The sardine run of southern Africa occurs from May through July when billions of sardines spawn in the cool waters of the Agulhas Bank and move northward, past Durban along the east coast of South Africa.

Their sheer numbers create a feeding frenzy along the coastline. 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 coastline and goes further east into the Indian Ocean.

It is believed that the water temperature has to drop below 21 °C in order for the migration to take place. The shoals are often more than 7 km long, 1.5 km wide and 30 metres deep. Hopefully we get to see them this year.
