Off the coast of Cape Cod, great white sharks are increasingly becoming a familiar presence, reshaping both the local environment and visitor experiences in this popular vacation destination. Over recent years, the region stretching from the northern tip of the Outer Cape down past Chatham has emerged as one of the world’s premier seasonal habitats for great whites, drawing observers eager to witness the apex predators in their natural setting.
This resurgence is closely tied to the growth of the gray seal population, which rebounded significantly following the implementation of the Marine Mammal Protection Act in 1972. Scientists estimate that seals in the Cape Cod area have increased from around 2,000 in 1994 to as many as 50,000 by 2017. The seal recovery has, in turn, attracted great white sharks, which use the area as a hunting ground during the summer and fall months.
The presence of great whites has prompted a range of responses on land. Residents and businesses of Cape Cod have embraced the sharks culturally and economically, with an abundance of shark-themed merchandise and ecotourism opportunities. Several companies now offer shark-spotting tours departing from towns such as Chatham, where spotter planes help locate sharks for tourists who can observe them from boats. These tours typically last two to three hours, making Cape Cod a uniquely accessible location for shark ecotourism when compared to destinations requiring multiday excursions. Cage diving operations, which involve chumming waters to attract sharks, remain illegal in Massachusetts waters but continue offshore in federal areas.
While shark-related tourism grows, so too have safety measures and public awareness. Lifeguards across the Outer Cape beach communities have adopted shark-specific equipment and protocols, including tourniquets and “Stop the Bleed” kits, supported by real-time shark tracking through detector buoys and the crowd-sourced Sharktivity app. Despite some high-profile incidents—including three shark attacks between 2012 and 2020, one of which was fatal—the local economy appears resilient. The Cape Cod Chamber of Commerce reports tourism revenue increased from nearly $2 billion in 2019 to around $2.8 billion today, even as visits to the Cape Cod National Seashore have declined.
Local attitudes reflect a mix of caution and acceptance. Longtime residents and surf shop owners note that while the sharks have altered how people approach ocean activities, they have not substantially deterred overall beach attendance. For example, demand for swimming pools has surged as some residents seek safer alternatives to ocean swimming. Still, lessons about coexistence with marine predators resonate widely among visitors and locals alike, who frequently use technology and local updates to gauge current risks.
Experts like Greg Skomal, a marine biologist with the Massachusetts Division of Marine Fisheries, emphasize that the white shark’s return is a conservation milestone. He notes that shark sightings close to shorelines have coincided with fewer people venturing far into the water, indicating behavioral adaptations in response to the animals’ presence.
For many, such as Nicole Sweeney, a longtime Cape Cod visitor, encountering a great white remains a moment of awe. On a recent shark tour, she described a close encounter with a 10- to 12-foot male shark as “incredibly awe-inspiring.” As Cape Cod continues to welcome both sharks and people, the challenge lies in balancing ecological success with safety and tourism sustainability in one of America’s iconic coastal destinations.
