Diving in the Azores Islands: Best Dive Sites + Eco-Friendly Hotels
Looking for the best places to dive in the Azores? Discover some of the best dive sites in the Azores and eco-friendly hotels for a sustainable scuba vacation in Portugal.
Suspended in the Atlantic Ocean between Europe and North America, the Azores is a collection of nine volcanic islands administered by Portugal.
Each is blessed with an abundance of natural attractions, from the sparkling crater lakes of São Miguel to the waterfall-drenched cliffs of Flores and the iconic peak of Pico. Honestly, we couldn’t believe some of these places were real; they were THAT beautiful!
Underwater, the Azores provide divers with equally mesmerising environments to discover, 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 offer some of Europe’s best diving experiences.
The archipelago’s strategic location in the Atlantic also makes it a prime destination for whale watching. Resident sperm whales are joined by migratory blue, fin and humpback whales.
The Azores’ reputation as an up-and-coming shark diving hotspot is also well-deserved. There’s the chance to encounter elusive blue and mako sharks, as well as manta rays and the occasional whale shark.
With three UNESCO Biosphere Reserves dotting the islands (in addition to two UNESCO World Heritage Sites), 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 Azores hotels, resorts and guesthouses that are prioritising environmental conservation and sustainable tourism.
In this article, we’ll highlight all of the best dive sites in the Azores, focusing on each of the island groups. To help you plan a sustainable scuba vacation in Portugal, we’ll also share our top picks for eco-friendly hotels 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, plus spectacular scenes of waterfalls tumbling over cliffs.
The tiny island of Corvo is the smallest and most sparsely populated, with a unique volcanic crater that is best visited on day trips.
Situated in the central region are the five islands of Graciosa, Terceira, São Jorge, Pico and Faial, each with its own distinct character.
Graciosa features rolling pastoral hills while São Jorge is ringed by dramatic sea cliffs. Meanwhile, Terceira is known for the UNESCO-listed town of Angra do Heroismo.
A towering volcanic peak dominates Pico Island and Faial is home to the colourful 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 and steaming fumaroles. Santa Maria offers a more arid, sun-drenched landscape.

São Miguel
The largest of the Azores, São Miguel, is the entry point for most visitors to the islands and offers a wealth of natural and cultural attractions to explore.
It’s home to the photogenic crater lakes of Sete Cidades and Europe’s oldest tea plantation, as well as 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. This has given 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.

Due to the relative isolation of Flores and Corvo, the marine life here has been allowed to thrive. As a result, the islands are home to some of the best dive sites in the Azores, making it well worth the adventure.
Corvo was the first island in the Azores to set up a voluntary marine reserve around Caneiro dos Meros (renowned for its dusky groupers). Meanwhile, Flores’ rugged coastline boasts everything from sheltered bays to large caves and caverns.

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. September often ushers 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 the 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). This is 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
Are the Azores good for scuba diving?
The Azores Islands are arguably one of the best places to dive in Europe. The archipelago’s thriving marine ecosystem is 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. There are fantastic 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. 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. However, 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. These include 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. These 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.
