Although the park is relatively near the coast, high mountains and icefields act as barriers to the ocean's moderating influence. The result is that with the exception of the coastal Yakutat area, Wrangell St. Elias has an interior continental climate (long, extremely cold winters, and short, warm, relatively dry summers). Remember that in any season, the weather can change quickly, so it is wise to pack with clothing that can be layered, ready to peel off or add as conditions dictate.
