Utah’s weather changes a lot from month to month, and the differences across the state can be pretty dramatic. You’ll find everything from blazing hot desert summers to snowy mountain winters, so each month brings its own quirks that locals and visitors should probably know about.
Utah’s monthly weather swings from frigid January averages of 23°F to 37°F in Salt Lake City to scorching July highs hitting 92°F. Mountain towns like Park City stay much cooler, while desert spots like Saint George get really hot. This huge range happens because Utah sits at a high elevation and has all kinds of terrain—mountains, valleys, desert, you name it. Being in the western U.S., Utah gets a semi-arid climate with low humidity and some wild temperature shifts between seasons.
If you get a handle on Utah’s monthly weather, you can plan your adventures, pack the right clothes, and avoid surprises. Each part of the state feels different, with snowy peaks getting over 10 inches of snow per month in winter, while the desert barely gets any rain at all. Seasonal trends show up clearly, so some months are just better for certain outdoor stuff, and others need more prep for tough conditions.
Monthly Weather Overview in Utah
Utah’s temperatures swing wildly through the year. Summers can reach 100°F, while winters sometimes dip below zero. Most of the rain comes in the spring, and summers are usually bone dry with tons of sunshine.
Typical Temperature Ranges by Month
Winter brings the coldest days in Utah. January highs range from 30°F to 55°F, and some spots drop below zero at night. February stays cold, with highs between 32°F and 58°F.
Spring warms things up. March temps run from 40°F to 65°F, and April gets nicer with highs from 50°F to 75°F. By May, you’re looking at 60°F to 85°F.
Summer hits hard with serious heat. June climbs from 70°F to 95°F. July is the hottest, with highs between 80°F and 100°F. August cools off just a bit—think 75°F to 95°F.
Fall cools things down. September highs go from 65°F to 85°F. October feels pleasant, with 50°F to 75°F. By November, highs drop to 35°F to 55°F, and December chills things out at 20°F to 45°F.
Average Precipitation Patterns
Utah gets most of its rain in spring. From March to May, storms bring more moisture, especially up north and in the east.
Summer is the driest. August is the least rainy month. Thunderstorms sometimes roll through in the south, but they don’t last long.
Winter brings snow to the mountains. Salt Lake City averages about 60 inches each year. The Wasatch Range gets hammered with lake-effect snow—some places see up to 500 inches.
Cities like Salt Lake City and Provo log 48mm to 73mm of precipitation yearly. Rainy days spike in spring and fall compared to the dry summers.
Humidity and Sunshine Trends
Utah stays dry all year thanks to its semi-arid climate. Summers feel especially dry, even when it’s blazing hot. That low humidity actually makes the heat a lot more bearable.
Sunshine is pretty much a given most of the year. Summer days are long and bright. Winter days are shorter, but you’ll still get clear skies between storms.
Temperature inversions happen a lot in valley areas during winter. They trap fog and haze, cutting down the sunshine for a while. Valleys get this more than the mountains.
The high elevation means Utah sees big temperature swings between day and night, especially in the mountains.
Seasonal Weather Patterns and Climate
Utah’s four seasons really feel different, with big shifts in temperature and precipitation. The state’s mix of mountains and deserts keeps things interesting, moving from cold, snowy winters to hot, dry summers. Spring and fall bring milder, in-between weather.

Mountain vs. Valley Climate Differences
Elevation really changes things. Temperatures drop 3°F to 5°F for every 1,000 feet you climb.
Valleys trap cold air in winter, causing temperature inversions that make valleys colder than the nearby hills. Sometimes, you’ll see 20°F differences just a few miles apart.
Mountains get more precipitation—30 to 60 inches a year. Valleys see much less, usually 10 to 20 inches.
Winds behave differently, too. Mountain areas tend to get stronger, more unpredictable gusts. Valleys are calmer but can trap air for days at a time.

Weather Preparation Tips for Each Month
Utah’s wild seasonal changes and big elevation swings make preparation key.
Travelers need to plan their clothing layers carefully, since temperatures can change fast.
Knowing seasonal hazards helps everyone stay safe in both the mountains and the desert.
Recommended Clothing and Gear
Winter months (December-February) call for thermal base layers, insulated winter coats, and waterproof boots that can handle snow.
Temperatures can drop to 21°F, so you’ll want warm hats, gloves, and scarves for anything outdoors.
Spring transition (March-May) means you need layers you can mix and match.
A medium jacket over lighter shirts works well, since temperatures range from 34°F to 74°F.
Bring waterproof rain gear, too—spring showers show up pretty often.
Summer months (June-August) demand breathable fabrics and good sun protection.
Temperatures can reach 92°F, so lightweight shirts, shorts, and a wide-brimmed hat are smart choices.
Evenings can cool off by 20-30 degrees, so tossing in a light jacket is a good idea.
Fall season (September-November) mixes summer and winter gear.
Early fall days stay warm, but nights cool down quickly.
By November, you’ll need winter clothing again as temperatures can drop to 30°F.
Travel Safety and Seasonal Hazards
Mountain elevation changes can throw the weather for a loop, no matter the time of year. If you’re driving up high, pack emergency supplies—blankets, water, and some non-perishable snacks are a must.
Winter driving hazards sneak up on you with black ice and surprise snowstorms in the mountain passes. Utah actually requires snow tires or chains on a lot of roads from October through April, so don’t get caught unprepared.
Summer heat dangers hit hard in the desert, with temperatures easily topping 90°F. If you’re hiking, bring extra water, grab some electrolyte supplements, and honestly, try to stay out of the midday sun from 10 AM to 4 PM.
Flash flood risks show up fast during spring snowmelt or those wild summer thunderstorms. Canyons and low spots can flood before you even realize it, so keep an eye on the weather before you head out.
