The best time to visit the Grand Canyon is April to May or September to October, when the South Rim has average highs of 61 to 76 F. If you want fewer people, go from December to February and expect snow. We read the Park Service, NOAA and visitor count data on 15 October 2026.

Month by month: temperature and crowds

Note: Temperatures are NOAA 1991 to 2020 monthly normals from the NCEI data service, read 15 Oct 2026. The South Rim column is the GRAND CANYON NP 2 station at 6,785 feet. The North Rim column is the BRIGHT ANGEL RS station at about 8,350 feet, which NOAA's station list places on the North Rim. Phantom Ranch is the PHANTOM RCH station at 2,530 feet. Visitors are the Park Service's recreation visits for the whole park, averaged over 2023, 2024 and 2025, from its visitation service (irmaservices.nps.gov, read 15 Oct 2026). They include both rims

December43 / 1836 / 1756 / 36311,970Cold, few people. North Rim road closes 1 Dec

The Park Service gives this rule of thumb: temperature rises about 5.5 F for each 1,000 feet you go down (NPS weather page, updated 18 Feb 2025). It says the North Rim averages 142 inches of snow a year and the South Rim 58 inches.

Which month for which plan

  • Hiking below the rim: April, May, late September and October in a normal year. The NPS says rim lows are below freezing in April and May, and snow has been reported as late as mid-June (NPS weather page). In fall 2026 the main trails to the river are closed. See the Phantom Ranch section.

  • Fewest people: December to February.

  • Warm days on the rim: June to August, with highs in the 80s F, but this is also the busiest and stormiest time.

  • Fall: the NPS says rim highs fall from the 60s F in September to the 50s F by November.

South Rim and North Rim seasons

Note: The South Rim is open all year. Winter brings snow, cold, icy trails and shorter days. Roads can close in bad weather. The park uses rock cinders, not salt. The free South Rim shuttle runs in winter. The North Rim is closed to all vehicle traffic from 1 December to 14 May (NPS winter visits page, updated 21 Sep 2026, read 15 Oct 2026)

Hours: Fall 2026 South Rim shuttle, 12 Sep to 30 Nov: Village (Blue) route 7 a.m. to 9 p.m. Kaibab Rim (Orange) route from 6 a.m. until one hour after sunset. Hermits Rest (Red) route from 8 a.m., last bus one hour after sunset. Hermit Road is closed to private vehicles from 1 March to 30 November 2026. The Tusayan route returns in summer 2027 (NPS shuttle page, updated 11 Sep 2026, read 15 Oct 2026)

The shuttle times above are the fall schedule. We did not read the winter or spring schedule, so check the NPS page for the month you go.

North Rim in 2026

Note: The North Rim is open through 30 November 2026 or the first major snowstorm. Cape Royal Road and Point Imperial Road are closed from sunset 15 October to sunrise 3 November 2026 for road repair. The 2026 season is day use and limited backcountry access. Overnight lodging is not available. The NPS expects a phased return of services in 2027 and 2028 and beyond. The North Rim Campground closed for the season on the morning of 16 October by the Park Service's 30 September release, and the General Store closed on 15 October. The gas station closed on 19 September, so there is no fuel in the park. Lodging, food and fuel are about 45 miles north at Jacob Lake (NPS North Rim status page, updated 14 Oct 2026, and NPS news release of 30 Sep 2026, read 15 Oct 2026)

The status page says burned areas from the Dragon Bravo Fire are "more susceptible to hazards including debris flows," "particularly during or after rainstorms." It also refers to the former Grand Canyon Lodge site. Our Las Vegas page covers the fire and the drive: read it before you plan the North Rim.

We did not find a 2027 opening date. The 14 May date above is when the winter road closure ends, not a promise that services are open.

Phantom Ranch and the inner canyon

Note: Phantom Ranch, the Canteen and cabins, Bright Angel Campground, Cottonwood Campground, the North Kaibab Trail from the trailhead to Phantom Ranch, and the Black and Silver Bridges closed on 29 August 2026 after flash flooding. "There is no estimated reopening of these closure areas at this time." (NPS North Rim status page, updated 14 Oct 2026). The winter visits page lists Bright Angel Campground as closed through 4 January 2027 (updated 21 Sep 2026)

Note: On 3 September 2026 the Park Service also closed the South Kaibab Trail below the Tip-Off and the Bright Angel Trail below its junction with the Tonto Trail. "There is currently no estimated date for reopening these areas." (NPS news release, 3 Sep 2026, read 15 Oct 2026)

Together these close the main trails from both rims to the river. We did not check the upper parts of the two South Rim trails or other trails into the canyon, and we did not check whether Phantom Ranch can be booked for 2027. Check the NPS trail page before you book a night below the rim.

Heat is the other limit. The NPS lists inner canyon averages of 101 F in June, 106 F in July and 103 F in August, and says summer highs can top 120 F (NPS weather dangers page, updated 12 Mar 2025). NOAA's Phantom Ranch normal for July is a 104 F high. The two sources use different stations, so the numbers differ by a few degrees.

Monsoon season

Note: Severe thunderstorms can form quickly from July to mid-September. The NPS says storms occur mainly from 11 a.m. to 6 p.m. in July, August and early September, and that flash flood risk exists any time rain is forecast. Hikers have died in floods from storms as far as 25 miles away. "Lightning can strike 10 miles across the canyon," so being below the rim does not protect you (NPS weather and weather dangers pages, read 15 Oct 2026)

Start hikes early in July and August and plan to be off exposed ground by late morning. The NPS says summer rains usually ease in mid-September.

Winter snow

The NPS says the rim gets about 50 to over 100 inches of snow a year and that winter weather usually begins by November. Snow is possible at higher elevations through April. South Rim winter lows are generally in the teens F and highs in the 40s F. Buy over-the-shoe traction devices in the village if you plan to walk the rim trail.

The worst time to go

For most people it is July. It is the busiest month, at 518,381 visits, the rim is in the 80s F, thunderstorms start, and the inner canyon is past 100 F. For a hike to the river, the cooler months are the safer choice once the trails reopen. For the North Rim, the worst time is any time between 1 December and 14 May, when the road is closed. In 2026 it is also a poor choice if you need a bed, because there is no lodging.

Events

We did not find an NPS-listed festival or event for the Grand Canyon that affects the season, so we do not list any. Holiday weekends are not covered by a source we read. This is not confirmed.

What we checked and what can change

Checked on 15 October 2026: NOAA's 1991 to 2020 monthly normals through the NCEI data service for three stations. The NPS visitation service for 2023 to 2025. The NPS pages on weather (18 February 2025), weather dangers (12 March 2025), winter visits (21 September 2026), shuttle buses (11 September 2026), the North Rim status page (14 October 2026), the 30 September 2026 North Rim news release and the 3 September 2026 inner canyon closure release. Station elevations come from NOAA's GHCN station list. The NPS statistics page says total park visits were 4,430,653 in 2025, updated 28 July 2026.

Not confirmed: events, a 2027 North Rim opening date, when Phantom Ranch and the lower Bright Angel and South Kaibab trails will reopen, the winter and spring shuttle schedules, and any lodging price or availability. Normals are 30-year averages, not forecasts. Visitor counts are for the whole park and are not split by rim. The closure dates above can change with weather and flood damage, so check the NPS conditions page before you go.
