If you are planning a trip to Zion National Park, one of your big questions is probably “What will the weather be like when we get there?” When most people think of desert climates, they picture hot and dry. While we definitely have our fair share of that June, July, and August, we also have four very distinct seasons. Depending upon the month of your visit, there are certain things you should do to prepare and certain precautions you should take to be ready for the elements.

The weather can vary greatly during the months of March-May. On average, Zion receives the most precipitation in March. Daily average temps are 63°F in March, 73°F in April, and 83°F in May. During the course of a day, temps can vary up to 30°F, so dressing with layers is the answer to being prepared for a day out during the Spring. Having a raincoat or poncho in your daypack certainly wouldn’t hurt either! This is one of my favorite daypacks:

The summer months (June-September) are the hottest months in the park, with average temperatures being in the 90s. Not necessarily the driest though, with July-September commonly having afternoon thunderstorms that can cause large flash floods throughout the park. To prepare for Zion in the summer, make sure you have sun hats, sunscreen, and are drinking plenty of water and eating at least some salty snacks. You may not feel like you are sweating because of the lack of humidity, but you definitely are. If there is a thunderstorm in the forecast, stay out of canyons, creek beds, and away from the river. Bottled water is not sold inside the park. There are numerous refill stations for your water bottle or pack bladder. My Hyro Flask has survived miles of hiking adventures.

Fall is an ideal time for outdoor adventures in Zion. The temperatures have begun to drop, with daily highs in the 60s and 70s. Temperatures can drop significantly at night, so make sure you have layers to keep warm as the sun goes down. Rain can still bring flash floods, so always be sure to check the forecast before heading into canyons. Hydration is still imperative because of dry conditions.

Winters in Zion are commonly cold and wet, with the majority of our precipitation falling during December through February. December is the coldest month of the year here, with average daily temps in the low 40s. To prepare for a day out in this Winter wonderland, make sure you have shoes suitable for snow and ice, as well as a warm jacket, hat and gloves. There may be road and trail closures for several days after a storm while snow and ice melt. Always check trail conditions at the Zion National Park Visitor center.

Regardless of what time of year you choose to visit Zion you can have a wonderful, safe time by taking a few precautions and being prepared for the elements. Hydration is ALWAYS vital in our dry climate! Wearing clothing appropriate to the temperatures and your activities will go a long way toward helping you enjoy your time here.
