Cape Cod National Seashore Climate

The Cape's weather changes significantly with the seasons. Spring can often be cool and damp with temperatures ranging in the mid-40s. Summer usually provides warm days, ranging between 70 and 80 degrees, and cool nights. Winter on Cape Cod is milder than inland, but dampness and wind chill can make winter days bitter cold. Temperatures range between 30 and 40 degrees in mid-winter, but intervals of below zero as well as milder temperatures can also occur. It is important to dress properly for the weather, reagrdless of the season. In the warmer months, visitors need to take precautions to avoid overexposure to sun, wind and biting insects. It is advisable to wear a hat as needed, as well as long sleeve and long pants when conditions warrant. In winter, it is important to dress in layers and keep one's head covered, to avoid exposure, and potentially, hypothermia.
