The best time to visit New London is during the warmer months, specifically from late spring through early autumn, typically May to October, for comfortable weather and full access to outdoor activities.During these months, the weather is generally pleasant, with average temperatures ranging from the 60s to high 70s Fahrenheit. This period is ideal for enjoying the city's coastal attractions, such as the beaches, boat tours, and outdoor dining. The longer daylight hours also allow for extended sightseeing.Couples looking for a romantic getaway will find May, June, and September particularly appealing. The crowds are typically smaller than in the peak summer months, and the weather is still very agreeable for exploring the historic downtown, enjoying waterfront strolls, or visiting nearby vineyards without the intense summer heat.Families traveling with children will find July and August to be the most suitable. While these months are the busiest, they offer the warmest water for swimming at Ocean Beach Park and a full schedule of family-friendly events and festivals.
