Temperatures at the top of the canyon can be freezing in winter, while the bottom can feel like an oven in summer.

In this guide, you’ll find a month-by-month breakdown of Grand Canyon temperatures, seasonal tips for the South Rim, North Rim, and Inner Canyon, plus advice on the best time to visit and raft the Colorado River. Read on to learn more!
