When to Go

Summer is the busiest season, with July experiencing the greatest crowds. However, a spring or fall visit gives you two advantages: fewer people and cooler temperatures. In summer, especially in years with little rainfall, daytime temperatures can reach into the 90s. A winter visit to the park brings even more solitude, as all but one section of campsites are shut down and only about 2 miles of South Rim Road, the park main road, are plowed.

November through March is when the snow hits, with an average of about 3 to 8 inches of it monthly. April through May and September and October are the rainiest, with about an inch of precipitation each month. June is generally the driest month. Temperatures at the bottom of the canyon are about 8 degrees warmer than at the rim.
