Already this summer, more than 100 sharks have been spotted off Cape Cod, including 33 in the past week alone.
On at least five occasions in the past week, beaches on the Cape have been closed to swimming temporarily due to shark sightings near shore.
Researchers tagged four sharks off Wellfleet and Truro on Tuesday, bringing their total so far this season to 12. That's the most they've ever tagged this early in the season.
"It's been a banner year," said Greg Skomal, a shark biologist at the Massachusetts Division of Marine Fisheries.
But where exactly are most of these sharks being seen?
NBC10 Boston took a closer look at the sightings recorded on the Atlantic White Shark Conservancy's Sharktivity app and broke them down by town so you can see where most of them are being spotted before you head to the beach.
- Chatham/Monomoy Island: 33
- Cape Cod Bay: 26
- Orleans: 23
- Truro: 21
- Provincetown: 16
- Wellfleet: 3

Researchers on Cape Cod launched a new study last month focused on the hunting and feeding habits of the region's great white sharks following last year's two attacks on humans, including the state's first fatal one in more than 80 years. They hope the work contributes critical information to the ongoing debate over how to keep Cape beachgoers safe.
One Massachusetts citizens group is calling for eliminating federal protections on seals, which have been blamed for drawing an increased number of great white sharks to the region in recent years.
