Summer

Summer temperatures on the South Rim, at 7000 feet (2134m) are relatively pleasant 50s-80sF (10-20C). North Rim summer temperatures are cooler than those on the South Rim due to increased elevation and can range from 40s-70sF (5-21C). The North Rim is 8000 feet (2438 m) above sea level. Thunderstorms frequently occur during July, August, and early September. Inner canyon temperatures are extreme. Daytime highs at the river, 5000 feet (1500m) below the rim, often exceed 105F (40C).

Winter

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. Canyon views may be temporarily obscured by fog during passing storms. Entrance fees are not refundable because of weather conditions. 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.

Spring & Fall

Spring and fall weather 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. Late April and May can be windy. Spring and fall can be the best times to be hiking in the canyon. The road from Jacob Lake to the North Rim (Highway 67) opens mid-May and closes late fall, depending on snowfall.
