Grand Canyon Weather & Climate

Elevation and season typically dictates average temperatures at the Grand Canyon. Elevations at the top of the South Rim average about 7,000 feet with the North Rim averaging 8,000 feet. As you descend into the Canyon, the elevation drops gradually to about 1,500 to 2,000 feet on the Canyon floor. The higher the elevation, the cooler the temperature. With such a wide range of elevations, the Grand Canyon experiences a variety of weather conditions. Summer thunderstorms and winter snowfall adds to the weather variety. See the Weather and Temperature Charts below.

Summer Weather & Temperatures.

At the top of the Rims, the summer high temperatures are typically quite pleasant. If you plan on hiking into the Canyon and riding a mule into the Canyon, keep in mind that temperatures can climb rapidly as you descend and you must dress accordingly and be sure you carry an adequate supply of drinking water.

Summer thunderstorms frequently occur during July, August, and early September with the potential for torrential rains, frequent lightning, and sudden flash floods. These thunderstorms are extremely variable in intensity and location and occur mainly between the hours of 11 AM and 6 PM. Some of these storms can reach severe levels, with large hail and damaging winds.

Fall Weather & Temperatures.

Summer heat give way to cooler temperatures during the fall months of September and October with progressively cooler temperatures in the latter fall periods. The summer rains typically diminish in mid September with a drier fall period the norm with fewer days of precipitation. However, late summer thunderstorms or early winter snow storms have been known to take place during the transition season, making for sudden changes to the weather.

Winter Weather & Temperatures.

Winter weather conditions on the South Rim can be harsh. The North Rim can be worse. Keep in mind that visitor services and facilities inside the park on the North Rim are closed from mid-October until mid-May and although visitors can still visit the North Rim, the road from Jacob Lake to the North Rim (Highway 67) is subject to closure due to snow.

Services and some facilities at the South Rim are open all year, but be prepared for cold temperatures, snow, icy roads and possible road closures. However, the Ground Canyon is beautiful covered with winter snow.

Spring Weather & Temperatures.

By mid-April, winter weather usually begins to break, and although snow is not uncommon in May, warm spells become more frequent. The cold temperatures of winter usually give way to warming and a pleasant spring. If you prefer smaller crowds, the spring season is a good time visit the Canyon before school breaks for summer vacation.
