Temperatures and weather conditions often vary greatly between the canyon rim and the canyon floor; it gets progressively hotter as you descend into the canyon. Average summer temperatures range from highs of 60° to 100°F (15°-38°C), with summer lows dropping to 30° to 50°F (-1° to 10°C). In winter, highs range from 20° to 40°F (-6° to 4°C), with lows from -10° to 20°F (-23° to -6°C). Brief afternoon thunderstorms are fairly common in the summer. The South Rim Road usually remains open to the visitor center through the winter, but snow often closes the North Rim Road between December and March.

Avoiding the Crowds

Although overcrowding has not been much of a problem, with fewer than 200,000 people visiting in most years, the park can be busy, especially in summer, with more than half the park visitors arriving between Memorial Day and Labor Day. December through February is the quietest time. Those seeking solitude should visit before Memorial Day or after Labor Day. Although winter can be beautiful, park access is limited.
