Humpback Whale Breaches and Bow-Riding Dolphins Over the Canyon

The morning trip aboard Sanctuary began with exceptionally calm, glassy water, providing the perfect backdrop for a dramatic encounter. A single humpback whale breached just off our starboard side, clearing the surface with its entire body before landing with a massive splash. This individual remained active for some time, transitioning from the breach into a series of pectoral slaps and blows across our bow.

Nearby, two other humpbacks were engaged in vigorous tail throws. These forceful movements of the fluke against the water’s surface are often interpreted as a form of communication or a way to stun small schooling fish. With the water temperature holding at 56.7°F, the bay remains a productive feeding ground for these rorquals as they move through the Monterey Canyon.

As we turned back toward the harbor, we encountered a pod of approximately 150 long-beaked common dolphins. They quickly moved in to bow-ride, utilizing the pressure wave of the vessel to travel efficiently. Along the way, we also noted California sea lions, harbor seals, and a lone sea otter resting near the kelp line.

We have included some photos from today's sightings, capturing the dolphins alongside the hull.

Days like this, where the sea is still and the wildlife is so visible, remind us of the complex ecosystem thriving just a few miles from the harbor mouth.
