Honestly, most folks driving up I-15 toward Zion or cruising down from Salt Lake City barely give Leeds a second glance. They see the red cliffs, the sagebrush, and a few historic stone buildings. They figure the weather in Leeds Utah is just a carbon copy of St. George or maybe a slightly cooler version of Cedar City.
You’ve probably done the same. But here’s the thing: Leeds is tucked into this weird, beautiful topographical "sweet spot" at about 3,480 feet. It’s not quite the low-desert furnace of the Dixie basin, yet it avoids the bone-chilling mountain freezes that trap Cedar City residents in their parkas for six months a year.
It’s the transition zone. Basically, if St. George is the "Palm Springs of Utah," Leeds is the backyard that actually gets a breeze.
The Reality of Summer: It’s Hot, But There’s a Catch
When people talk about the weather in Leeds Utah during July, they usually lead with the 100-degree days. Yeah, it gets hot. Average highs in July hit roughly $99^{\circ}F$, and we definitely see those $104^{\circ}F$ spikes that make you want to live inside your freezer.
But it’s a different kind of heat than you’ll find thirty minutes south. Because of the elevation and the way the breeze rolls off the Pine Valley Mountains, the nights actually cool down. While St. George might be sweating at $75^{\circ}F$ at midnight, Leeds often drops into the mid-60s. That’s a massive difference for your AC bill and your sanity.
Then there is the monsoon. Around late July and August, the wind shifts. It stops blowing from the dry Great Basin and starts pulling moisture from the Gulf of California.
- The sky turns a bruised purple.
- The smell of wet creosote and sage fills the air (the best smell on earth, period).
- Sudden, violent thunderstorms dump an inch of rain in twenty minutes.
If you’re out hiking nearby in the Silver Reef area or toward the Red Cliffs Recreation Area during this time, you have to be smart. Flash floods aren’t just a "maybe" here—they are a mathematical certainty in the slot canyons. If you see clouds over the mountains, even if it’s sunny where you’re standing, get out of the wash.

Winter is Surprisingly Gentle
I’ve had people ask me if they need a snowblower in Leeds. Short answer? No. Long answer? Only if you like having expensive garage ornaments.
The weather in Leeds Utah in the winter is remarkably mild compared to the rest of the state. While Salt Lake is buried in "lake effect" snow and the Wasatch Front deals with inversion smog, Leeds usually stays clear and crisp.
January highs hover around $52^{\circ}F$. Sure, it dips below freezing at night—averaging about $31^{\circ}F$—but the sun usually burns off the frost by 10:00 AM. You might get a light dusting of snow once or twice a year. It looks spectacular on the red rocks for about two hours, and then it’s gone. It’s "light jacket" weather, not "survival gear" weather.
Why the Wind Matters Here
There is one thing nobody tells you about Leeds: the wind. It’s not constant, but when a cold front moves through, the "gap" between the mountains creates a bit of a wind tunnel. April is historically the windiest month, with averages around 14 mph, but gusts can kick up much higher.

If you’re planning on gardening or setting up a patio, you’ve got to stake things down. The wind can be relentless for a day or two, then it completely vanishes, leaving you with a perfectly still, blue-sky day that feels like a postcard.
The Shoulder Seasons: Leeds at Its Best
If you want to experience the absolute peak of weather in Leeds Utah, you have to be here in May or October.
In May, the desert is still green from the spring rains. Wildflowers like the Desert Mallow and Indian Paintbrush pop up in the red dirt. Temperatures sit in the low 80s. It’s that perfect "goldilocks" zone where you can hike all day without needing three gallons of water.
October is arguably even better. The intense summer sun softens. The high-desert light turns golden and hits those cliffs in a way that makes every amateur photographer look like a pro. Highs stay in the mid-70s, and the air gets that sharp, clean autumn bite.
Actionable Tips for Navigating Leeds Weather
If you’re visiting or moving to the area, don’t just trust the generic "Southern Utah" forecast. Leeds has its own microclimate.
- Layers are non-negotiable. Because the daily temperature swing (the diurnal shift) can be $30^{\circ}F$ to $40^{\circ}F$, you’ll be shivering at the trailhead at 7:00 AM and stripping down to a t-shirt by noon.
- Hydrate before you feel thirsty. The humidity in June can drop to 20%. You won’t realize you’re sweating because it evaporates instantly. If your head starts to throb, you’re already behind.
- Check the "Flash Flood Potential" rating. The National Weather Service in Salt Lake City puts out a daily graphic for Southern Utah. If it says "Probable" or "Expected," stay out of the canyons.
- Watch the Pine Valley peaks. If you see snow sticking on the mountains to the west, expect the temperatures in Leeds to drop about five degrees lower than the forecast predicts as the cold air sinks into the valley.
Understanding the weather in Leeds Utah is really about respecting the transition. It’s a place where the Mojave Desert shakes hands with the Colorado Plateau. It’s rarely boring, usually sunny, and always demands that you pay attention to the sky.
Pack for the sun, but keep a hoodie in the trunk—you'll definitely need it once the sun dips behind those red ridges.
