Zion National Park Weather

Zion National Park is considered a cool, semi-arid climate. The weather in Zion is therefore typically dry and hot, although the Park is known to experience occasional, heavy rainstorms. The landscape of the park is mostly shrubbery, forest, and grassland areas set against geological wonders.
Generally, people think of deserts as being hot but it gets quite cold during winter months, especially during the night. Based on what activities interest you, you should come at different times of the year. To make the most of your visit you should consider the season, temperature, precipitation, and sunrise and sunset times. These factors affect the adventures you can partake in at Zion National Park and are a big part of your overall experience.


Zion National Park is a part of the United States that experiences all four seasons. This constant climate change means the park is always changing as well. If you live in an area with all four seasons you already know how drastic the difference in the weather can be. You may feel as though you’ve experienced all four seasons in just one day.
The different seasons allow for a different visit depending on the time of year you would like to come. A visit in the winter and summer would be like exploring two totally different places
In addition to considering what activities you would like to do, you should also choose the timing of your visit based on your personal capabilities. If you have never been exposed to frigid temperatures, you should avoid visiting the park in the winter. Alternatively, if the hottest temperature you’ve experienced is a summer in the north, consider seeing Zion National Park in the spring or fall.


Zion National Park weather is no stranger to snow. In fact, the winters here are very similar to winter in many areas of the US. The weather and precipitation are not terribly extreme but can get very cold and snowy at times. Ice and snow may make hiking difficult unless your are very experienced with winter hiking and have the proper equipment.
Temperatures can vary by more than 30 degrees F in one day from the afternoon to night so you must be prepared if coming to the park during the winter.


Sometimes the spring in Zion offers a lot of rainfall. Since a portion of the spring is considered to be the rainy season you should anticipate at least a few showers during your visit, especially if you are planning a visit in March which is the rainiest month of the year. The temperature during spring is comfortable with cool mornings and nights with the warmest temperatures occurring midday.
Melting snow and water from rainfall leads to high water levels and mild flooding making water activities slightly more challenging. While the weather may be hit or miss, the beautiful blooming plant life and abundance of wildlife are not to be missed. As birds nest and hatchlings arrive and new wildlife is born you will have plenty of beautiful things to see so don’t forget your binoculars and camera!


While summer is the hottest season it is generally unusual for temperatures to be above 100 degrees F for extended periods. Summer monsoons raise the risk of flash flooding from the months of July to September because water is not quickly absorbed into the ground making for potentially dangerous conditions. This is not the norm and most summer days are hot but pleasant.
The summer months may be too hot for those not used to warmer weather. Make sure to prepare yourself for temperatures as high as 110 degrees F. Always pace yourself and stay hydrated to avoid illness and dehydration. You should also be sure to protect yourself from harsh UV rays by covering up and using high SPF products like sunscreen and UPF clothing. If you take care to know your limits in the summer months your trip to Zion National Park will be an enjoyable one!


Fall is the best, most temperate time to visit the Park. In the Fall, Zion National Park weather is a relief after a hot summer and there is far less rainfall than spring and summer. The changing season brings beautiful fall foliage for an aesthetic delight.
The river is colder which can make water activities a bit riskier. There is a very low risk of snow or ice meaning for hikers and explorers this is a great time to visit. When visiting Zion National Park in the fall be sure to bring your camera to capture the breathtaking colors of autumn.
