The climate of Iceland's coast is subpolar oceanic. The warm North Atlantic Current ensures generally higher annual temperatures than in most places of similar latitude in the world. Regions in the world with similar climates include the Aleutian Islands, the Alaska Peninsula, and Tierra del Fuego, although these regions are closer to the equator. Despite its proximity to the Arctic, the island's coasts remain ice-free through the winter. Ice incursions are rare, the last having occurred on the north coast in 1969.[54]
