Weather

New England weather can change quickly and often. As Mark Twain said, “One of the brightest gems in the New England weather is the dazzling uncertainty of it.” That said, on average, early June to mid September the average daily high temperature reaches above 70°F, peaking in mid-July. “Indian summer” is a common phenomenon from late September through the end of October with unseasonably warm, dry weather in the daytime with cooler temperatures after sunset.

From December through mid-March, the average daily high temperature hovers below 45°F and South County receives about 30 inches of snowfall annually and 50 inches of rainfall annually. Based on the tourism score, the best time of year to visit South County for warm-weather activities is from mid June to mid September.
