Visiting Moab in Summer
Triple digit heat, the year's thinnest crowds, and a river warm enough to swim in. Here's how to time your days, pick the right activities, and still come home with the trip you pictured.
A Typical July Day, Hour by Hour
The single most useful thing to understand about summer in Moab: it isn't one hot day, it's two short cool windows wrapped around a long dangerous one.
Is Summer a Good Time to Visit Moab?
Summer in Moab is a season of extremes, and it rewards visitors who plan around that honestly rather than around a postcard version of the trip. From late June through August, daytime highs routinely clear 100°F, and heat waves can push past 110°F. That heat makes midday hiking genuinely dangerous rather than just unpleasant, which means your itinerary needs to be built around early mornings and evenings rather than the leisurely all day pace that works in April or October.
The upside is real. The Colorado River warms into the comfortable 60s and 70s by midsummer, so rafting and paddleboarding trips stop being a cold water endurance test and start being genuinely refreshing. Days are long, sunsets stretch past 8 PM, and crowds at nearly every trailhead and overlook drop well below spring levels. If your schedule only allows a summer trip, or you'd rather float a river than climb a trail, Moab still delivers. If your calendar is flexible, our full month by month guide can help you compare summer against spring and fall before you book.
Slickrock and canyon walls radiate heat back at you long after the sun passes overhead. A "105°F" afternoon on exposed sandstone can feel closer to 115–120°F at ground level. Shade and water access matter more than the thermometer.
The three summer months aren't identical. Early June still carries some of late spring's mild mornings, while July and August deliver the year's most extreme and most consistent heat, plus the arrival of the North American monsoon. For a deeper, week by week breakdown, see our dedicated guides to June, July, and August.
What's the Weather Like in Moab During Summer?
Summer weather follows a predictable arc, but the intensity builds fast as the season goes on. Here's how the three months stack up against each other, and where to point yourself for more detail on each.
| Month | Typical High | Typical Low | What Defines It | Full Guide |
|---|---|---|---|---|
| June | 90–100°F | Mid 50s–60s | Transition month; first half still spring like, second half turns hot and dry | June guide → |
| July | 100–108°F | Mid 60s–70s | Peak heat begins; monsoon storms start appearing by late month | July guide → |
| August | 98–106°F | Mid 60s–70s | Still extreme, but afternoon storms bring brief relief and dramatic skies | August guide → |
Elevation offers a partial escape. Dead Horse Point State Park sits roughly 2,000 feet above town, which is good for about 10°F of relief; useful, but not enough on its own to turn a dangerous afternoon into a comfortable one. The La Sal Mountains run 20 to 30°F cooler than the valley floor, though reaching them eats into your available daylight. Deep, shaded canyons and the river corridor tend to be the more practical cooling options for a day trip.
From late July through August, afternoon thunderstorms build over the mountains and drift into the Moab area, usually between 2 and 6 PM. They can trigger flash flooding in slot canyons and washes within minutes. Check the forecast before any canyon hike or canyoneering trip, and always have a plan to reach higher ground quickly.
How Crowded Is Moab During Summer?
This is the part that surprises first time visitors: summer is one of the quietest seasons in Moab, not the busiest. Spring break and school field trip season load up March through May, and once the heat sets in, a lot of that traffic shifts toward mountain or coastal destinations instead. The result is shorter lines at popular trailheads, easier campsite availability, and a noticeably calmer Arches National Park and Canyonlands National Park than you'd find in April.
The one exception is the Fourth of July weekend, when regional visitors from Utah, Colorado, and Nevada fill hotels and campgrounds well in advance and river traffic spikes. Outside that single weekend, weekday and weekend crowd levels stay close to each other all summer, so you don't need to chase weekday timing as aggressively as you would in peak season. Tour and rafting operators shift their focus almost entirely to water based trips in summer, so booking a couple of weeks ahead for weekend river departures is smart, while hiking focused tours become easy to find on short notice since demand drops off with the heat.
Best Things to Do in Moab During Summer
Heat reshuffles the whole activity list. Water based trips move to the top, hiking becomes a sunrise only proposition on exposed trails, and a handful of shaded or high elevation options fill the gap in between. Here's where to put your time.
River Rafting
Warm water, long daylight, and no wetsuit required. Half day floats through Professor Valley and full day whitewater through Westwater or Fisher Towers are the single best heat strategy in Moab.
Compare rafting trips →Paddleboarding & Kayaking
Calm water near Highway 128 lets you set your own pace and swim whenever you overheat, best in the softer light of morning or early evening.
See paddleboard options →Sunrise Hiking
Delicate Arch becomes a headlamp start hike in summer: on the trail before dawn, at the arch as the sun rises, back to the car by 8 or 9 AM.
Plan the Delicate Arch hike →Guided Canyoneering
Narrow, shaded slot canyons run noticeably cooler than exposed trails. Guided technical routes are the smartest way to get real canyon adventure without the midday heat risk.
Browse canyoneering tours →Mountain Biking
Slickrock gets too hot to touch by midday. First light starts, extra water, and a willingness to cut a ride short are non negotiable for summer riders.
See summer trail picks →Scenic Overlooks & Parks
Air conditioned driving between overlooks at Arches, Canyonlands, and Dead Horse Point lets you take in the scale of the landscape without the physical strain of a midday hike.
Explore the national parks →Evenings deserve their own plan, too. Sunset at Dead Horse Point, patio dinners as temperatures drop into the 80s, and stargazing under a moonless sky all take advantage of summer's most pleasant hours. For age specific and rainy day style options, our seasonal activities guide and family activities guide break things down further, and the full Things to Do hub covers everything in one place.

Planning Your Summer Trip: Lodging, Camping & Booking Timing
Summer logistics differ from the rest of the year in one big way: demand drops, but the margin for error on cooling and hydration shrinks. Plan around both.
Lodging. Most hotels have solid availability even a week or two out, with rates typically well below spring pricing, except over the Fourth of July weekend, which books out months in advance like a spring holiday. Reliable air conditioning matters more in July than in any other month, so it's worth reading recent reviews for AC complaints before booking. Compare properties on our lodging hub, or go straight to hotels or resorts if you want a firmer comfort guarantee.
Camping. Developed campgrounds rarely fill to capacity in summer outside the holiday weekend, but overnight lows at lower elevation sites can stay above 75°F, which makes tent sleeping rough even with good airflow. RVs with working AC or campgrounds at higher elevation tend to sleep better. See our RV parks guide and campgrounds guide for specific properties.
Booking tours. River trips can sell out on summer weekends even though overall visitation is down, since demand concentrates so heavily on the water. Two to four weeks out is a safe window for a Saturday or Sunday departure; weekday trips are usually easier to book on short notice.
A car's interior can exceed 140°F in direct summer sun. Never leave electronics, medication, or pets inside, and carry extra water in the vehicle in case of a breakdown on a remote road.
What to Pack for Summer in Moab
Sun Protection
Wide brimmed hat, wraparound UV sunglasses, and SPF 50+ sunscreen reapplied every two hours. Sunburn can happen in under 30 minutes at this elevation.
Hydration
Three to four liters of water per person for any hike, plus electrolyte tablets. A hydration bladder encourages more frequent sipping than a bottle.
Clothing
Light colored, lightweight long sleeve layers with built in SPF, plus a packable layer for predawn starts when it can still be in the 60s.
Footwear
Breathable trail shoes for hiking, plus water sandals or old sneakers for river days so your hiking boots stay dry for the rest of the trip.
Frequently Asked Questions About Summer in Moab
Is Moab too hot in summer?
Summer temperatures regularly exceed 100°F and can push past 110°F during heat waves, making midday hiking genuinely dangerous rather than just uncomfortable. Summer becomes manageable once you restructure your schedule around it: start outdoor activities at dawn, move to water based trips or air conditioning through midday, and resume outdoor plans in the evening. Visitors who want to hike extensively during regular daytime hours are usually happier in spring or fall.
How crowded is Moab during summer?
Lighter than most visitors expect. Summer sees noticeably fewer visitors than spring at most trailheads and park entrances, with the Fourth of July weekend as the one significant exception. Weekday versus weekend crowd differences are also smaller in summer than in peak season.
Do I need to book hotels in advance for summer?
Not as far ahead as you would for spring, with one exception. Regular summer weeks typically have solid availability with a week or two of notice, but the Fourth of July weekend books up months in advance. See our lodging guide for current property options.
What are the best hikes in Moab during summer?
Anything you can finish before mid morning. Delicate Arch works well as a sunrise hike, and shaded canyon routes stay more tolerable later in the day than exposed slickrock trails. For a fully guided option that manages the heat and logistics for you, guided canyoneering trips through shaded slot canyons are a strong alternative.
Are summer thunderstorms dangerous in Moab?
They can be. Monsoon storms typically arrive between 2 and 6 PM from late July through August and can cause flash flooding in slot canyons and washes within minutes, along with lightning and strong wind. Check the forecast before canyon hikes or canyoneering trips and have an exit plan to higher ground.
Beat the Heat on the Colorado River
When the slickrock is too hot to touch, the river is exactly where you want to be. Compare half day floats and full day whitewater trips and lock in your summer dates.
