The best time to visit Zion National Park can vary depending on your preferences and which parts you’d like to see, but we’d generally recommend going in the spring or fall. Summer is the most popular time to visit the park, which means it can get a bit crowded – especially on the weekends. Zion is also located in the middle of a desert, so the summer weather can get too hot for some people. Temperatures in July and August regularly reach 100 degrees Fahrenheit, so make sure you bring plenty of water if you visit over the summer. If the heat does become a little too much for you to handle, you can escape the sun by exploring the slot canyons and gorges.
On the flip side, winters in Zion National Park can get very cold due to the high elevation of the park. The daytime temperatures aren’t too bad – usually in the 50s during the winter – but camping in Zion can be difficult when the temperature drops below freezing at night. Zion National Park is known for being especially beautiful when covered in snow, but snowfall is actually relatively uncommon and accumulation is often melted by the rain that follows. If you’re hoping to do a little winter photography during your trip to Zion, watch the weather reports carefully and be prepared to get up early and catch the park when it’s still covered in unmelted snow.
Visiting during the spring and the fall allow you to avoid the most extreme temperatures, although you don’t get the added benefit of the snow on the mountains. These months also constitute the rainy seasons in Zion, so keep an eye out for flash flood alerts.
