Zion National Park is Open
In summer, temperatures in Zion National Park often exceed 100°F/38°C. Zion experiences monsoons from mid-July into September that results in an increased risk of flash floods. Always be aware of the threat of storms and lightning and be prepared for a wide range of weather conditions. Check the weather forecast and know what to expect on the Weather and Climate page, or find out what it looks like now on the park webcam.

Flow Rate of the Virgin River
Most recent water temperature (11/17/2020): 42ºF/5ºC
The Narrows closes when the flow rate is over 150 cubic feet per second (CFS), or during spring snowmelt. The Narrows also closes when a Flash Flood Warning is issued by the National Weather Service, and remains closed for two hours after the warning is lifted. Check the weather before you head into a narrow canyon. Flash floods are always possible.
Pick a trail that is right for you from our hiking guide. Please check weather daily before hiking. Drink plenty of water during the summer heat. Temperatures can vary widely during each day. Carry and use layers to adapt to changing conditions.
