Two Epic Underwater Adventures...
When it comes to unforgettable diving experiences, two unique events stand out: diving with orcas in Norway and participating in the Sardine Run off the coast of South Africa. Both offer incredible opportunities to witness marine life in its most dynamic and raw form, but they are vastly different in terms of environment, marine life, and overall experience. Let’s dive into what makes each of these underwater adventures special and how they differ.
1. Animals You Might Encounter
In terms of sheer diversity of wildlife, the Sardine Run offers significantly more to see and experience, while the orcas in Norway is something truly unique on its own. Both places offer something very special…
Orca expedition in Norway
Typically taking place in the winter months (November to January) around the Norwegian coast, it offers a chance to encounter a selection of marine wildlife in the Arctic waters. During such an expedition, you might see:
Orcas (Killer Whales) – The main attraction! These apex predators are often seen hunting herring in large pods
Humpback Whales – These massive, graceful whales are often spotted in the same areas as orcas, feeding on the same herring schools.
Fin Whales – Less common, but occasionally seen.
Seabirds and Eagles – The White-tailed Sea Eagle is commonly seen in Norway, soaring above the waters or perched on the cliffs.
- Other Animals – Far less likely to see, but also spotted on occasion are animals like Sperm Whales, Harbour Porpoises and Minke Whales.
These wildlife encounters, particularly the orcas, are part of a mesmerizing Arctic ecosystem.
The Sardine Run
During the Sardine Run in South Africa, which typically takes place between May and July, there are a vast variety of incredible marine animals that can be spotted due to the huge schools of sardines being pursued by predators. Some of the animals you might see include:
Dolphins – Both Common Dolphins and Bottlenose Dolphins are known to participate in the hunt, often forming large groups to corral the sardines.
Sharks – Species like the Bronze Whaler and Dusky sharks are frequently seen hunting sardines. On occasion we also see Ragged Tooth sharks, hammerheads and other shark species
Seals – Cape Fur Seals are highly active during the Sardine Run, often swimming in packs to feed on the sardines.
Whales – Bryde’s Whales are often spotted, feeding on the sardines by lunging through the schools in a feeding frenzy. Humpback Whales also migrate past the area this time of year and are spotted very often
- Orcas – orcas sometimes show up to hunt the dolphins during the run.
Birds – Seabirds, especially the Cape Gannet, are abundant during the Sardine Run. They dive from great heights to catch sardines.
Penguins – African Penguins can be seen swimming and hunting in the waters as they dive for sardines.
Game Fish– Yellowfin Tuna and other species of tuna can be seen feeding on sardines as they are attracted to the massive bait ball.
The Sardine Run is a spectacular natural event that brings together a rich diversity of marine wildlife, making it a prime location for ocean enthusiasts and wildlife photographers!

2. Location and Conditions
Diving with Orcas in Norway
Norway offers one of the most extraordinary opportunities for divers to interact with orcas, especially around the beautiful, icy waters of the North Norwegian coastline. These majestic creatures gather here during the winter months to feast on the abundant herring. The underwater landscape is defined by cold, crystal-clear water, creating a breathtaking setting. Expect low temperatures (water often around 6°C/43°F) and the chance to experience a true Arctic dive. The visibility in these cold waters is usually excellent, allowing for long, clear views of the orcas as they circle around.
As the environment is much colder, thicker wetsuits and insulated gloves are required. The dive itself is quite calm in comparison to the Sardine Run, and the main thrill is observing the orcas from a safe distance as they move majestically through the water, sometimes even approaching divers out of curiosity.

The Sardine Run
In stark contrast, the Sardine Run takes place in the warmer waters of the Eastern Cape of South Africa, typically during the winter months (May to July). The Sardine Run involves a massive migration of sardines that attracts a frenzy of predators, including sharks, dolphins, and even whales. The waters are much warmer, usually between 18°C to 21°C (64°F to 70°F), so divers can enjoy the experience in 5mm wetsuits, which offers a bit more mobility compared to the bulky gear required for cold-water dives.
Visibility can be variable, depending on the movement of the sardines and the predators, but it’s occasionally more challenging compared to the pristine clarity of Norwegian waters. Divers can expect to be in the middle of a feeding frenzy, with schools of sardines darting around as predators hunt them down.

2. The Wildlife Experience
Diving with Orcas
Orcas, or killer whales, are apex predators and are known for their intelligence, grace, and beauty. When diving/swimming with them in Norway, the focus is primarily on observing their behavior in a relatively calm and serene environment. Orcas typically move slowly and deliberately, often working in coordinated groups to hunt. As divers, you’ll have the privilege of watching these incredible creatures from a respectful distance, witnessing their strength and elegance as they patrol the underwater landscape.
One of the most captivating aspects of this dive is the opportunity to observe the social dynamics of orca pods. The winter months in Norway bring pods of orcas close to the surface, making it an ideal time for divers to witness hunting strategies and family interactions. Orcas are known for their advanced hunting techniques and cooperative behavior, making this an unforgettable experience for marine wildlife enthusiasts.

The Sardine Run
The Sardine Run is a completely different kind of experience. Here, you’re diving into an energetic, high-paced feeding spectacle where the action is nonstop. The focus is on the sardines themselves—massive schools of them that form what looks like a shimmering cloud underwater, moving together in unison to evade predators. This is a dive for adrenaline junkies, as you’ll be surrounded by a wide range of predators—dolphins, sharks, and even seabirds—all vying for a piece of the action.
Unlike the calm and serene encounter with orcas, the Sardine Run is a chaotic and high-energy experience. Divers find themselves in the middle of a natural event that is often intense and unpredictable. The presence of large predators can make the experience feel more thrilling (or even a little intimidating), but it’s a true testament to the raw power of nature.
3. Interaction with Predators
Diving with Orcas
Orcas are not known to pose a direct threat to humans, but as apex predators, they are highly skilled and assertive hunters. In Norway, you’ll sometimes observe the orcas as they hunt, but they generally keep their distance from divers. They’re naturally curious animals, and it’s possible they might approach you, but they are not aggressive. The dive is all about respectfully observing their behavior in the wild, often accompanied by other marine species like humpback whales.
The presence of orcas in such a remote and pristine setting adds a layer of awe and reverence to the experience. Divers are encouraged to stay still and quiet, allowing the orcas to decide how close they want to get. This respectful approach ensures a safe, tranquil interaction with these magnificent creatures.

The Sardine Run
On the other hand, the Sardine Run involves more active engagement with predatory species. Dolphins will often work together to corral the sardines into tight schools, and sharks might move in quickly to hunt. While divers are typically safe, the intense action and proximity to these predators can be overwhelming for some. The experience is unpredictable, with the predators in the water often moving fast and aggressively.
For those who thrive on adrenaline, the Sardine Run is a once-in-a-lifetime opportunity to witness the power of nature up close. Divers might even find themselves swimming in close proximity to these animals during the hunt, but the event is short-lived and can quickly change direction depending on the movements of the predators and the sardines.

4. Type of Diving Experience
Diving with Orcas
The dive with orcas is generally calmer, more relaxed, and centered around observation. It offers an opportunity to connect with the majesty of these intelligent creatures in a peaceful, awe-inspiring environment. The focus is on the orca’s behavior, their social structures, and their hunting strategies. It’s a more introspective dive, giving you time to appreciate the beauty of the underwater world in the company of one of its most revered animals.

The Sardine Run
As can be seen in the videos above, the Sardine Run, in comparison, is a high-energy, fast-paced dive that requires quick reactions and an adventurous spirit. It’s more about immersing yourself in the frenzy of nature, with constant movement and unpredictable encounters. It’s a dive that’s all about the thrill and intensity of the moment, offering a completely different kind of excitement. That being said, between the chaotic moments we do still have very relaxed and playful sessions with dolphins and whales as well as seen below.
Conclusion
While both experiences offer the chance to dive into the world of marine predators, diving with orcas in Norway and participating in the Sardine Run are vastly different in terms of environment, the type of wildlife encountered, and the intensity of the dive. The orca dive is a serene, awe-inspiring experience that connects divers to the majesty of the Arctic’s apex predators, while the Sardine Run is a fast-paced, adrenaline-fueled event filled with the chaotic beauty of nature in action.
No matter which one you choose, both are life-changing experiences, offering the chance to witness some of the ocean’s most incredible species in their natural habitats. If you’re looking for tranquility and grace, diving with orcas might be the perfect adventure. But if you crave a rush of adrenaline and the energy of the hunt, the Sardine Run awaits!
