The best time to go to Shelter Island Heights is during the summer months, from June to September, when the weather is warm and the island is fully operational.During this period, all the island's amenities, including restaurants, shops, and recreational activities, are open and readily available. The ferry service also runs more frequently, making travel to and from the island very convenient. This time of year is superb for those looking to enjoy the beaches and outdoor activities.For those who prefer a quieter experience with pleasant weather, late spring (May) and early autumn (October) are also excellent choices. The crowds are smaller, but the weather is still generally mild enough to enjoy walking, cycling, and the island's natural beauty.
