🩈 Cape Cod’s August Secrets: Sharks, Seals, and Sea Serpents

August on Cape Cod is a paradox—sun-drenched beaches and salt-kissed breezes above, and a world of mystery swirling just beneath the waves. While vacationers flock to the shore for lobster rolls and lighthouses, the Atlantic is busy hosting its own seasonal spectacle. Let’s dive into the secrets that stir beneath the surface.

🐟 The Real Stars of Summer: Seals and Sharks

Cape Cod’s seal population booms in late summer, especially around Monomoy Island and Chatham. These sleek swimmers lounge like sunbathers on sandbars, drawing both admiration and attention—from above and below.

August is peak season for these apex predators, who follow the seal buffet with precision. Thanks to tagging efforts by the Atlantic White Shark Conservancy, we now know just how active these visitors are. Shark sightings have become so common that beachgoers check tracking apps as often as the weather.

But fear not—shark safety protocols are strong, and most encounters are nothing more than a fin in the distance.

Still, there’s something thrilling about knowing you’re sharing the sea with legends.

 

🌊 The Lore Beneath: Sea Serpents and Saltwater Whispers

Long before GPS and GoPros, Cape Codders told tales of serpentine creatures gliding through the fog. From the 1800s onward, reports of undulating beasts off Provincetown and Nantucket stirred imaginations. Some described them as eel-like with horse heads; others swore they saw coils the size of schooners.

Are they misidentified whales? Overzealous oarfish? Or something more cryptic?

While science leans toward skepticism, the stories persist—passed down like seashells from one generation to the next. And isn’t that part of the magic? That the sea still holds secrets we haven’t quite solved.

🐚 August’s Invitation

Cape Cod in August is more than a postcard—it’s a living story. Whether you’re scanning the horizon for dorsal fins, watching seals bob like buoys, or wondering what might lurk in the deep, this month invites curiosity.

So pack your binoculars, your sunscreen, and maybe a pinch of imagination. The coast is calling—and it has stories to tell.

Shark Season on Cape Cod

🩈 Shark Season on Cape Cod: Staying Shark Smart with Sharktivity

Cape Cod’s pristine beaches and rich marine life make it a summer haven—but beneath the waves, another iconic visitor returns each year: the great white shark. This year the Great Whites have been joined by the relatives, the hammerheads. Its a real family reunion.

 As sightings increase along the Massachusetts coastline, locals and tourists alike are turning to technology and science to stay informed and safe.

🌊 A Surge in Shark Sighting

This summer, shark activity near Cape Cod has been especially lively. From Chatham to Wellfleet, confirmed sightings of great white sharks have occurred just yards from shore. On July 16, a 14-foot white shark was spotted in Cape Cod Bay. Other reports include sharks devouring striped bass near fishing boats and swimming within 50 feet of popular beaches.

These sightings aren’t random. Cape Cod’s seal population—prime prey for white sharks—has grown significantly, drawing these apex predators closer to shore. While the presence of sharks may sound alarming, it’s also a sign of a thriving marine ecosystem.

Gone “Sharkin”

“Sharkin” on Cape Cod

Flash Back to Jaws (1975) when the fictional town of Amity on Martha’s Vineyard was terrorized by a great white shark.  Chief  Brody, marine biologist Hooper and shark hunter Quint took “Sharkin” to a new level as they pulled out all the stops to catch the murderous Great White. Shades of Captain Ahab and Moby Dick. Anyway, last year Cape Cod had it’s first fatal shark attack in 82 years! Everyone was horrified and as this year arrived towns along the Cape struggled to find ways to protect vacationers when they entered the shark’s domain.

The Shark App

The Atlantic Great White Conservancy created a Shark App ( There’s an app for that) that alerts when a shark is sighted and lets you know where, which beaches are closed and for how long. My app had been blowing up and I was determined to see a white shark in its natural environment. Whale watch boats reported seeing sharks feeding on a whale carcass. Sharks were stealing fish right off the lines of guests on fishing charters. Was I around when these things were happening? Of course not. I couldn’t be that lucky. So I picked a day to take off from work to go to the Cape to look for sharks. I told everyone at work I was going “Sharkin”. Of course it hadn’t rained in a week but it did that day. 

The Atlantic Great White Conservancy

My app was strangely quiet. Either the sharks didn’t like the rain or  no one was at the beach to see them. My friend Nancy and I wound up in Chatham. We planned to go to the Fish Pier for lunch and watch the seals. On the way there we spotted the Atlantic Great White Conservancy. What a neat little museum. It was pretty crowded because no one wanted to go to the beach in the rain but even though we couldn’t turn around without bumping into someone we had fun. The last room was a virtual reality room where we donned  a headset and voila- we were swimming with sharks! And we didn’t even get wet!

 

 

Beachcomber Seal Tour

We wrapped up our Cape day by visiting the seals with Beachcomber Seal Tours. We didn’t see any sharks because the tour stayed in the inner harbor and so far the sharks haven’t ventured in. The channels and low water level seem to discourage them. But there were certainly enough seals for the sharks to have a hearty lunch if they wanted to drop by. The light misty drizzle changed to serious rain while we were on the water. The captain pulled out the disposable rain capes and pretty soon our boat looked like a convention of ghosts with the breeze flapping our ponchos. Our “Sharkin” day  didn’t yield any sharks but we had a good time anyway. 

The Day has A Seal of Approval

The Seals of Cape Cod

Nothing like spending a day with herd of gray seals in Chatham, Cape Cod. I confess I didn’t just want to see the seals. I thought there might be a small chance that I’d get a glimpse of a Great White Shark. It’s been 7 years since I’ve been back to see the seals so I figured it was about time. Of course it meant another weekend drive over one of the bridges but I was hoping I’d be going against the traffic. Turns out I was. The Sunday exodus from the Cape had route 6, the Cape Highway, backed up for miles leaving the cape.

Beachcomber Seal ToursYellow beachcomber boat

I’d called Beachcomber Seal Tours before I started for the cape. They said they had room for me on the 12 pm tour. I knew it would be close but I jumped in the car and headed off. With luck and traffic on my side I arrived with 10 minutes to spare! The folks at Beachcomber Seal Tours are very warm and welcoming. They make sure the children are fitted with life jackets and everyone gets a “pit stop” before we are all loaded onto a bus for the trip to the marina.

The little orange boat holds about 29 people. We boarded by climbing a little step stool and stepping over the side. The captain stands at a center console to pilot the boat. It makes it a little hard to hear his commentary but the fresh sea air in your face on a sunny day is a pretty awesome way to spend a summer afternoon.

Sleeping SealSeals, seals and more seals

We passed Nauset Beach, recently the scene of a Great White sighting. As we swung toward North Beach the seals were suddenly right in front of us. They looked like they were piled on top of each other but our captain explained that each one has it place. A steady moaning sound came from the piles of seals. A few were in the water. They would rise up from the bottom and then sink back down. This is how they sleep. True enough, none of them had their eyes open!

Before heading back we took a run past the shark buoy and Lighthouse Beach.

Too soon it was time to return to the dock. The very successful 90 minute tour was at an end. No great whites but lots of seals.

Mystic Aquarium Part 2

Yes, I know this has taken me awhile but here it is. How we spent the 2nd half of our trip.

Lunch was at the Penguin Cafe.

Although there were a few tables inside in the air conditioning they were all taken. Most seating was outside under the big umbrellas. Lunch was simple fast food, hot dogs, fries or onion rings, hamburgers, chicken fingers etc. I think we filled up on drinks because we were all sweating so bad.

After lunch we headed inside the Aquarium. Here the lighting was subdued. It was crowded. There was a shark/ray touch tank, a jellies display, a large variety of different tanks showcasing the various environments such as river, pond, rain forest etc. All enjoyable and all pretty much the usual fare.

The Sea Lion Show was  a bit different from the ones I’ve usually seen. It started with a seal being paraded around right in front of the audience and then the show itself seemed to concentrate more on natural behaviors than the contrived tricks you normally see. It was both educational and fun.

From there we went back outside to cross to another building where there was a special display about Frogs and the theater. We watched the Angry Birds short movie (15 minutes) in 4 D so yes, we felt the wind blow and water sprinkled over us while the action on the screen seemed to jump out at us.

After the movie we exited into the special exhibit area where a shark cage was predominantly displayed so you could take pictures. There was a reptile section with american alligators and the special frogs exhibit. Getting photos of the frogs was hard because of the crowds around each display. I tried to get a picture of the poison tree frogs , both tiny and brightly colored, but it was very difficult through the glass of their terrariums.

Following the Frog Exhibit we headed back outside, through the marsh again. The frogs and turtles were still hanging out but we didn’t linger. We were headed for the penguin display.

DSC_3298a copy

I made the mistake of going into the air conditioned lower level to see the penguins as they swam underwater. When I came back out the heat and humidity fogged the camera lens. As far as I know there is nothing to do but wait when that happens. Wiping it off doesn’t seem to work.

Sadly it was still fogged when we went past the Northern Fur Seal exhibit and Mr. Seal was posing and grooming on a rock.

DSC_3304 copy

It made it impossible to get  clear photos. I was surprised how big Mr. Fur Seal is. For some reason I always thought they were smaller animals.

One last stop at the Beluga exhibit and it was time to leave. I think everyone was tired from the heat but it was a good, relaxing day. Well worth the drive.
