Cape of Good Hope, rocky promontory at the southern end of Cape Peninsula, Western Cape Province, South Africa.
 
It was first sighted by the Portuguese navigator Bartolomeu Dias in 1488 on his return voyage to Portugal after ascertaining the southern limits of the African continent. One historical account says that Dias named it Cape of Storms and that John II of Portugal renamed it Cape of Good Hope (because its discovery was a good omen that India could be reached by sea from Europe); other sources attribute its present name to Dias himself. 
 
Known for the stormy weather and rough seas encountered there, the cape is situated at the convergence of the warm Mozambique-Agulhas current from the Indian Ocean and the cool Benguela current from Antarctic waters.
