten humpback whales scattered throughout the area, their blows hanging still in the quiet air.

Alongside the whales, we encountered a massive, highly active school of approximately five hundred long-beaked common dolphins. These small cetaceans are known for their high-energy social structures, and today they took full advantage of our vessel's wake, bow-riding and leaping clear of the flat surface.

Across both the morning and mid-day trips, the lack of wind and swell allowed us to observe these animals without the usual ocean noise, providing a clear window into their natural breathing intervals and travel patterns. It is always a privilege to witness the Monterey Bay submarine canyon ecosystem when the surface is this still.

Humpback Whales and Hundreds of Sea Lions Near Harbor

Today's mid-day run aboard Meridian brought us into a highly concentrated feeding frenzy just a mile outside the harbor mouth. We observed approximately twenty humpback whales feeding alongside a massive raft of over 650 California sea lions. The sheer volume of vocalizations and surface activity from the sea lions, combined with the powerful blows of the humpbacks, made for an incredible sensory experience close to home.

This multi-species feeding event was centered around dense bait balls of schooling forage fish. Humpbacks utilize various feeding strategies, and today we watched them lunging through the bait balls, often in close coordination with the sea lions. California sea lions are highly social and opportunistic feeders; by working the edges of the bait ball, they help keep the fish tightly schooled, which in turn benefits the lunging whales.

Earlier in the trip, we ventured further out into the bay where we encountered a few scattered humpbacks before crossing paths with a pod of 45 long-beaked common dolphins. The dolphins quickly approached the Meridian, riding our bow wave and showcasing their characteristic high-speed agility. Conditions on the bay shifted from calm to a light chop with a northwest wind around 10 knots, typical afternoon behavior for Monterey Bay.

Observing these complex trophic interactions so close to the harbor is a stark reminder of the bay's immense productivity. Near the harbor entrance, we also noted a southern sea otter resting quietly in the kelp canopy, a peaceful contrast to the offshore feeding frenzy.

Three Orcas and Feeding Humpback Whales Near Harbor

Today aboard Sanctuary, we were treated to a memorable encounter with three orcas right here in Monterey Bay. The trio approached our vessel under calm seas and light chop, displaying a curious behavior that allowed everyone on board a clear look at these magnificent marine mammals.

As the largest members of the dolphin family, orcas are highly social and intelligent. Watching them navigate the waters near our boat offers a humbling reminder of their position as one of the ocean's most formidable predators. Their distinct black-and-white coloration was highly visible just beneath the surface as they glided alongside us.

In addition to the orcas, we spent time with five humpback whales feeding actively just outside the harbor. These baleen whales are capitalizing on the rich forage available close to shore, putting on a steady show of blows and shallow dives as they gathered nutrients.

Days like today remind us of the dynamic nature of the Monterey Bay submarine canyon, where deep-water predators and coastal feeders can be found sharing the same rich waters just miles from land.

Humpback Whales and Massive Sea Lion Rafts Near Harbor

The morning trip aboard Sanctuary found action immediately upon exiting the harbor. We encountered a massive aggregation of life, including twenty humpback whales and a raft of approximately 800 California sea lions. The animals were concentrated around several active bait balls, creating an impressive display of surface activity just a short distance from shore.

This type of multi-species feeding frenzy is a hallmark of the Monterey Bay ecosystem. As the whales feed on schools of small fish, sea lions worked the edges of the bait balls, while Brandt’s cormorants and common murres dived from the surface. This concentrated activity allows these predators to efficiently exploit the dense patches of nutrients moving through the bay.

Conditions were windy with a light chop, which can sometimes make spotting more difficult, but the sheer volume of animals made them easy to track. We left the frenzy to go find some other species off shore, but only found a few additional Humpbacks so we stopped again at the frenzy just out side of our port.

It is a reminder that some of the most profound wildlife encounters in the bay happen within sight of the jetties, provided the bait is there to support them.

A Curious Humpback Whale and Newborn Risso's Dolphins

The morning began with glassy conditions, allowing for a remarkable encounter with a thirty-five-foot humpback whale. This individual spent forty-five minutes circling the Sanctuary, surfacing so close that the mist from its blow necessitated the use of our windshield wipers. It was a rare opportunity to see the whale’s pectoral fins and ventral pleats as it looped beneath the hull, peering back at us from just below the surface.

This type of behavior, often called mugging, occurs when a whale initiates and maintains contact with a stationary vessel. While we always maintain a respectful distance, these curious individuals occasionally choose to approach us, reminding us that the curiosity in the bay goes both ways.

Further offshore, we encountered a pod of fifteen Risso’s dolphins, including several newborns. These calves are born orange and darker than the scarred, white-gray adults and were seen traveling closely with ten Pacific white-sided dolphins and a group of California sea lions. The mixed-species interaction provided a look into the complex social structures present over the Monterey Canyon.

As the NNW winds built toward twenty-five knots, we were grateful to have spent those quiet moments with such a massive, inquisitive animal before the weather moved in.

It is a grounded reminder of the bay's power that we could witness such gentleness just hours before a gale.

Breaching Humpback Whales and Common Dolphin Super-Pods

We encountered a high concentration of humpback whales today, beginning just a mile outside the harbor. The highlight was a young male near Marina who performed a series of full-body breaches, launching his school-bus-sized frame entirely out of the water. Watching a juvenile test its strength like this offers a rare perspective on the sheer power these animals possess.

Further offshore, we located a pod of approximately 150 long-beaked common dolphins that has been frequenting the bay this week. They were engaged in a multi-species feeding event, surrounded by hundreds of diving brown pelicans and common murres. This type of surface activity often indicates a dense school of forage fish, like anchovies or sardines, being pushed toward the surface by the dolphins from below.

Our morning trip also included sightings of eight Pacific white-sided dolphins and a black-footed albatross, a pelagic bird that typically spends its life far out at sea. Despite the building northwest winds and a ten-foot swell, the visibility remained excellent, allowing us to spot white water from the dolphin pod on the horizon.

Seeing these animals interact within the complex ecosystem of the Monterey Canyon is a reminder of the bay's productivity. It was a privilege to share these sights with our guests, including a visiting bachelorette party, on such a dynamic day at sea.

Feeding Humpback Whale Aggregations and Bow-Riding Common Dolphins

The morning trip aboard Sanctuary encountered a significant gathering of humpback whales south of the canyon. We observed approximately 30 individuals concentrated in a small area, focused entirely on the dense bait balls below the surface. Despite the choppy sea state, the activity was visible from a distance as the whales broke the surface to feed.

These whales were part of a multi-species feeding event. Over 250 California sea lions and various seabirds worked the same schools of forage fish, pushing the bait toward the surface. This behavior allows humpbacks to utilize less energy while lunge-feeding, as the sea lions help to consolidate the fish into tight groups.

Our departure from the harbor was marked by a sighting of a mother sea otter and her pup, while our return journey was accompanied by a pod of long-beaked common dolphins. These dolphins spent several minutes bow-riding, utilizing the pressure wave of the boat to glide through the water with minimal effort.

Observing such a high concentration of marine life in a single area illustrates the seasonal productivity of the Monterey Bay canyon system.
