Make the Most of September on Long Island
September offers the perfect combination of lingering summer weather and early fall atmosphere. You can spend one weekend near the water and the next wandering through an apple orchard, pumpkin patch or historic village.
Event dates, hours, admission policies and weather-related plans may change. Before attending, verify the latest information directly with the event organizer.
Exploring Long Island’s villages is also one of the best ways to discover what makes each community feel like home.
