What the National Park Service says about the weather
Since Grand Canyon has elevations that range from 2,500 feet at the bottom to 8,400 feet on the North Rim, weather can vary significantly depending on the season and the specific location within the park. Winters tend to be cold and snowy, and summers have periods of excessive heat. High temperatures inside the canyon tend to be 20 to 30 degrees warmer then on the canyon's rims. Weather conditions can change rapidly, so it's wise to check forecasts before visiting.
