Grand Canyon itself influences weather. Tremendous changes in elevation cause large differences in temperature and precipitation. The coolest, wettest weather station in the region (North Rim - 8,297 feet/2,529 m) is less than eight miles from the hottest, and one of the driest stations (Phantom Ranch - 2,460 feet/750 m). The coldest temperature recorded was –22 °F on the North Rim on February 1, 1985. The warmest was 120°F at Phantom Ranch on several dates during summer months.
