Sao Nicolau: Tarrafal Bay SN Dive Site – Cape Verde

Site Overview

Tarrafal Bay SN is a intermediate-level reef dive site located off the Sao Nicolau coastline in Cape Verde, offering an extraordinary combination of volcanic underwater landscapes and rich Atlantic marine biodiversity. The site is accessed by boat from Ribeira Brava, typically 29 to 34 minutes depending on sea conditions. Tarrafal Bay SN reaches a maximum depth of 18 meters with the most productive diving occurring between five and 15 meters where the volcanic walls and reef structures provide shelter and feeding grounds for diverse marine species. The underwater topography features dramatic volcanic formations including vertical walls, overhangs, coral-encrusted pinnacles, and sandy channels that create a mosaic of distinct ecological zones. Marine life encounters commonly include Loggerhead Turtle, Green Turtle, Parrotfish, Whitetip Reef Shark, along with numerous smaller reef species that inhabit the volcanic substrate. The water temperature ranges from 22 degrees in winter to 27 degrees in late summer, with visibility typically between 15 and 28 meters during the calmer months from May through November. Seasonal visitors including humpback whales from February to May and whale sharks from July to October add an extraordinary dimension to dives in this region. The site's position in the eastern Atlantic means it benefits from nutrient-rich upwellings that sustain prolific coral growth and attract large pelagic species year-round. Sao Nicolau is increasingly recognized as one of Cape Verde's premier diving destinations, offering uncrowded conditions and authentic Atlantic diving experiences that remain largely undiscovered by the broader diving community. The moderate currents and varied depth profile provide engaging diving for certified divers looking to expand their experience.
