Dive Azores . Whale Project Azores

Advanced Open Water certification (or equivalent) and a minimum of 30 logged dives. A mandatory check-out dive to assess skills and equipment is required before the trip. The site involves strong currents and no bottom references for much of the dive, so it is not suitable for inexperienced divers. Inexperienced scuba divers can join as snorkelers.

Courses are conducted in English, Portuguese, Spanish and French by Dive Azores instructors.

All rental gear is MARES: BCDs, regulators, 7mm one-piece neoprene wetsuits with hoods, 3mm booties and gloves, adjustable fins, and 12L and 15L steel tanks with both DIN and Yoke fittings. Dive computers, torches and SMBs are also available for rent. Air is filled with a Bauer compressor.

A 25% refund is issued if no sharks appear. The quoted success rate for blue shark sightings is above 90%, but Dive Azores acknowledges that sightings cannot be guaranteed as blue sharks are highly migratory. The best season is July to September.

Yes — Horta's hospital has a hyperbaric chamber. For offshore dives such as Princess Alice Bank, the nearest recompression facility is 2 to 2h30 away, which is why Dive Azores enforces conservative, non-decompression-limit dive profiles on those trips.

Groups are normally limited to a maximum of 5–6 divers per dive guide. The centre aims to match divers of similar experience levels within each group.

The Dolphin School is a 4-day/7-night residential program running in July, August and September, developed by Joana and Tiago based on their work with dolphins in the Azores. It includes 3 snorkelling sessions with wild dolphin pods, 1 whale watching tour, training sessions, educational lectures, snorkelling equipment, airport transfers, 7 nights in shared accommodation 15 minutes from the base, and a certificate of participation. Participants must be 18 or older, have good swimming skills and prior snorkelling experience. The price starts from 795 EUR per person.

July, August and September are the best diving months. Water temperatures reach 21–23ºC, visibility at Princess Alice Bank runs 25–30m, and this is also the peak season for blue shark encounters and mobula ray sightings at Princess Alice. Whale watching runs from March to November, with spring bringing blue, humpback and sei whales and summer peaking for sperm whales.
