Diving in Portugal (Azores) in April

Conditions in April

Heading to the Azores in April for a dive trip? You're in for a treat, though it’s important to set expectations for the conditions. April marks the transition from winter to spring in the Atlantic, meaning you’ll experience a dynamic environment. The weather can be a mixed bag; expect a combination of sunny days, but also be prepared for some rain showers and cloud cover. It's truly a time where you can experience "four seasons in one day" across the islands. Winds can still be present, and while not as strong as deep winter, they can contribute to choppier surface conditions, especially in exposed areas. Flexibility in your dive planning is key, as dive operators often choose sites based on the day's prevailing weather.

Sea state in April can vary significantly. While you might encounter calm, glassy waters on sheltered coasts, open ocean crossings to offshore banks or between islands can be lively. If you're prone to seasickness, it's wise to pack suitable medication. Water temperatures are on the cooler side, ranging from 16-18°C (61-64°F). This isn’t tropical warmth, so a good quality wetsuit is essential. Visibility, however, can be absolutely stunning. The clean, open ocean currents bring crystal clear water, offering visibility frequently exceeding 20 meters (65 feet) and often pushing 30 meters (100 feet) or more on a good day.

Currents in the Azores are a defining characteristic of its diving, and April is no exception. While some shallower, sheltered bays offer calmer conditions, many of the prime dive sites, especially those offshore, are exposed to strong Atlantic currents. These currents are precisely what attract the incredible pelagic life the Azores are famous for. Drift diving is common, and you should be comfortable with it. Your dive guides will be experienced in reading the currents and planning dives accordingly, so always follow their briefings and instructions.

What you will see

April in the Azores is a fantastic time for pelagic encounters, though you're catching the start of the full "big animal" season. This is a prime time for mobula rays (often confused with manta rays, but distinct species found in the Atlantic), and while not yet in their massive summer aggregations, individual sightings or small groups are possible, particularly around offshore seamounts. You might also encounter common dolphins and bottlenose dolphins, often seen from the boat between dive sites or even passing by underwater. Pilot whales are also residents and can be spotted.

Sharks are a major draw for the Azores, and while the peak for blue sharks and mako sharks is later in the summer, April can still offer exciting encounters. You might spot less common species like the sleek shortfin mako or the occasional blue shark, especially if you venture to deeper, offshore sites. The Azores are also home to a variety of endemic fish species, and you'll see large schools of pelagic fish like barracuda and bonitos. Macro life, though not the primary focus, is present and often overlooked. Keep an eye out for colourful nudibranchs, crabs, and shrimps tucked away in the volcanic rock formations.

One of the unique aspects of April in the Azores is the chance to witness the rich biodiversity that thrives around the volcanic structures. Look for large groupers, stingrays resting on sandy patches, and various species of moray eels peeking from crevices. While the truly massive whale aggregations and super-pods of dolphins are more common later in the season, April provides a more intimate experience with the ocean's giants as they begin their migrations or settle into their feeding grounds. It’s a compelling time for divers who appreciate the raw, untamed beauty of the Atlantic.

Top dive sites this month

For April, focusing on sites that offer a mix of shelter and pelagic potential is a good strategy. The Princess Alice Bank, while always a jewel, might be more challenging to reach consistently due to weather. However, if conditions allow, this offshore seamount between Faial and Pico is legendary for mobula rays, schools of tuna, and sometimes even sharks. It's a truly world-class site, but definitely for experienced divers comfortable with deep diving and strong currents.

Closer to shore, the islands of Pico and Faial offer excellent options. The dive site known as Baixa do Norte (North Banks) off Pico is another fantastic seamount known for large schools of pelagic fish, barracudas, and the chance of encountering larger pelagics. Similarly, the Formigas Islets and Dollabarat Bank, a small archipelago and submerged seamount further east, are marine protected areas teeming with life. While a longer boat ride, they often deliver spectacular sightings of mobulas, various shark species, and monumental aggregations of fish. Divers should still be prepared for cool water and potential currents at these prime sites.

Practical tips for your trip

Given the water temperatures of 16-18°C (61-64°F), you'll want a substantial wetsuit. A 7mm full wetsuit, potentially with an integrated hood or a separate hood, is highly recommended to stay comfortable during multiple dives. Some divers even opt for a semi-dry suit for added warmth. Don't forget your gloves and boots! This time of year caters well to experienced divers who are comfortable with varying conditions, cooler water, and potentially strong currents. While there are some shallower, more sheltered sites suitable for beginners, to fully appreciate the Azores in April and access the best pelagic action, you should have at least an Advanced Open Water certification and comfort with drift diving.

When planning your liveaboard trip, keep in mind that while some liveaboards operate during April, the full high season for liveaboard options (especially those consistently travelling to offshore banks) typically ramps up from late spring into summer. However, you can still find good options for combining day trips from various islands with potential overnight trips if conditions permit. Packing should include layers for unpredictable weather – rain gear, warm fleeces, and windproof jackets are essential alongside your swimwear. Always carry seasickness medication if you’re prone to it, as crossings can be choppy. Be aware that dive operations often rely heavily on local weather forecasts, and itineraries can change at short notice for your safety and comfort. Embrace the wild beauty and be prepared for an authentic Atlantic diving adventure!
