Zion Weather and Conditions

Weather is the variable that reshapes a Zion day. This page lays out the seasonal patterns you can plan around, and points to the forecast and road sources that tell you what is actually happening.

The Seasonal Pattern on the Canyon Floor

These typical highs are for the canyon floor near Springdale, at about 4,000 feet. Higher country such as Kolob Terrace runs 10 to 20°F cooler.

  • Spring, March to May: highs from about 60 to 85°F, with the river swollen by snowmelt.
  • Summer, June to August: highs from about 93 to 100°F, with July the hottest month.
  • Fall, September to November: highs from about 63 to 91°F, with mild days and cool nights by October.
  • Winter, December to February: highs from about 52 to 57°F, with nights that drop below freezing.

Weather That Changes the Plan

Monsoon season

July through September brings afternoon thunderstorms, and the danger in a slot canyon is flash flooding from rain that fell somewhere you cannot see. Read the forecast the morning of any Narrows or Subway hike, and rethink the day if storms are in the outlook. Our Narrows guide covers the hike itself.

Heat

On summer afternoons the canyon floor can pass 100°F. The answer is timing: start at dawn, carry more water than you think you need, and rest through the worst of the afternoon.

Cold and ice

Winter nights fall below freezing, so layer up and plan for short days. Trail ice details are in trail updates; for the full winter picture, read Zion in winter.

Roads

Check the UDOT source above before you leave, and check whether any road or route is closed. [VERIFY: nps.gov]
