FAQs about the Natural History of the Inside Passage

20. What types of whales and dolphins can you see and how do you view them responsibly?

Whales begin their northbound migration to Alaska in February with most cows and calves migrating between April and May. Cruisers who visit Southeast Alaska between June and early September are most likely to see Humpback Whales, Minke Whales, Orcas (Killer Whales), Pacific White-Sided Dolphins, Dall's Porpoises and Harbour Porpoises. Whales will begin their southbound trek in late October and continue through December.

The Marine Mammal Protection Act prohibits harassment of all marine mammal species in U.S. waters. Harassment means any act of pursuit, torment, or annoyance which has the potential to injure a marine mammal, or has the potential to disturb a marine mammal by causing disruption of behavioral patterns, including migration, breathing, nursing, breeding, and feeding. Boaters must remain 100 yards from marine mammals and should keep clear of the whales’ path. Limit observation times to 30 minutes. Whales should not be encircled, trapped between vessels, or trapped between a vessel and the shore. You may not place your vessel in the path of on-coming whales causing them to surface. You should reduce speed to less than 7 knots when within 400 yards of a whale. If approached by a whale, put your engine in neutral and allow the whale to pass.

To safely observe porpoises and dolphins, observe all guidelines for watching whales. Do not steer through groups of porpoises or dolphins to encourage them to bow ride. Should a porpoise or dolphin choose to ride your bow wave, reduce speed gradually and avoid sudden course changes.
