The Hamptons Second Summer: Why September is the Best Time to Sail Sag Harbor
Ask any Hamptons local or seasoned traveler, and they will tell you a well-kept secret: September is the absolute best month of the year on the East End. Often referred to as the "Second Summer," this magical window combines the perfect warmth of August with a rare, peaceful tranquility that disappears during the peak holiday months.
If you want to experience the water at its absolute finest, booking a late-season charter with Valkyrie Sailing Charters in Sag Harbor is the ultimate way to close out the season. Step aboard our luxury catamaran, leave the crowds on land, and discover why the smart money travels to The Hamptons in September.
Peak Water Temperatures and Perfect Weather
A common misconception is that the end of August marks the end of swimming weather. In reality, the waters around Sag Harbor and Shelter Island reach their highest temperatures of the year in late August and hold onto that heat all through September.
The afternoon air remains crisp and comfortably warm, while the ocean and bay waters are ideal for swimming, paddleboarding, or just lounging on the bow trampolines of Valkyrie. Without the oppressive humidity of mid-summer, the sailing conditions are smooth, refreshing, and perfectly clear.
Beat the Crowds: The Bay is Yours
The biggest draw of a September sailing charter is the profound sense of privacy. The summer traffic clears out, leaving the local waters remarkably peaceful.
When you set sail on Valkyrie, you will experience:
  • Open Harbors: No fighting for space as we cruise past the historic shorelines.
  • Quiet Anchoring Coves: Drop anchor in secluded bays near Shelter Island with no other boats in sight.
  • Easier Logistics: Parking near the docks in Sag Harbor becomes stress-free, and getting a post-sail table at the area's top waterfront restaurants is a breeze.
Cruising Past the Quiet Mansions
As the summer rush slows down, the magnificent coastlines of Sag Harbor take on a serene, majestic quality. Cruising aboard our wide-set catamaran offers an uninterrupted, front-row view of elite super-yachts and the legendary luxury mansions dotting the cliffs. Viewing these iconic properties against a peaceful autumn-transition backdrop is an entirely different—and far more exclusive—experience than during the chaotic July and August weeks.
Who is the "Second Summer" Cruise For?
While early summer is famous for high-energy bachelorette parties, September shifts toward sophisticated, intimate gatherings. It is the prime season for:
  • Couples' Getaways: Perfect for a romantic sunset cruise with premium local wine.
  • Local Appreciation Sails: A chance for residents to finally enjoy the beauty of their own backyard.
  • Corporate Retreation: Treat your team to a high-end, mid-week strategy and relaxation session on the water.
Secure Your Second Summer Sail
Because our crew sails straight through the beautiful month of September, availability is limited as we prepare to close out our own seasonal calendar. Experience the luxury of a private catamaran with the entire bay to yourself.
