Baja Year-Round Wildlife 

Before we go into month by month wildlife seasonality, know that Baja is home to abundant wildlife year-round with endless animal experiences no matter what season you visit. Baja is known as the Galapagos of the North, after all, and Jacques Cousteau famously dubbed the Sea of Cortez ‘the world’s aquarium’- for good reason!

At any time of year you can see super pods of common and bottlenose dolphins plus orca, fin, and pilot whales. California sea lions are famously playful and abundant in these waters, as are sea turtles, sun stars, sea urchins and more than 900 colorful fish species. A productive ocean with hundreds of miles of coastline also makes for a birders’ paradise, home to numerous endemic and resident birds like cormorant, pelicans, frigatebirds, boobies and many more.

Baja Whale Watching Season

When can you see whales in Baja? Whale watching is a year-round activity in Baja with 9 different whale species to look for. But many travelers target Baja’s main migratory whale season; when every year over 97% of the earth’s gray whales, plus thousands of humpback and blue whales, make the long migration to Baja.

Migratory whales begin to arrive in December and remain through April. The winter months of January through March are the best time to see gray whales in the mating and breeding lagoons along the Pacific coast. The winter months of January through March are also the best time to see migratory humpback whales at peak numbers in the Sea of Cortez.

Whale Shark Season in Baja

The official La Paz whale shark season is from October through April each year. No swimming or tours activities are permitted within the whale shark zone outside of these dates. There are whale sharks in Baja California year round, but in the late fall through late spring a higher concentration of whale sharks can be found feeding in the rich waters of the Sea of Cortez, most reliably in the Bay of La Paz.

As winter progresses, the water temperature drops, bringing large amounts of plankton. This abundant food supply makes for slightly lower visibility, but it also attracts the largest numbers of whale sharks.

These gentle giants are an endangered species and luckily, protected under Mexican law. The government strictly regulates swimming tours in La Paz to ensure the safety and ethical treatment. Due to these regulations, whale shark swimming tours in La Paz are subject to closures when regulation numbers are not met.

Sea of Cortez Mobula Ray Season

There are two Baja seasons for mobula rays. The first is during the ray’s breeding season between late April and July. Then, there’s the winter reverse migration that takes place between late November and early January, but is far less impressive.

The main event is the breeding season migration, when mobula rays are easy to spot due to their unusual acrobatic behavior—leaping from the water and back down for a loud belly flop on the sea’s surface. During this time, you can witness massive schools with thousands of mobulas swimming synchronously through the water. Snorkeling and diving are a popular activity as mobulas are harmless and not dangerous to humans.

So, When is the Best Time to Visit Baja California?

Considering the information above, we’d say you can’t go wrong visiting during the cruise season from December through May, where good weather and wildlife viewing opportunities align. Because of the comfortable weather, it’s also a great time to include a Baja California multi-day tour before or after your cruise. If gray whale watching is on your bucket list, then target the height of their calving season, mid-January through mid-March.
