One consideration in deciding when to take a Grand Canyon river trip is the weather. When is it the coolest? The hottest? The wettest?
Temperatures vary in the Canyon just as they do everywhere. You will find the chart below helpful. It shows the average temperature and precipitation for March-October. Humidity is generally low, the water temperature is fairly consistent hovering around 50-55 degrees F during the summer. As the water temp is cold, rain gear is recommended, especially for early season whitewater trips, in the morning, and on cloudy days.
