Sea temperature todayAtlantic Ocean

Spanning both hemispheres from Iceland down to South Africa, the Atlantic Ocean has no single swimming season, as the warmest months depend on which side of the equator you are on. There is no single average: the warmest month ranges from an August mean of 11.7 °C at Reynisfjara (Iceland) to a September mean of 27.6 °C at Praia (Santiago).
