The Sardine Run occurs between May and July along the East coast of South Africa when millions of sardines move up northwards. The sheer numbers create a feeding frenzy along the coastline in what is one of the largest marine events in the world. This has been dubbed "the greatest shoal on earth" by the Kwazulu-Natal tourist board.
The sardines spawn in the cool waters of the Agulhas Bank through spring and early summer. Most of the fish stay in the cooler waters of the Atlantic Ocean and end up along the west coast of Africa.
It is thought that the run containing millions of individual sardines occurs when a current of cold water heads north from the Agulhas Bank up to Mozambique where it then leaves the coast line and goes further East out into the Indian Ocean.
