Porto Santo's diving is defined by a productive mix of natural reef, wall, cave, and deliberately sunk wrecks that together attract a consistently rich cast of species. The Dusky Grouper, Great Barracuda, Common Stingray, and Common Octopus are observed across virtually every site. Shallow beginners' reefs such as Maldivas sit alongside deep wall dives like Baixa do Max, giving the area real range across skill levels. Artificial structures including the Cordeca and Madeirense wreck have accelerated colonisation, while the cave system at Ilhéu de Cima adds overhead-environment interest for intermediate divers. All sites are boat access.

Water temperatures stay mild through winter before climbing to their warmest in late summer, making Porto Santo diveable year-round. The warmest and most settled conditions fall between June and October, when visibility tends to be at its most generous. Outside this window, conditions remain comfortable though a thicker wetsuit becomes worthwhile as temperatures ease back toward their winter minimum.

A good proportion of Porto Santo's sites are rated for beginners, including Maldivas, Baixa dos Leques, Baixa do Alex, and Baixa do Cotrim. These range from shallow reef dives to moderate depths, all reached by boat. Intermediate and advanced divers are also well catered for, with wall dives, caves, and deeper wrecks available once experience levels increase.
Every dive site listed in Porto Santo is boat access only, so divers will need to go out with an operator. Rhea Dive Center is the local operator serving the area. This means even the shallower beginner sites require a short boat trip, which also allows the operator to position divers precisely over reef structures located offshore.
Porto Santo's site roster covers natural reefs, reef walls, drift dives, cave systems, and artificial reefs including two deliberately sunk wrecks, the Cordeca and the Madeirense. Several sites combine more than one structure type, such as Baixinha, which features natural reef, wall formations, and an artificial reef in a single dive. This variety means divers can choose different experiences across multiple days without repeating the same environment.
