Gray Whales

Gray whales are one of the most fascinating marine mammals, known for their long migrations and unique feeding techniques. If you’re hoping to spot one, learn more about their habits, or simply marvel at their size, this guide covers everything you need to know about these gentle giants.

Where to See Gray Whales in BC

Gray whales are a common sight along the coasts of Vancouver and Victoria, making these locations two of the best places to view them.

• Victoria: During their migration periods, gray whales often travel through the waters near Victoria, BC. Whale-watching tours departing from Victoria regularly report sightings, especially in the Strait of Juan de Fuca.
• Vancouver: The waters around Vancouver also provide an excellent vantage point to see gray whales, particularly near the Gulf Islands and Howe Sound.

Both locations boast numerous whale-watching tour operators with experienced guides who can help you spot and learn about gray whales in their natural habitat. Ucluelet, Tofino, and other areas in BC are also great places to spot gray whales.

Best Times to See Gray Whales

Gray whales are most visible during their migration seasons, which are among the longest of any mammal:

• Spring Migration (February to May): Gray whales travel from the warm waters of Baja California to the nutrient-rich waters of Alaska. During this time, they pass along the coast of British Columbia, offering prime viewing opportunities.
• Fall Migration (October to December): The whales make their way back to Baja California to breed and give birth, once again travelling close to Vancouver Island’s coastline.

Peak sighting times are usually in March through November, as gray whales head past Vancouver Island.

How Big Is a Gray Whale?

Gray whales are impressive in size! Adults measure between 40 and 50 feet (12 to 15 meters) long and can weigh up to 40 tons. This makes them about the size of a school bus!

Their bodies are typically mottled gray, and covered with barnacles and other small crustaceans, giving them a unique, rugged appearance. Despite their size, gray whales are graceful swimmers, capable of covering vast distances during their migrations.

What Do Gray Whales Eat?

Gray whales are bottom feeders, a rare feeding behaviour among whales. They consume a variety of small organisms found in the sediment on the ocean floor. Their diet includes:

• Amphipods: Small crustaceans that are a staple for gray whales.
• Marine Worms: Found buried in the mud or sand.
• Larvae and Small Invertebrates: Filtered from the water or scooped up while feeding along the seafloor.

To feed, gray whales dive to the ocean floor, scoop up mouthfuls of mud and sediment, and use their baleen plates to filter out their prey. This method provides sustenance and plays an essential role in the ocean’s ecosystem by stirring up nutrients for other marine life.
