 The island weather is most likely to be cloudy with a mist and the wind is often in the mid 30s to 40 mph.The Japanese current in the Pacific to the south of the island regulates the temperature and gives it the pronounced temperature lag (August and September are the warmest months and the island's record low occurred in April).Despite it being a tundra climate, it is spared the vicious cold of places like Barrow, Alaska where temperatures in winter can rival those of interior Alaska in winter.
