July is the hottest month of the year in Maine and is the peak of the tourist season. Tourists flock to attractions like the Acadia National Park, the only national park in New England where temperatures are in a pleasantly warm range of 59°F (15°C) to 79°F (26.1°C). The warmth of the temperate sun nourishes the conditions as the daily sunshine averages 9 to 10 hours across the state. Rain averages 2" (51mm) to 3" (76mm) over most parts of Maine as the humidity levels drop in July. Green mountains, freshwater lakes, swelling rivers, and mesmerizing landscapes make a great vacation in the warmth of the soothing sun rays. The beaches are not exactly enthralling as those in the other parts of America, and the ocean water temperatures rarely cross 65°F (18.3°C) even in the peak of summer. For swimming or surfing, the southeast part of Maine, such as Portland or Kennebunkport, offer warmer waters.
