The waters off Pico Island host twenty-four resident and migratory cetacean species, the highest concentration in the North Atlantic.
Sperm whales patrol the submarine canyon system that drops to three thousand metres less than five kilometres from shore, while bottlenose dolphins, Risso's dolphins, and Atlantic spotted dolphins frequent the shallower coastal shelf. Blue whales, fin whales, and sei whales pass through on seasonal migrations between Arctic feeding grounds and tropical breeding areas. This density of marine life drew American whaling fleets to the Azores in the eighteenth century, and Pico became the archipelago's whaling capital until the practice ended in 1987.
Madalena, the island's main port, sits on Pico's western coast facing Faial across a narrow channel. The marina serves as the primary departure point for whale watching operators, many of whom employ former whalers as spotters and guides. These vigia lookouts, positioned on clifftop stations around the island, communicate sightings to vessels via radio, directing boats to active feeding areas or surfacing pods. The tradition transforms colonial-era hunting infrastructure into conservation tools. Operators follow strict approach protocols established by the Azores regional government: vessels maintain fifty-metre distances from cetaceans, limit engine noise near resting pods, and restrict encounter duration to thirty minutes per group.
Pico whale watching madalena expeditions run year-round, with peak sighting windows from April through October when water temperatures rise and migratory species arrive. Sperm whales remain present in all months, diving for giant squid in the canyon depths and surfacing to breathe in predictable intervals. Morning departures between eight and noon benefit from calmer seas and better light for photography. Zodiac rigid inflatables seat eight to twelve passengers and reach sighting zones within twenty minutes, while larger motorboats accommodate thirty guests with enclosed cabins and bathrooms. Marine biologists accompany research-focused tours, collecting photo-identification data and hydrophone recordings that contribute to long-term population studies. The Instituto do Mar maintains a regional cetacean database tracking individual animals across decades, and visitors' photographs often provide critical migration and behavior documentation.
