Late May through June, or September through mid-October. Shoulder seasons offer warm weather (70s-80s F), fewer crowds than July-August peak, and major events: the Montauk Music Festival (May), Hampton Classic (late August), Hamptons Film Festival (October), and North Fork wine harvest (September-October). Fall brings crisp air, foliage, and vineyard harvest events without summer congestion
