Seasons and runs, about 1 Jun to 30 Jul 2027

Sardine run

In winter, vast shoals of sardines move up the east coast of South Africa, followed by sharks, dolphins and seabirds.

Between about May and July, when a band of cool water runs up the east coast of South Africa, huge shoals of sardines move north from the Agulhas Bank along the Eastern Cape and KwaZulu-Natal coasts. They draw predators: common dolphins herd them into bait balls, Cape gannets dive into them from the air, and copper sharks, dusky sharks and Bryde's whales feed through them. Divers come from around the world to watch. In some years the shoals reach the beaches and are netted from the shore. The strength and timing of the run vary a lot from year to year.

Still to be written: Sardinops, Dusky shark, Copper shark.
