Moving to St. George: What is the Weather Like Through the Year in St. George?

Choosing to move to a new place is a decision you'll want to make with as much information as possible. If you're considering a move to St. George, you might be wondering what the weather is like. Utah is known for mild summer and cold, snowy winters, but St. George is an exception and this part of the state has a totally different climate. Here's what you should know. 

Hot, Dry Summers

Our summers here are more like what you probably imagine when you think of Arizona than the typical impression of Utah. St. George is located in southern Utah’s desert region, meaning summers are long, hot, and dry. From June to September, temperatures regularly exceed 100°F (37°C), with some days reaching as high as 110°F+ (43°C).

Keep in mind that the dry heat can feel more bearable than humid heat, but it can still be intense. For most homeowners, air conditioning that works well and efficiently is essential during the summer months. 

Mild, Comfortable Winters

You probably think of loads of snow in a Utah winter, but St. George is different in this area, too. In fact, one of the biggest draws to St. George is its mild winter weather. Unlike other parts of Utah that see heavy snowfall, St. George rarely experiences freezing temperatures. Daytime highs in winter (December–February) range from 55–65°F (13–18°C), with nighttime lows occasionally dipping into the 30s (0–4°C).

It’s an ideal escape for those who dislike harsh winters, perfect for people who want to enjoy hiking, biking, and golf year-round.

Low Humidity and Abundant Sunshine

St. George enjoys over 300 sunny days per year. Whether you're looking for a place to enjoy an active retirement or you want to put down roots in a place where spending time outside is easy, St. George is a paradise for anyone who loves sunshine. The low humidity makes even warmer temperatures feel more comfortable compared to humid regions.

With so many national parks and gorgeous outdoor places to explore nearby, you'll love having so much time throughout the year to take advantage of sunny weather.

Rain & Flash Flooding

Occasionally, St. George does get some big rain storms. St. George is in a desert climate, so we don't receive much rainfall—only about 8–10 inches per year. However, when it does rain, it can come in sudden, heavy downpours, especially during the monsoon season (July–September).

Before you buy a home, you should check if the property is in a flood-prone area. It's wise to have the right insurance set up and be prepared in case of flash flood warnings. Flash floods can happen quickly in low-lying areas and slot canyons, and some roads may flood and be temporarily blocked. Just keep these things in mind as you're choosing your new home's location. 

Wind & Dust Storms

Wind is a common occurrence in spring and fall, sometimes bringing dust storms, especially in open desert areas. While they aren’t as severe as those in some southwestern states, strong winds can kick up dust, reduce visibility, and affect allergies. With this in mind, you'll want to make sure the home you buy is air tight both for energy efficiency and blocking out dust when necessary.

Water & Drought Concerns

Like much of the Southwest, St. George deals with water conservation challenges due to its desert climate. While the city has a well-managed water supply, residents are still encouraged to use water efficiently.

In light of this, some HOAs have restrictions on grass lawns due to water conservation efforts. Xeriscaping (low-water landscaping) is popular and encouraged, and you might also consider water-efficient appliances and irrigation systems.
