The owners of these snazzy rooftop bars know that you can't plan your trip to the Big Apple around unpredictable weather reports, so they've got your covered—literally—for any curveballs the season might throw your way.
(1) Two outdoor terraces complement an indoor loft, with floor-to-ceiling windows boasting views of Downtown Manhattan and Brooklyn, One World Trade Center and the Empire State Building. Cocktails are king here, but don't write off the venue's own beer, an IPA brewed specifically for Mr. Purple by Captain Lawrence Brewing Co. from the Hudson Valley. | Mr. Purple, Hotel Indigo, 180 Orchard St., 212.237.1790
(2) Transparent, full-service communal igloos offer guests heated seating on an outdoor deck of this rofotop bar, which also has a sleek, expansive and enclosed penthouse floor below the roof. Each igloo hosts up to 12 guests on a first-come, first-served, no reservations basis, and small parties are encouraged to mingle with potential new friends within the bubbles. A lengthy cocktail menu—both hot and cold—is on offer, and complimentary red robes toast chilly customers waiting to claim igloo seating. There are no drink minimums and no entrance fees, and both floors offer startling close-up views of the neighboring Empire State Building. | 230 FIFTH Rooftop Bar, 230 Fifth Ave., 212.725.4300
(3) Scenery is second to none at this bi-level cocktail house on the 18th floor of The James New York hotel in SoHo. Inside an intimate, elegant lounge with a working fireplace, 14-foot-tall windows provide panoramic views of Midtown, FiDi, the Hudson River and bridges spanning the East River. Walk up a flight of stairs to an airy poolside space facing One World Trade Center, ideal for unpredictably warm autumn NYC nights. | Jimmy at The James, 15 Thompson St., hotel phone: 212.465.2000
