Monterey Bay has a spectacular diversity and abundance of whales and dolphins along other marine mamals and seabirds. Depending on the season, Gray Whales, Humpback Whales, Blue Whales, Pacific White-Sided Dolphins, Risso's Dolphins, Northern Right Whale Dolphins, Common Dolphins, Killer Whales, and Dall's Porpoise are frequently observed.
In late spring, summer and fall (April to mid-December) for Humpback Whales, Blue Whales and Dolphins. Winter and early spring (mid-December to March) for Gray Whales and Dolphins. Always keep a close eye on weather as Whale Watching Trips can always be cancelled due to rough seas.
