• The East Madagascar Current (EMC) retroflection is assessed. Evidence of EMC early retroflection is
demonstrated for the first time
• Retroflection regimes are associated with EMC strength and mesoscale variability
• Knowledge of the EMC retroflection state helps understand regional ecosystem variability

Agulhas Current has an impact on South African rainfall along the eastern coast
The mechanism for low‐level convergence and collocated rainfall show similarities to that for the Gulf Stream
Regional atmospheric model experiments indicate that the Agulhas Current generates convective rainfall along the coast
