Weather and Average Temperatures At The Grand Canyon South Rim

Last updated on April 29, 2026.

Grand Canyon South Rim offers four distinct seasons, dramatic elevation changes, and some of the most varied travel weather in Arizona. Sitting around 7,000 feet above sea level, the South Rim is cooler than Phoenix, Tucson, and many lower desert destinations, with snowy winters, mild springs, warm summers, and crisp fall days. Understanding average temperatures and seasonal conditions helps travelers plan hiking, scenic drives, photography, lodging, and the best time to experience the canyon comfortably.

The South Rim of the Grand Canyon covers about 26 miles along Desert View Drive. Elevations range from about 6,900 to 7,600 feet depending on location, so average temperatures can vary slightly. It is strikingly beautiful at any season although temperatures can vary significantly. During winter months into early spring, the Canyon can be covered with snow creating outstanding views.

Best Times To Visit The Grand Canyon South Rim

Spring (March to May): One of the best seasons for mild daytime temperatures, blooming landscapes, and lighter crowds before peak summer travel.
Summer (June to August): Warm days and the busiest season. Excellent for families and long daylight hours, but arrive early and expect crowds. Afternoon thunderstorms are common in mid-to-late summer.
Fall (September to October): Outstanding weather with cooler temperatures, fewer crowds, and excellent visibility for photography and scenic overlooks.
Winter (November to February): Beautiful snow-dusted canyon views, quieter travel season, and lower crowds. Prepare for cold mornings, icy roads, and occasional storms.

Spring Weather and Temperatures At The South Rim

By mid-April, winter weather usually begins to break, and although snow is not uncommon in May, warm spells become more frequent. The cold winter temperatures give way to warming and a pleasant spring. This is a great time to visit the Canyon if you prefer smaller crowds since schools usually do not break for summer vacation until late May.

Summers At The South Rim

You will discover the largest crowds during the summer months. Summer temperatures are quite pleasant. If you plan on hiking or riding mules into the depths of the canyon temperatures can rise dramatically. You must dress accordingly in layers and carry an adequate supply of drinking water.

Summer Monsoon Storm Season

Summer thunderstorms frequently occur during July, August, and early September with potential for torrential rains, frequent lightning, and sudden flash floods at the canyon floor. Thunderstorms are variable in intensity and are more likely to occur mainly between 11 AM and 6 PM. Some of these storms can reach severe levels, with large hail and strong winds.

Fall Temperatures At The South Rim

Summer heat gives way to cooler temperatures during the fall months of September and October with progressively cooler temperatures into the later fall periods. Potential for summer rains typically diminish in early September. However, late summer thunderstorms or early winter snow storms have been known to take place during season transition creating sudden changes in temperature.

South Rim Winter Weather

Winter weather conditions on the South Rim can be harsh. However, the Grand Canyon is beautiful when covered with winter 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. Dress in layers since very chilly morning hours become warmer as the day progresses.
