The Grand Canyon is a year-round destination. When most people think of Arizona they think of the warm, dry desert. However, being at nearly 7,000 feet elevation means there are four seasons at the canyon. Here’s what you can expect during each season.
At 7,000 feet (2,134 meters), summer temperatures on the South Rim are relatively pleasant 50°-80°F (10°-20°C). The North Rim is 8,000 feet (2,438 meters) above sea level, so its summer temperatures are cooler, and can range from 40°-70°F (5°-21°C). Thunderstorms frequently occur during July, August, and early September, and inner canyon temperatures are extreme. Daytime highs at the river—5,000 feet (1,500 meters) below the rim—often exceed 105°F (40°C).
Winter conditions on the South Rim can be extreme. Be prepared for snow, icy roads and trails, and possible road closures. Roads on the South Rim are plowed when needed, and canyon views may be temporarily obscured by fog during passing storms. The North Rim can get heavy snowfall during the winter months. The road into the North Rim (Highway 67) is closed from the first heavy snow in November or early December to mid-May. (Please note: Entrance fees are not refundable because of weather conditions.)
Spring & Fall
Spring and fall weather in the Grand Canyon is unpredictable. Be prepared for sudden changes in the weather at those times of year. May and October can be some of the driest months, although snowstorms may occur, while late April and May can be windy. Spring and fall sport mild temperatures with warm days and cooler nights, and can be the best times to be hiking in the canyon.
