Golden-hour strolls and sweater-weather evenings—September on the Cape at its best.
I’ll just say it: September is my favorite month on Cape Cod. The humidity breaks, the parking lots empty out, and the restaurants suddenly have open tables again. The water is still warm, the days are still long, and the Cape settles into a quieter, more relaxed version of itself — what locals call “Second Summer.” For those of us who live here, it feels like a reward. For visitors, it’s one of the Cape’s best-kept secrets.
If you’ve only ever visited in July or August, September is going to surprise you. In the best possible way.
And for those who love the Cape but want to avoid the peak-season hustle entirely, September is the ultimate off-season getaway — the weather is still genuinely beautiful, prices ease up, and you’ll experience the Cape the way locals do.
Why Cape Cod in September Feels Like a Second Summer
Daytime highs often hover in the 70s — perfect for beach time, sailing, or a long walk along the Cape Cod National Seashore. Humidity eases, and nights invite you to slip on a sweater, linger by a firepit, or stargaze under crystal-clear skies. Without summer’s bustle, you’ll find open tables at restaurants, easier parking at beaches, and a more relaxed pace in your favorite towns.
Festivals & Events That Bring the Cape Alive
September may be quieter, but it’s far from sleepy. Plan your getaway around these beloved local happenings:
- Eastham Windmill Weekend — A time-honored community celebration with a parade, craft fair, and family-friendly fun on the green.
- Harwich Cranberry Arts & Music Festival — Celebrate cranberry season with artisan makers, live music, and classic Cape flavors.
- Seaside LeMans Kart Race — Held each September at Mashpee Commons, this fast-paced event features high-speed Formula One-style karts racing on a track in the heart of town. Beyond the thrills, it’s also a major fundraiser supporting Cape Cod nonprofits, making it a day with real community impact.
- Just beyond September: Wellfleet OysterFest in October is my absolute favorite fall festival on the Cape. It’s a delicious reason to return to the Cape this time of year—think shellfish, music, and small-town charm. Enjoy the Yarmouth Seaside Festival with kite-flying, a craft fair, fireworks, and a parade that bring the season to life. And come groove out to the Outer Cape Roots & Blues Festival that happens by Nauset Beach.
Second-summer weekends bring parades, fairs, and local flavor across the Cape, like the Wellfleet OysterFest.
Outdoor Adventures Without the Crowds
- Bike the Cape Cod Rail Trail for car-free cruising through marshes and woodlands, with fewer riders and gentler temps.
- Hike the trails at Wellfleet Bay Wildlife Sanctuary — bird migrations, coastal vistas, and peaceful boardwalks.
- Stroll Main Streets in Provincetown, Harwich Port and Chatham — easier parking, shorter lines, and plenty of time to browse.
- Visit iconic lighthouses — watch favorites like Nauset Light (Eastham) and Chatham Light glow in golden September light. Fun fact: Nauset Light is the iconic lighthouse featured on every bag of Cape Cod Potato Chips!
Tips for Planning Your Second Summer Getaway
- Pack layers — Days can feel like July, but evenings often dip into the 50s.
- Book early — September is popular for reunions, weddings, and long weekends. Secure your ideal place:
large homes for rent on Cape Cod or
group accommodations (stay close, with room to spread out).

- Embrace the slower pace — The joy of the shoulder season is unhurried discovery.
