Temperatures can vary, but the following chart shows average temperature and precipitation for the months of March through October. Water temperatures in the Colorado River average 50° year round, although side streams and waterfalls where we occasionally stop for hikes can be much warmer.

Weather forecast for Colorado River vs. Grand Canyon Rim

Finding the right weather forecast for the Colorado River can be tricky as most sources will report weather on the Rim of Grand Canyon vs. 5,000 feet lower along the river. That elevation can make a big difference!

Since weather conditions can be unpredictable and river water in the Grand Canyon is 52°, we recommend having a two-piece rain suit available during the day. You may wish to fold it tightly and keep it in your personal day-use dry bag.
