  description: Massawa represents the absolute frontier of Red Sea surfing—an ancient port city in Eritrea where winter monsoon winds occasionally generate short-period swells along the African coast. The waves are small and inconsistent, but the setting is extraordinary: Italian colonial architecture, coral reefs, and the sense of surfing somewhere completely off the radar. Access is challenging due to Eritrea's isolation, but for adventurous travelers who find themselves in this historic port, the Red Sea occasionally provides unexpected waves.
