The best time to go to Harwich is during the summer months, particularly from late June to early September, when the weather is warm and all attractions are open.
This period offers consistent sunshine and pleasant temperatures, ideal for enjoying the beaches and outdoor activities. The ocean water is warmest, making it superb for swimming, boating, and paddleboarding. You'll find all the local shops, restaurants, and cultural events in full swing.
For families, the summer is superb as it coincides with school holidays. Harwich's family-friendly beaches, like Red River Beach and Bank Street Beach, are fully staffed with lifeguards, and there are plenty of activities such as mini-golf and ice cream shops to keep everyone entertained.
Couples looking for a lively but still relaxing break would also enjoy this time. You can spend days exploring the various villages of Harwich, cycling the Cape Cod Rail Trail, or enjoying fresh seafood at waterfront restaurants. Evenings often feature live music and bustling harbour areas.
If you prefer fewer crowds and slightly cooler weather, late spring (May to early June) or early autumn (September to early October) can also be lovely, though some seasonal businesses might have reduced hours.
