I would probably choose to go in the fall because the days are usually clear and mild; nights are often cool. Autumn color displays begin in September in the high country. Colors in Zion Canyon usually peak in late October.



Zion's weather is very unpredictable. Precipitation peaks in March. Summer days are hot 95-110掳F. Winter in Zion Canyon is fairly mild, but the nights are often in the 20s and 30s.When is the best time to go back to Zion to do some canyoneering?
Summer, but be sure to check weather conditions first! If there's any rain, don't go!When is the best time to go back to Zion to do some canyoneering?
It really depends on the hike, the weather that week, and the year.



It depends on the current snowpack, the current temperatures, rain, etc.



I'd probably avoid it before early or mid May. There are lots of slot canyons that retain snow because they see so little light.



That said, you can show up and pick and choose your hikes based on the weather conditions. You can't really go wrong in June, July, or August. Some hikes require passes and have a daily limit, so you might want to start looking into what you want to do there and planning accordingly.
