The best time to visit Block Island is during the summer months, from June to September. During this period, the weather is warm and ideal for beach activities, with temperatures ranging from 21°C to 27°C (70°F to 80°F). The island comes alive with events, open shops, and bustling beaches. Summer offers the most pleasant conditions for outdoor adventures like hiking, biking, and sailing, making it a perfect time for families and couples to visit. However, summer also brings the highest number of visitors, so book accommodations early.
If you prefer a quieter experience, visit during the shoulder seasons of May or October. These months offer cooler temperatures (15°C to 21°C, 60°F to 70°F) but still allow for beach strolls and sightseeing without the summer crowds. Fall, in particular, offers stunning foliage and a more peaceful island experience.
Winter (November to April) is the off-season, with many businesses closed and fewer ferry services. However, if you enjoy solitude and brisk seaside walks, winter provides a serene escape. The island is quiet, making it ideal for those seeking a retreat from the hustle and bustle of everyday life.
