Everyone wants to know when the “best” time to raft the Grand Canyon is. This question really has no answer because every month is different and every year is different. In general the commercial river season starts in April. April weather in general is spectacular, but it can be down right chilly and is often a little windy. May, June, and the first half of July tend to be clear and hot. During this time the river is generally green and the Little Colorado is usually not flooding. About the middle of July the monsoon season starts. The afternoon rain tends to cool off the hot days a little bit, gives the opportunity to see rimfalls, and returns the Colorado River to the pre-dam natural state of a red river. Colorado, after all, is a spanish word for red. Toward the third week of August, the monsoon season tapers off, and the weather tends to become drier again. September you begin to loose light as the autumnal equinox is around the 21st of September. This cuts into your daylight a little bit, meaning a little less hiking, but the weather is great. October is another good month other than the loss of daylight. Below, are some common questions about the weather that can help you make a decision based on your schedule and needs.
