Monterey Bay Whale Watch
List of Most Recent Marine Mammal Sightings
in the Monterey Bay Region
Since October 1, 2025
compiled by Monterey Bay Whale Watch
This list, updated every few days, includes reported sightings from Monterey Bay Whale Watch trips. Unusual sightings of other marine animals such as Leatherback Sea Turtles and Basking Sharks are also listed, in addition to unusual seabirds such as Albatross and Brown Boobies. California Sea Lions are mentioned only if numbers or behavior are of interest. Harbor Seals and Southern Sea Otters, which are seen on most if not all whale watching trips, are not included in the list. Each month the sightings from the previous month are moved to a monthly summary list.
