In this article, we share everything you must know about whale watching in San Diego. 

Whale watching in San Diego

Why San Diego is perfect for whale watching

More than twenty thousand Gray Whales travel a distance of 16000 km (10000 miles) from Alaska to Baja California’s lagoons, every year. 

After giving birth to their young ones, and watch them grow stronger in the warmer Baja California waters, the whales journey north again in spring. 

This trip is the longest known distance any mammal migrates annually.

With more than 110 km (70 miles) of San Diego’s coastline directly in the migration path, San Diego is the perfect spot to watch these massive animals from a boat. 

Here is a drone video of whales having fun off the coast of San Diego.

This Gray Whale migration lasts from mid-December to April.

If you are in San Diego from mid-June to September, you may not be able to see Gray Whales, but you can come face to face with Blue Whales. 

Blue whales, the most endangered of the great whales, are found off the coast of San Diego from mid-June through September. 

The rich California coast becomes a feeding ground for up to 3000 Blue Whales during the summer months. 

Even though to catch a glimpse of these 100-feet long whales, you must venture further into the sea, they are easy to spot because of the 30-foot column of water they spout in the air. 

Regular San Diego Harbor Cruises, where you get to see the city’s skyline and numerous other attractions, are also popular with tourists.

Whale watching season in San Diego

The best time of the year to go whale watching in San Diego is from mid-December to April, which coincides with the Gray Whale migration.

With more than 20,000 Gray Whales migrating through California waters, your chances of spotting them are high. 

During this season, besides the Gray Whales, you can also spot Humpback Whales, Orcas, Fin Whales, and Minke Whales. 

Early in the season, whales swim closer to the coast, so the whale cruises only sail out a maximum of 8 kms (5 miles) into the ocean. 

When the whales are swimming back to Alaska, the yachts must sail out as far as 20 kms (12 miles) from the coast. 

A milder whale season exists from mid-June through September when you can spot Blue whales.

Best time to whale watch in San Diego

Whales are active all through the day (and night!), so anytime is a good time to go on a whale watching tour in San Diego. 

However, if you are looking for the best scenic light for taking photographs, we recommend a sunrise or sunset whale watching cruise. 

Out in the ocean, the best overhead light is from 11 am – 3 pm, which results in beautiful blue waters in your photographs.

What to expect during whale watching tour

Whale watching is an attempt to see some of the largest animals on Earth in their natural habitat, making it an exciting activity. 

However, knowing what to expect from the tour helps you make the most out of your experience. 

No guarantee

No one can predict the exact location of the whales. 

Some whale watching tour companies’ guarantee sightings’, but what they mean is that if you don’t spot a whale during one of your trips, they will give you a free ticket to return another day. 

The one thing that can be guaranteed about whale watching is that every trip out into the ocean is different. 

So, what to expect?

You have a very nice chance of seeing a whale in action during your cruise, so don’t give up hope. 

Be outdoors, keep listening to the narration and be ready to spot the below-given indicators of a whale’s presence. 

The Spout (or Blow)

Whales breathe quickly because they can take in air only when they are out on the surface.

When they breathe out, warm, moist air exhaled meets the cool air at the ocean surface and creates what we call a spout (or blow).

A gray whale’s blow can spray up to 15 feet high, and each blow is visible for about five seconds. 

All whales have a pattern – they dive for 3 to 6 minutes, then surface for 3 to 4 blows in a row, each around 30 seconds apart, and then descend again for 3 to 6 minutes. 

When you are scanning the horizon for a whale, look out for this spout. 

The Flukes (or tail)

After it has 3 to 4 blows in a row and has enough Oxygen, the whale decides to dive. 

Whale's Flukes

A gray whale often displays its around 4-meter (12 feet) broad fan-shaped flukes or tail just before diving.

The weight of the tail above the whale’s body helps gain some momentum for the deep dive. 

Knuckled Back

If the whale is close enough and there is enough light, you can spot the Gray Whale’s back during and after the blow.

Its skin is black or gray and shiny because of the water. If you watch closely, you can spot the knuckled ridge along the spine. 

Whale’s footprint

Whale's footprint

After a whale goes underwater, it leaves an elongated, smooth oval of calm water known as the footprint.

Since it is often impossible to see the whales beneath the surface, this ‘footprint’ helps people track them without seeing them. 

Breach and Splash

Once in a while, Gray Whales hurl themselves out of the water and plunge back with a tremendous splash.

The act of getting out of the water is called ‘Breaching’.

If you are lucky, other whales nearby may try to copy the first whale, and you may end up witnessing a spectacle.

Whale watching from the shore

Not all whale watching needs to be from a cruise. 

San Diego has a few great spots, such as Birch Aquarium at Scripps, Cabrillo National Monument, Torrey Pines State Reserve, etc., to view the grey whale migration from the shore. 

All the locations offer expansive views of the Pacific Ocean.

However, a cruise is the best way to see Blue Whales as they tend to stay farther out at sea.
