This is our complete San Diego whale watching guide with tips for each season and month. San Diego is one of the best locations on the West Coast of the U.S. for whale watching, as 70 miles of coastline in this area is directly in their migration path. Migrating whales can be found off shore year-round and, depending on the season, different types of whales are more prominent than others. Get up close and personal with these incredible creatures with a cruise that specializes in whale watching and knows where to go for the best chances of connecting with the whales. As frequent whale watching passengers and after conducting dozens of interviews with local experts, we are able to tell you everything about the San Diego whale watching season:

 
Whale Watching Season | Overview


The image takes you to San Diego whale watching and other tours

Whale watching season in San Diego usually runs from mid-December to late April. During that time up to 20,000 gray whales migrate through California waters. It is also possible to spot Humpback whales, fin whales, and minke whales.

However, the season doesn’t end in April. During the summer months, between May and August, blue whale sightings are possible as well as humpback whales and other species

The best time for whale watching in San Diego is in the morning. The sea is usually calmer compared to other times of the day. Also, perfect sea and weather conditions make it easier to spot whales from a greater distance. The season doesn’t matter that much, as whales can be spotted here at any time of the year.

Disclaimer: Although San Diego is one of the best areas for whale watching activities, we and the tour operators cannot guarantee stunning whale sightings at certain times. Wildlife on our planet is not 100% predictable. However, tour operators usually offer a free voucher for another tour in the seldom case no sightings happened. 

Whale Watching Tours | Winter - Spring
 


While almost every whale watching tour operator is great for spotting gray whales, we prefer the Hornblower Tours and the Flagship Tours (check the image/banner above) for three reasons:

  1. They both have excellent boats
  2. They both have extremely experienced captains
  3. The staff from both operators is extremely professional, knowledgeable and very friendly

Reserve your spot here via banner above or with the following links (both offered via GetYourGuide with excellent customer service):

Hornblower: San Diego Whale  Watching Cruise |  December - April [delayed] 
Flagship: San Diego Whale Watching Tours | December - April

Important: Hornblower delayed their season start this year (2020/21). Thus, they cannot be booked in 2020. Please book the excellent Flagship Tours instead. 

Pre-booking is highly recommended(!), as tours sell out quickly and you run the risk of not getting a spot. As a safety measure boats currently have limited passenger capacity. That makes it even more important to book well in advance!

 

Whale Watching Tours | Summer - Fall

The best whale watching tour in summer and fall you can experience is by jumping on-board of the world-famous schooner 'The America'. It's an amazing experience! Don't be afraid of getting seasick: Their boat is quite big and stable, which results in a smooth ride. While they also operate in the winter, we highly recommend to use either Flagship or Hornblower in the cooler months (see above). Book well in advance: 'The America' - San Diego Whale Watching Cruise | May - November

Winter and Spring Whale Watching


A gray whale in San Diego waters

  • Season/Months: Mid-December until late April
  • Whales: Gray Whale
  • Recent Sighting Record: It’s not uncommon that you may see a pair of gray whales. It gets even better: Recently in a January, the passengers on one tour spotted 20(!) gray whales. That’s absolutely breathtaking!

Every winter and into spring, the magnificent gray whale (up to 20,000 of them!) migrates south from Alaska down to Baja, California. That’s about 10,000 miles. The gray whale is huge – about the width of a basketball court (50 feet) and weighing up to 40 tons. To see them in the wild is truly a treat. Their goal is to reach the warmer waters so that the females can give birth to their calves. Then, when their offspring are strong enough, they head back north to Alaska around April.

San Diego whale watching in January is when things just start to heat up in the whale-watching world. A telltale sign that the Grey Whale is close by is the spout of water you will see off in the distance. The curious ones will come right up to the boat, and your heart wells with excitement to see such a humongous and mysterious creature so close in the flesh. Other Baleen whales and Toothed whales are also common sightings. And let’s not forget the harbor seals, green sea turtles and many species of birds that may choose to say “Hi!” to you along the way.

Further, in the winter season, the whale watching in March is when things start to slow down for gray whale sightings as they start their journey back up north. But that’s not to say that things cannot be any less exciting! You just never know when you will come across one or an entire pod of them. You might even see moms with their calves in April.

 

Summer and Fall Whale Watching


A nearby blue whale. Stunning!

  • Season/Months: May until August
  • Whales: Blue Whale [Fin Whale: Peak Season, Bryde’s Whale (rare) in July/August/September]

“Look! That blue whale just surfaced right beside us, so close to the boat! WOW!!” That’s what I said to my teammate when we went on a tour in August three years ago. It was so stunning!

Each summer the blue whale migration brings hundreds of blue whales near the coast of San Diego. You can spot blue whales usually from May until August. Sometimes they can even be seen as early as April or later in September when the blue whale season ends. Theoretically, you may also spot them at any other time of the year near San Diego, but that’s not very likely.

The blue whale is even larger than the gray whale. In fact, it’s the largest animal on earth and even larger than a dinosaur! San Diego sees the largest group of 2,000 to 3,000 blue whales feeding off the coast during the summer months. They can get as long as 100 feet and spout columns of water up to 30 feet. So, you can imagine that this is a great way to spot one, even from miles away! These guys will migrate from Antarctica to California. That means pods of blue whales pass by the coast of San Diego as they travel further north. Blue whales are usually found further out to sea, whereas the gray whale tends to keep closer into the shores of California.

 

Year-Round Whale Watching | + Dolphins


A humpback whale near San Diego

  • Whales: Humpback Whale, Fin Whale, Minke Whale
  • Dolphins: Common Dolphins, Bottlenose Dolphins, Pacific White-Sided Dolphins, Risso's Dolphins
  • Recent Sighting Record: Usually it’s possible to come across one, two or even three Humpbacks on a single tour. However, a recent record for humpback whales was 7 on a tour in December 2017. Once we saw a humpback breaching at least 10 times throughout the tour!
  • Recent Dolphin Sighting Record: Often you see dozens of dolphins. However, once there was megapod of about 1000 dolphins spotted on one tour!

Surfacing juvenile humpback whales are common during every season. They might even hang out in the same area of water for weeks. One of the glorious things to witness is a pod of dolphins feeding right alongside a whale or two. Humpbacks tend to move around the water a bit more than others, sometimes even zig-zagging close to your boat. Their spouting and particularly their breaching behavior are truly spectacular. Regardless if they are up close near the boat or in the distance. While you can spot humpbacks throughout the year, there is often a peak in March and April for them.

Minke whales are smaller and are able to swim underneath the boat as they are checking out the tourists (that is, if they are so inclined!) They have white sides and “Minke Mittens” which are white on its flippers.

Fin whales can be seen in San Diego waters especially in the summer months. They’re incredible it is the second-largest species on our planet after the blue whale! Its color is black or dark brownish-grey. However, the underside is white.

More ocean life: On a tour, you can experience even more fascinating ocean life such as White-sided Dolphins, Bottlenose Dolphins, and the Common Dolphin. They are usually sighted on a boat tour every season. The only dolphins that are not all-year-round are the white-sided variety, which typically show up in the winter months. They migrate down here from the Pacific Northwest waters. Dolphins are very playful and eager to interact with the tour boats. Risso’s dolphins can also be found, although they are rarer in these waters. You may also witness sea lions, several species of sharks and many different sea birds. The Mola Mola fish, a species of ocean sunfish, is also spotted in summer off the shores of San Diego.

 

Rare Sightings | Orca (Killer Whale), False Killer Whale, Pilot Whale, etc.

On a San Diego whale watching tour you could even see some rare species. Some of them are spotted less than 6 times a year and some every other year only.

Where and Tips

San Diego
United States
Is Whale Watching in San Diego Worth It?

The great thing about going on a whale-watching tour is that the tour operators all communicate with each other about whale sightings, so that as many people as possible get the chance for awesome sightings! Going on a tour, there is plenty of time to watch them glide effortlessly through the water, interact with each other, and search for food. And of course, those playful dolphins are always around to entertain and delight! It’s really intriguing when you see humpback whales surrounded by hundreds of dolphins.

The interesting thing about the whales is that you never know what their behaviors are going to be when they encounter a tour boat, and some of them can definitely show off their skills with some gorgeous tail-flukes, spouting and even swimming upside down! And blue whale calves can sometimes be spotted swimming with their mothers in the spring.

The tour guides really know these whales and their migratory habits, and are happy to share them with you during the tour. You will learn so much about these majestic mammals and gain a great appreciation for the marine ecosystem here. Every day is a unique opportunity to find and interact with any one of hundreds of majestic sea creatures.
