Suspended in the Atlantic Ocean between Europe and North America, the Azores is an enchanting collection of nine volcanic islands administered by Portugal. Each is blessed with an abundance of natural attractions, from the sparkling crater lakes of Sao Miguel to the dramatic cliffs of Flores and the iconic peak of Pico.
Underwater, the Azores provides divers with an equally mesmerising realm to explore, where the nutrient-rich waters of the Gulf Stream support a thriving and diverse marine ecosystem. From swim-throughs and caves carved by ancient lava flows to World War II shipwrecks, the Azores offers diving experiences that are second to none.
The archipelago’s strategic location in the Atlantic also makes it a prime destination for whale watching, with resident sperm whales joined by migratory blue, fin and humpback whales on their annual migration. Its reputation as an up-and-coming shark diving hotspot is also well-deserved, offering the chance to encounter elusive blue and mako sharks, as well as manta rays and the occasional whale shark.
With two UNESCO World Heritage sites and three UNESCO Biosphere Reserves dotting the islands, the Azores have rightfully earned their place as one of the world's most ecologically significant destinations. This is supported by an impressive choice of eco-friendly hotels, resorts and guesthouses that are prioritising environmental conservation and sustainable tourism.
In this article, we’ll highlight all of the best places to dive in the Azores, focusing on each of the island groups. To help you plan a sustainable scuba vacation in the archipelago, we’ll also share our top picks for eco-friendly accommodation in the Azores, all of which are within easy reach of dive operators.

Best places to dive in the Azores
The Azores is an archipelago of nine major islands and an islet cluster, divided into three distinct geographic groups.
To the far west lies the isolated duo of Flores and Corvo, the two most remote islands in the chain. Flores, the larger of the two, is known for its emerald landscapes dotted with countless lakes and lagoons, while the tiny island of Corvo is the smallest and most sparsely populated, with a unique volcanic crater.
Situated in the central region are the five islands of Graciosa, Terceira, São Jorge, Pico and Faial, each with their own distinct character. Graciosa features rolling pastoral hills while Terceira is known for its historic towns and São Jorge is ringed by dramatic sea cliffs. A towering volcanic peak dominates Pico Island and Faial is home to the vibrant port city of Horta.
Finally, to the east lie the two largest Azorean islands, São Miguel and Santa Maria, as well as the tiny Formigas islet cluster, a protected nature reserve inhabited by seabirds. São Miguel, the archipelago's most populous island, is famed for its emerald green calderas, steaming fumaroles and pristine crater lakes while Santa Maria offers a more arid, sun-drenched landscape.

São Miguel
The largest of the Azores islands, São Miguel, is the entry point for most visitors to the Azores and offers a wealth of natural and cultural attractions to explore. It's home to the photogenic twin crater lakes of Sete Cidades and the atmospheric city of Ponta Delgada with its centuries-old forts and churches.
The underwater landscapes around São Miguel have been sculpted over millennia by intense geothermal forces, giving rise to cavernous grottos, tubular lava formations and plunging canyons. Most of the dive sites are clustered along the island's south coast, with the town of Vila Franca do Campo serving as a gateway. The Lourenços and Sabrina Reefs are particularly prized for their potential to attract schools of mobula rays when the ocean currents are just right.
If you're based in Ponta Delgada, you can dive with Best Spot Azores, Season Challenge or Azores Diving. Dive centres in Vila Franca do Campo include Espirito Azul and Azores Sub.

Best places to dive in the Azores Islands
Best time to dive in the Azores
For the calmest and warmest water conditions, the best time to dive in the Azores is between June and September. During these peak summer months, the ocean temperatures in the Azores typically reach a maximum of 23°C (73°F). However, as summer transitions into autumn, the water temperatures begin to drop, with September often ushering in some of the best visibility of the year.
The whale watching season extends from April to October, with blue and fin whales most commonly spotted early in the season. Humpback whales, on the other hand, are more abundant in the waters around Azores in October.
The air temperatures in the Azores also vary significantly throughout the year, mirroring the fluctuations of the surrounding ocean. In the winter months, the air can be quite chilly, with temperatures dipping down to around 14°C (57°F). In contrast, during the height of summer, the thermometer can climb as high as 25°C (77°F).
Visibility in the Azores ranges from as little as 5 metres (15 feet) up to 40 metres (120 feet), largely due to the region's numerous upwellings and thermoclines. However, the offshore dive sites, which plunge to depths exceeding 2,000 metres (7,000 feet), consistently offer excellent visibility of around 35 metres (105 feet).
FAQs about diving in the Azores
Is the Azores good for scuba diving?
The Azores is arguably one of the best places to dive in Europe, with its thriving marine ecosystem nourished by the nutrient-rich waters of the Gulf Stream. Scuba enthusiasts can explore everything from swim-throughs and caves formed by ancient lava flows to fascinating World War II shipwrecks.
Additionally, the archipelago's prime location in the Atlantic makes it an excellent spot for whale watching. Here, you can see resident sperm whales alongside migratory blue, fin and humpback whales. The Azores has also established a reputation as a shark diving destination, providing opportunities to encounter blue and mako sharks, along with manta rays and whale sharks.
When to go diving in the Azores?
The best time for scuba diving in the Azores archipelago is from June to September, when the waters are at their calmest and warmest. During these summer months, ocean temperatures can peak at around 23°C (73°F). As summer gives way to autumn, the water starts to cool down, and September often brings some of the clearest visibility of the entire year.
When is whale watching season in the Azores?
The whale watching season in the Azores extends from April through October, though the specific species you're likely to encounter can vary depending on the time of year. In the spring, from April through June, the Azores serve as a migratory corridor for several species of baleen whales, including blue whales, fin whales and sei whales.
As summer arrives, the Azores becomes a hub of activity for a variety of migratory dolphin species, such as the Atlantic spotted dolphin, the striped dolphin and the pilot whale. This is also the best time of year to catch a glimpse of sperm whales, which are more abundant in the Azores' waters during the summer months.
As autumn sets in, whale watchers are treated to the arrival of humpback whales, which can be reliably spotted in the Azores in October.
Are there whale sharks in the Azores?
Whale sharks arrive in the Azores during peak plankton blooms and are most reliably spotted from July to October. While they can be seen during coastal dives (most commonly around Pico and Santa Maria), you have a better chance of sighting them at offshore sites in pursuit of bait fish.
Do you need a wetsuit for diving in the Azores?
If you’re scuba diving in the Azores in late summer (August and September), you may be comfortable in a 5mm wetsuit. Otherwise, most dive operators suggest you wear a 7mm wetsuit or a semi-dry suit to ensure you have enough thermal protection underwater.

We are a team of passionate divers and surfers with decades of combined experience in the water and travelling to all corners of the globe. After years of chasing waves and descending into the deep blue, we've created this resource highlighting sustainably run surf camps, eco-friendly dive resorts and conservation-focused ocean trips to help inspire your next adventure.
Eco Ocean Escapes was born out of a love of the ocean, an obsession with travel and a concern about the impacts of our adventures on the environments we explore. Despite the benefits that surf and dive tourism can bring to local communities, we recognised that ocean-based adventures are not always managed in a sustainable manner.
Through our articles, we hope to inspire those seeking a responsible surf or dive trip that is all about supporting local communities, preserving our coastal environments and the incredible marine species that inhabit our oceans.
