Preparing for Zion National Park – Weather Forecasts
Know before you go!
This is canyon country. Flash floods are a serious threat in Zion. July, August, and September are considered our “monsoon season” and therefore, flash floods are more likely to occur during this time of year. However, these powerful and potentially fatal floods can happen any time of the year. Your ambivalence and lack of information can kill you. Before you go, be sure you know! Stop by the Zion Backcountry desk or Zion Rock and Mountain Guides to find out the current weather conditions and patterns, flash flooding potential, and specific trail information.
