The best time to go to East Haddam is during the late spring, summer, and early autumn months, from May to October, when the weather is warm and most attractions are fully open.For those looking to experience the region's natural beauty and outdoor activities, July and August are ideal. The Connecticut River is great for boating, kayaking, and fishing, and the surrounding state parks, such as Devil's Hopyard State Park, are excellent for hiking. This period is also when the Goodspeed Opera House has its main season, offering a full schedule of performances.If you prefer slightly cooler weather and fewer crowds, late May to June or September to October are wonderful. The spring brings blooming flowers and lush greenery, while autumn showcases spectacular fall foliage, particularly along the scenic drives like Route 82.
