Weather by month

Grand Canyon

Arizona

The rim sits high in ponderosa country with a genuine mountain winter, while the canyon floor below runs a summer entirely of its own.

The best time to come

May and September are the sweet spot — comfortable on the rim, manageable below it, and the North Rim open. October is beautiful and quiet, but the nights turn freezing and the North Rim shuts for the season.
