Nate Rouette, On The Water’s Social Media Manager, went to the beach expecting brown sharks. After hours of dead rods and dropped baits, one last-cast pickup turned into something neither he nor his brother Nelson had ever pulled from Cape Cod sand: a juvenile tiger shark, its unmistakable vertical stripes lit up under a headlamp in the middle of the night.
The plan was simple. Nate — who runs OTW’s social channels and spends plenty of his own time on the sand and in a kayak chasing stripers — hadn’t fished in over a week, an eternity by his standards. So he texted his brother Nelson with a low-stakes idea: grab some eels and try for brown sharks that evening. Nelson was in before Nate finished typing.
“It’s a Tiger, Nels!”
What followed was a slow night typical of surfcasting for sharks: two quick pickups that came unbuttoned, then a long stretch of nothing. The brothers had all but decided to call it when one of the rods bent. The fight was short but strange — the fish stayed low, then suddenly reversed direction in the wash. When Nate’s headlamp hit the fish coming up the beach, the “little brown” they expected turned out to be something else entirely.
A Warm-Water Visitor With Company
The timing tracks with what’s been showing up in the water around the Cape lately. Just days before Nate and Nelson’s catch, a tiger shark was spotted about three miles off Mashpee’s Popponesset Bay, feeding on a leatherback turtle — the season’s first tiger shark sighting near Cape Cod. Shark researcher John Chisholm told the Boston Herald that as water temperatures continue climbing, more warm-water species are showing up in the region.
That lines up with what NOAA Fisheries has been documenting for years. Tiger sharks have historically ranged from Cape Cod to Florida and the Gulf of Mexico, favoring water temperatures of 72°F or warmer — conditions that used to keep them well south of Massachusetts most of the season. A NOAA-backed study published in Global Change Biology found that warming on the Northeast Continental Shelf has pushed tiger sharks’ seasonal range northward and pulled their arrival earlier in the year, a shift researchers tie directly to climate-driven ocean warming.

Not the First Tiger on the Cape
This isn’t the first time OTW has covered a Cape Cod tiger shark, either. In August 2024, Massachusetts angler Brendan Ryder and friends landed a juvenile tiger shark on the south side of the Cape after nearly seven hours of soaking eels for brown sharks. A year later, in August 2025, Cape Cod regular Hans Brings — no stranger to landing oddball southern species from the surf — hooked and released another juvenile tiger from the same stretch of coast. Between those catches, this summer’s turtle-eating tiger sighting off Mashpee, and now Nate and Nelson’s fish, it’s shaping up to be a pattern rather than a fluke.
None of that made the moment feel any less surreal in the wash that night. The brothers kept the shark wet, worked quickly to free the hook, snapped a few photos, and got the release on video before the young tiger kicked once and disappeared back into the dark. For two anglers who grew up fishing every corner of the Cape for stripers, blues, and albies, it was a reminder that the fishery they know is still changing — one warm-water surprise at a time.

FAQ
Are tiger sharks common on Cape Cod?
No. Tiger sharks are still considered rare in New England waters, though NOAA data shows their range has been expanding north as ocean temperatures rise, with more sightings and shore-caught juveniles reported from Cape Cod in recent summers.
Was a tiger shark recently spotted off Cape Cod?
Yes. In mid-July, a tiger shark was spotted about three miles off Mashpee’s Popponesset Bay feeding on a leatherback turtle — the season’s first confirmed tiger shark sighting near the Cape.
What water temperature do tiger sharks prefer?
Tiger sharks generally favor water temperatures of 72°F or warmer, which is why they’ve historically stayed south of New England for most of the year.
Has a tiger shark been caught on Cape Cod before?
Yes. On The Water has reported at least two other shore-caught juvenile tiger sharks on Cape Cod in recent summers — one by Brendan Ryder in August 2024 and another by Hans Brings in August 2025.
