Best Time to Visit Grand Canyon National Park

Grand Canyon weather by month

Temperatures depend more on elevation than on the calendar. The South Rim sits around 7,000 feet, the North Rim around 8,300 feet, and Phantom Ranch at the bottom near 2,460 feet. NPS notes that temperature rises about 5.5°F for every 1,000 feet you drop, so a pleasant 65°F day on the rim can be well over 80°F at the river.

The table shows NPS average highs and lows for each spot. Use it to plan both what you wear on the rim and how far below the rim you hike.

What is open in fall 2026

Check current conditions before any trip this year, because two disasters have changed what you can do. On August 29, 2026, a flash flood in Bright Angel Canyon destroyed footbridges and damaged the Transcanyon Waterline that supplies the South Rim. NPS closed Phantom Ranch, Bright Angel Campground, the entire North Kaibab Trail, the South Kaibab Trail below the Tip-Off, and the Black and Silver bridges over the Colorado River. As of late September there is no estimated reopening date for those areas.

The water damage also halted overnight stays at every in-park hotel on the South Rim starting August 31, 2026, and Trailer Village is closed. Mather and Desert View campgrounds are open for dry camping only. NPS has said it tentatively expects to begin pumping water again by mid-November and to start a phased return of overnight services around Thanksgiving 2026, but those dates could change.

The park itself is open. Day visitors can still drive in, ride the shuttles, walk the Rim Trail and hike the upper Bright Angel and South Kaibab trails. Bring your own drinking water, because inner-canyon water stations are off and the park is under strict water restrictions.

Spring (March to May)

Spring is one of the two best windows. South Rim highs climb from about 51°F in March to 70°F in May, and May and June are usually the driest months of the year. Phantom Ranch averages 82°F in April and 92°F in May, which is the last stretch before the inner canyon gets dangerously hot.

Early spring can still bring snow and ice to the rim and the top of the trails, so pack traction devices in March and early April. Crowds build fast around spring break; NPS says to expect waits of up to two hours at the South Entrance between 9:30 a.m. and 4 p.m. during spring break and summer.

Summer (June to August)

Summer is the busiest and hottest season. The South Rim is comfortable, with highs in the low 80s°F, but average highs at Phantom Ranch run 101°F to 106°F and daytime temperatures in the inner canyon can exceed 110°F. NPS strongly discourages hiking below the rim between 10 a.m. and 4 p.m. in summer and warns never to try a rim-to-river-and-back hike in one day, especially from May to September.

To deal with the crowds, arrive at the South Entrance before 9:30 a.m. or after 4 p.m., use the free shuttles once you are inside, and watch sunrise or sunset when the rim is cooler and quieter. The Tusayan (Purple) shuttle, which lets you park outside the gate, runs only in summer.

Monsoon season (July to early September)

From July through early September, moist air from the south feeds afternoon thunderstorms. Mornings often start clear, clouds build by midday, and NPS says storms happen mainly between 11 a.m. and 6 p.m. August is the wettest month on the South Rim, averaging about 2.25 inches of rain.

Lightning is the main risk on the rim, which is exposed and high. Get off overlooks and out of the open when you hear thunder. Below the rim, storms cause flash floods and rockfall, and NPS warns that watersheds burned in the 2025 Dragon Bravo Fire are at higher risk of floods and debris flows. Plan hikes for early morning and be back on the rim by early afternoon.

• Start hikes at first light and turn around by late morning.
• Stay away from rim edges and isolated trees during lightning.
• Do not enter or cross drainages when it is raining upstream.

Fall (September to November)

Fall is the other best window. South Rim highs drop from 76°F in September to 65°F in October, and Phantom Ranch falls from 97°F to 84°F over the same months, so hiking conditions improve every week. Crowds thin after Labor Day, though weekends stay busy into October.

Free shuttles keep running through November 30, 2026, including the Hermit Road (Red) route. By November, nights on the rim fall into the 20s°F and the first snow is possible. For fall 2026 specifically, plan around the flood closures and the lack of in-park lodging described above.

Winter (December to February)

Winter is the quietest season on the South Rim. Highs average in the low 40s°F and lows near 20°F, and the South Rim gets about 58 inches of snow in an average year. Snow on the red rock makes for striking views, and you will share the overlooks with far fewer people.

Expect icy trails, especially the top sections of the Bright Angel and South Kaibab trails, so carry traction devices. Storms can close roads briefly and fog can hide the canyon for hours, so build a spare day into your plans. Hermit Road is open to private vehicles from December through February, which is the only time you can drive it yourself. Inner-canyon temperatures in winter are mild, in the 50s°F at Phantom Ranch.

South Rim vs. North Rim seasons

The South Rim is open 24 hours a day, all year. The North Rim is about 1,300 feet higher, gets roughly 142 inches of snow a year, and normally opens only from mid-May to mid-October for full services. The drive between the two rims is about 212 miles and takes about 4.5 hours.

The July 2025 Dragon Bravo Fire destroyed about 70 structures on the North Rim, including the historic Grand Canyon Lodge and the North Rim Visitor Center. For 2026, parts of the North Rim reopened on May 15 for a shorter, day-use season. There is no overnight lodging, no potable water anywhere on the North Rim, and the gas station closed for the season on September 19.

The North Rim Campground and General Store close October 15, 2026. Cape Royal Road and Point Imperial Road close from sunset October 15 through sunrise November 3 for road repairs. The North Rim stays open for day use through November 30, 2026, or until the first major snowstorm. The North Kaibab Trail, Bright Angel Point Trail, Widforss Trail and Transept Trail remain closed. NPS has not announced plans for the 2027 North Rim season yet.
