Researchers warn Cape Cod beachgoers: "Large sharks are here"

Great white shark researchers on Cape Cod are reminding visitors that warmer weather signals not just the start of the busy tourist season, but also the arrival of the region's famous predators.

July tends to be when great whites appear in earnest as the cape's waters warm, with sightings peaking from August through October, Megan Winton, a scientist with the Atlantic White Shark Conservancy, said during a news conference at the organization's offices in Chatham on Wednesday.

"Just know that large sharks are here," she said. "They're a constant presence from June to the fall."
