Why Nantucket’s September Feels Like a Second Summer
September on Nantucket—or “second summer”—is when the island truly comes alive for the thoughtful traveler. The ocean, warmed by months of sun, keeps the air and water inviting well into fall. The island atmosphere decelerates: shop the boutiques on downtown’s cobbled lanes, enjoy fresh bites at The Lemon Press, explore historic sites like the Nantucket Whaling Museum, or simply soak in the peaceful tone of your vacation rental.
Beaches become less crowded during the off-season.
Events & Activities to Enjoy
Second Summer doesn't mean quiet — it means a different, more local kind of alive:
- Nantucket Island Fair: A barnyard, farm stand, dog show, livestock show, scarecrow building, live music, and plenty of island flavor. One of the most genuinely local events of the entire island year. Charming, family-friendly, and completely unlike anything else on the island. Come by bike if you can.
- Nantucket Restaurant Week: Seven days of special menus and unforgettable dining at some of the island’s finest restaurants, including James Beard Award–nominated chefs. Book early — even Restaurant Week fills up fast.
- Nature & Exploration: Trails and hidden coastal spots become yours to discover without the summer rush. The 35 miles of bike paths feel entirely different in September — quieter, cooler, and more beautiful. And the Milestone Cranberry Bog in the Middle Moors, managed by the Nantucket Conservation Foundation, is a stunning and unexpected visit — 170 years of cranberry farming history surrounded by rolling hills and freshwater ponds.
Travel becomes—dare we say it—pleasant: ferries and flights continue to run frequently but now with shorter lines and smoother transitions. Bonus: Rental prices dip. September is the time for affordable luxury, whether you’re eyeing a snug cottage or an oceanfront estate.
