If you want to experience a memorable whale watching tour, then we highly recommend San Diego. It’s 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.
Whale Watching Season | Overview
The whale watching season in San Diego is split into two parts: You can spot gray whales in winter and spring. Usually from mid-December until late April. Blue whale sightings are possible in the summer from May to August. Humpback whales, fin whales, and minke whales can be seen year-round.
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 so 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 stunnning 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.
Recommended Whale Watching Tour | Pre-Book
The image above takes you to our preferred tour! While almost every whale watching tour operator is great in San Dieg, we prefer the Hornblower Tours for three reasons:
- They have the largest boat which makes it less likely to get seasick
- They probably have the most experienced captain
- Their staff is extremely professional, knowledgable and very friendly
Reserve a spot here: San Diego Whale and Dolphin Watching Cruises by Hornblower (via GetYourGuide with excellent service). Important: Pre-booking is highly recommended(!), as tours sell out quickly and you run the risk of not getting a spot.

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

- 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.
The lighthouse is located on the north shore of Kauai at Kilauea Point.
The National Wildlife Refuge which is the area around the Lighthouse is open from Tuesday until Saturday from 10 a.m. to 4 p.m. Closed on Sundays and Mondays and major official holidays. If you miss the opening hours, you can get a good but more distant view of the lighthouse from the parking in front of the Wildlife Refuge gate.
To avoid the crowds come late afternoon around 3 pm. This allows enough time to walk around, observe the seabirds flying around and get a closer look at the lighthouse. Pretty busy before midday and especially on Tuesdays. Cars are queuing and the gate will be closed if the two parking areas are full.
If you like to get a view inside the lighthouse, tours are offered only on Wednesdays and Saturdays between 10:30 am and 2:30 pm every 30 minutes. If you like to take part come at 10 am and inscribe for the first tour. Places are limited. The guided tour is for free.
The humpbacks migrate to Hawaii and arrive in December, heading back late April. Best months to spot them are February and March just in front of the lighthouse.
The Laysan Albatross colony can be observed from November to July. You can use the provided monocular to see them closer. The nest in an area west to the lighthouse. The nesting birds and chicks can be seen only from the lighthouse area.
