The annual migration of the sardines from the Agulhas Bank of the Cape, past the Wild Coast and up to the southern portions of KwaZulu Natal to spawn and then return, takes place during South Africa’s winter months and is a natural phenomenon known as the “Sardine Run”.


It is rated to be the marine equivalent of the famous Wildebeest migration that takes place on the Masai Mara and Serengeti plains of central Africa and is just as thrilling and spectacular to witness.


The time forgotten coastal town of Port St John’s, situated on the magical Pondoland Wild Coast has become one of the most popular destinations from which to experience the Sardine Run in all its glory.

The Pondoland coast offers not only a naturally beautiful stretch of rugged coastline, but it is also steeped in cultural traditions allowing the Amapondo people to live by and protect their cultural values.

Driven by forces not yet completely understood, millions upon millions of sardines leave their cool Cape habitat and move east following the cold current, which is in turn driven up from the south by winter storms, normally during the June to August months.


Port St John’s to Mbotyi, with the continental shelf running close to land, is a prominent location as deep water is close to shore, huge shoals travel up the coastline feeding in nutrient rich waters with concentrating both the cold current and the sardines, pushing them closer to shore and condensing the shoals, which in turn attracts a huge variety of major predators.



Sardines prefer a water temperature ranging between 14˚C – 20˚C therefore travel according to temperature changes and thermoclines.


Literally thousands of sharks, dolphins, game fish and oceanic birds follow the sardines up the coast, constantly harassing and splintering pockets from the main shoals and feeding on these at their own leisure.


As a spectator of the Sardine Run, one will often hear the term ‘Bait ball’. Thousands of common dolphins form super pods of sometimes 100 – 30 000 strong and set off in search of the sardines.


The Common dolphin has developed a technique of isolating a shoal of Sardines and herding them by using streams of bubbles, sonar and incredible teamwork into tight pockets known as “bait balls”.


They also have the amazing ability to time giving birth to their young just before the Sardine Run, thus allowing the adults to wean and teach hunting tactics to their calves during this incredibly food rich period of the year. It is truly graceful poetry to observe these incredible animals at work and at play.


In turn, many shark species take advantage of this great feed, occasionally including the Great white shark, Tiger shark, Bull shark (locally known as Zambezi), but most commonly seen are Copper/Bronze whaler sharks and Dusky sharks, which when attracted to the activity, arrive sometimes in their thousands.

At times dolphin and shark can be seen seemingly working together in containing the “bait ball” taking turns in dashing through the food source with mouths open gulping down as many sardines as possible until not a single one is left. Most “bait balls” are generally driven to the surface effectively blocking off one avenue of escape.

This, in turn, allows oceanic bird species to take full advantage of this incredible food source.


Albatrosses, Terns, Cape Cormorants and Skua’s to name a few, though the most common of these is the Cape Gannet. This is one of the truly remarkable predators from the world of birds.


These birds have amazing eyesight and have the ability to plummet 30 – 40 meters from the air into the frenzy and amazingly reach depths of 8 – 10m where they animatedly swim around snapping and swallowing any sardine within reach.


They are true plunge divers and often upon surfacing comically fight and squabble over any sardine that has been visibly brought to the surface, offering some fantastic photographic opportunities.


Bryde's whales are also regularly seen taking part in the feed by sounding and rocketing up from the depths with their mouths open to engulf as much of a “bait ball” as possible.


They can be seen on the outskirts or in the middle of the action and do not wait for any permission to start feeding, taking notice of nothing else in doing so.



A number of other whale species also make an appearance during the “run” as well, including Southern Right and Minke whales to name some.

As the migration reaches KwaZulu-Natal predatory tactics tend to change with shallow waters as the continental shelf once more heads out to sea, going out a considerable distance.


Here, predators herd sardine pockets into strategic bays, which successfully compacts the fish and blocks off a number of escape avenues, showing an amazing level of intelligence and teamwork between species.

Another totally unrelated migration that takes place during the same period as the sardine movement is that of the Humpback whales traveling from Antarctic waters northwards to the warmer waters of Mozambique and Tanzania for calving and breeding purposes.


With the narrowing of the continental shelf along the Wild Coast, family pods have the opportunity to meet up with others of their kind.


Spectacular breaches, tail lobbing, fin slapping and playful frolicking can be seen on most days throughout the winter periods of June to October months including their return.

The fascination for diving in the famous Sardine Run is shared by many avid photographers, divers and snorkellers, most come back religiously year after year to participate in the excitement and adventure. 

Boat based viewing is also very popular among photographers and general nature lovers and allows one to get closer to the action and excitement.

This phenomenon is a truly incredible and exciting experience, whether you are capturing the action on camera or memory from above or below the water and this is a MUST DO for all nature & ocean lovers. 

The Sardine Run is an ocean related experience. Bearing in mind that the ocean realm is susceptible to weather conditions on a day to day basis, and that we are dealing with nature. This allows for bad weather scenarios and variable degrees of marine activity.

Day out diving

We meet as early as possible to have enough time for breakfast and after checking all equipment, the boat will head out from the Umzimvubu River, and this is where everything starts.  After a typical and highly exciting African surf launch, we will start looking for all types of action, from Whales, Dolphins and Ocean Birds to the little silver sardine type action. Our skippers will be in touch with our “eye in the sky” gyrocopter pilot for an update on sightings.

Once action is located, our experienced crew will determine whether this action is fast moving, necessitating snorkel viewing, or more static, whereby we can go straight onto scuba equipment for those wishing to use scuba gear. 

Daily outings last for approximately 6 – 8 hours depending on sea conditions and the amount of activity about. With the action being fast and furious in conjunction with variable sea conditions, long boat rides and the whole day out at sea, outings can prove strenuous, therefore it is recommended that clients be relatively fit.

We are usually the last boats in each day, giving our clients a full day out at sea, capitalizing on whatever Nature has to offer.
