A September girls’ trip to Nantucket! September on Nantucket is classic shoulder-season weather: expect daytime temperatures generally in the mid-60s to low 70s, with cooler mornings and evenings, coastal wind, and a chance of rain. The style here leans classic coastal and polished casual - easy layers, comfortable shoes, and pieces that feel appropriate for everything from biking and sightseeing to lunch and dinner. The outfit formulas cover downtown exploring, biking and lighthouse stops, sightseeing and lunch, casual dinners, and one nicer night out — without packing a separate outfit for every occasion. Your Nantucket packing list: 4 tops — tee, Breton stripe, printed button-down + lightweight sweater 2 bottoms — jeans + navy trousers 1 midi dress 3 layers — cardigan, quilted jacket + rain shell 2 shoes — sneakers + flats Accessories — scarf, cap, belt, bags + simple jewelry The key to packing for Nantucket in September? Bring pieces you can layer as the weather changes and rewear across more than one outfit formula. Not headed to Nantucket? This same coastal fall capsule would work beautifully for Martha’s Vineyard, Cape Cod, Newport, coastal Maine, or a New England coastal weekend — just adjust your layers to the forecast.
