Understanding the Gray Whale Migration

What is the Gray Whale Migration?

The gray whale migration is one of the longest mammal migrations in the world. Gray whales travel approximately 10,000 to 12,000 miles round trip each year from the cold, nutrient-rich waters of the Arctic to the warm, sheltered lagoons of Baja California Sur, Mexico. This migration is primarily driven by the whales’ need to breed and give birth in a safe environment.

Why Baja California Sur?

Baja California Sur offers the perfect conditions for gray whales to mate and give birth. The region’s shallow lagoons provide a safe haven from predators like orcas and are ideal for newborn calves to grow and strengthen before making the long journey back to the Arctic. The most popular lagoons for whale watching include Laguna Ojo de Liebre (Scammon’s Lagoon), Laguna San Ignacio, and Bahia Magdalena.

Best Time to Visit for Gray Whale Watching

Peak Season: January to March

The peak season for gray whale watching in Baja California Sur is from January to March. During this period, the lagoons are teeming with whales, making it the best time to witness their spectacular behaviors up close. Here’s a month-by-month breakdown of what to expect:


In January, the first gray whales begin to arrive in the lagoons. This month marks the start of the whale watching season, and while the numbers may be lower compared to later months, visitors can still enjoy early sightings of these majestic creatures. This is also a great time to see male whales competing for mates and engaging in courtship behaviors.


February is the height of the gray whale migration season. The lagoons are filled with whales, including many mothers with their newborn calves. This month offers the best opportunities for close encounters, as the whales are more relaxed and curious about the boats. Visitors can witness calves learning to swim and breach, a truly heartwarming sight.


March is another excellent month for gray whale watching. The whale activity remains high, and visitors can continue to enjoy numerous sightings. This is also when the calves are more active and playful, providing ample opportunities for photographers and wildlife enthusiasts.

Shoulder Seasons: December and April

While January to March is the peak season, visiting during the shoulder seasons of December and April can also be rewarding.


In December, the first few whales begin their journey towards Baja. Although the numbers are not as high as in January or February, early visitors can still experience the excitement of the season’s start. Additionally, the weather is usually pleasant, making it a great time for outdoor activities.


By April, most gray whales start their journey back to the Arctic. However, some whales, especially mothers with late-born calves, can still be seen in the lagoons. This month offers a quieter, more serene whale watching experience with fewer tourists.

Where to Watch Gray Whales in Baja California Sur

Laguna Ojo de Liebre (Scammon's Lagoon)

Located near the town of Guerrero Negro, Laguna Ojo de Liebre is one of the best places to watch gray whales. This expansive lagoon offers excellent whale watching tours, allowing visitors to get close to the whales in their natural habitat. The area is also known for its stunning landscapes and diverse birdlife.

Laguna San Ignacio

Laguna San Ignacio is another prime location for gray whale watching. This remote lagoon is part of the El Vizcaíno Biosphere Reserve and offers a more intimate, less crowded experience. The lagoon is known for its friendly whales, often approaching boats out of curiosity. Eco-friendly tours in this area ensure minimal impact on the environment and the whales.

Bahia Magdalena

Bahia Magdalena, located on the Pacific coast of Baja California Sur, is a series of lagoons and channels that provide excellent whale watching opportunities. The area’s unique geography makes it a favorite spot for mother whales and their calves. Visitors can enjoy boat tours that navigate through the calm waters, offering close encounters with the whales.

Tips for a Memorable Whale Watching Experience

Choose a Reputable Tour Operator

Selecting a reputable tour operator is crucial for a safe and enjoyable whale watching experience. Look for operators that prioritize sustainable practices, follow local regulations, and have knowledgeable guides. Small group tours, like the ones we offer, are often better as they provide a more personalized experience and reduce the impact on the whales.

What to Bring

  • Binoculars: While whales often come close to the boats, binoculars can help you spot them from a distance and observe their behaviors more clearly.
  • Camera: Capture the magic of your whale watching experience with a good camera. Waterproof cases are recommended for protection.
  • Warm Clothing: Even in Baja’s warm climate, it can get chilly on the water. Layered clothing and a windbreaker will keep you comfortable.
  • Sunscreen and Hat: Protect yourself from the sun with high-SPF sunscreen and a hat, as you will be spending several hours on the water.
  • Motion Sickness Medication: If you are prone to seasickness, consider taking medication beforehand to ensure you can fully enjoy the experience.

Best Times of Day

Morning and late afternoon tours are often the best times for whale watching, as the lighting is ideal for photography and the waters are generally calmer.

How to Spot and Identify Gray Whales

Gray whales are medium-sized whales, reaching up to 49 feet in length, with the females usually being larger than the males. They are grey with white patches, which mostly consist of areas where barnacles and lice have attached themselves to the whales. In fact, they carry over 400 pounds of barnacles and whale lice. Beyond their color, there are a few distinguishing characteristics that can help identify gray whales.

Blow or spot: Like other baleen whales, gray whales have two blowholes. When they breathe out, the spray (also called the ‘blow’) sometimes takes the shape of a heart.

Flukes: Gray whale flukes are rounder than the well-known humpback flukes, with a distinct heart-shape.

Distinctive Dorsum (Back): Gray whales do not have a dorsal fin. Instead, they have a low hump and a series of six to twelve knuckles or bumps.

Breaching Behavior: Though not quite as acrobatic as the humpback whale, gray whales will emerge from the water and land in a giant splash, a behavior know as breaching.
