Before heading out for a scuba diving adventure in Santo Antão, it’s important to consider a few factors. Ensure you have your certification if you're planning on diving deeper than beginner levels. Diving tours typically last around one to two hours, so it’s best to book your trips in advance, especially during peak travel seasons. Remember that the waters around the island can be cold, so wearing a wetsuit is highly recommended. While diving is popular, be aware that the island’s diving infrastructure is still developing, so amenities might be limited compared to larger tourist hubs.

Getting to Santo Antão is relatively easy, with regular ferries running from São Vicente island, where the nearest airport (Mindelo) is located. The ferry ride takes about 30 minutes, and once on Santo Antão, you can get to the diving sites by car or with the help of local operators. Many dive centers offer transportation directly to dive locations, making it convenient for visitors staying in Ponta do Sol or other popular towns. If you’re staying in Porto Novo, a 20-minute drive will get you to nearby dive spots like the ones in Ribeira das Patas and further along the coast.

The best time to dive in Santo Antão is during the dry season, which lasts from November to May. During this period, the water is clear, calm, and relatively warm, providing excellent visibility for underwater exploration. The peak tourist season typically runs from December to April, which means you might encounter more divers. However, the waters around Santo Antão remain pleasant throughout the year. The rainy season (June to October) can bring rougher seas and lower visibility, so for optimal conditions, plan your dive trip during the dry months.

Santo Antão’s diving spots can easily be visited as part of a day trip from nearby São Vicente. A ferry ride across the turquoise waters to the island offers an exciting way to begin your diving adventure. You can join a day trip organized by local dive shops that include multiple dives at different spots, providing a comprehensive experience of the island's underwater beauty. Aside from the diving, these day trips often include a chance to explore the island's charming villages, dramatic landscapes, and unique cultural experiences, making for a well-rounded day of adventure.
