The best time to visit Old Lyme is during the late spring and early autumn months, specifically from May to June and September to October, when the weather is pleasant and the crowds are smaller.During May and June, the weather is generally mild and comfortable, great for exploring the outdoors and enjoying the natural beauty of the area. The gardens are in full bloom, and activities like kayaking or leisurely walks along the Connecticut River are particularly enjoyable. This period is ideal for couples seeking a relaxed getaway with picturesque scenery.September and October offer equally appealing conditions, with crisp air and stunning autumn foliage. The summer crowds have dispersed, making it a more peaceful time to visit local art galleries and museums, such as the Florence Griswold Museum. This season is well-suited for solo travellers or couples who appreciate a quieter experience and the beauty of New England in the autumn.While July and August are popular for their warm beach weather, they also bring larger crowds and higher prices.
