Capitol Reef National Park Weather by Month: What to Expect Year-Round
Month-by-month temperatures, precipitation, crowds, and what's open at Capitol Reef.
Last verified against official NPS sources
Capitol Reef sits at 5,500 feet in south-central Utah's red rock country, and weather here swings hard with season. Winter nights dip below freezing; summer days top 90°F. Most visitors come in spring and fall when daytime highs sit in the 60–80°F range. Understanding what each month delivers—heat, rain, crowds, and whether you'll hike in shorts or down—helps you pack right and pick the season that matches your trip.
The park is open year-round, 24 hours daily. Current alerts include Stage II fire restrictions (no campfires) and elevated E. coli in the Fremont River. Higher elevations run 5–10°F colder than the visitor station; bring layers for any ridge hike.
Weather by Month
Temperature and precipitation data below are from NOAA climate normals (1991–2020) recorded at Capitol Reef National Park, 5,500 ft elevation. Higher elevations within the park experience cooler temperatures and more variable snow.

| February | 47°F | 26°F | 0.5 in precip / 1.5 in snow |
| March | 57°F | 34°F | 0.5 in precip / 1.7 in snow |
| April | 65°F | 39°F | 0.5 in precip |
| May | 74°F | 48°F | 0.7 in precip |
| June | 86°F | 58°F | 0.3 in precip |
| July | 91°F | 65°F | 1.0 in precip |
| August | 88°F | 63°F | 1.1 in precip |
| September | 80°F | 55°F | 0.9 in precip |
| October | 66°F | 43°F | 0.9 in precip |

Data: Capitol Reef Np, Ut Us, 5,500 ft (NOAA 1991-2020 normals, station USC00421171). Higher elevations run colder.
Spring (March–May)
Temperatures climb steadily from near-freezing lows in March to comfortable mid-70s by late May. March still sees occasional snow at higher elevations, but trails dry quickly. April and May are Capitol Reef's sweet spot—daytime highs perfect for hiking (65–74°F), nights cool enough for comfort (39–48°F). Wildflower blooms peak in late April and May across riparian zones and red rock slopes. Rainfall remains modest (0.46–0.65 inches monthly). Crowds build visibly as May approaches.
Summer (June–August)
Heat dominates. Daytime highs climb from 86°F in June to 91°F in July, then hold in the upper 80s in August. Nights remain in the low-to-mid 60s, offering some relief. July and August bring afternoon thunderstorms (1+ inch monthly precipitation total)—brief, localized downpours that drench one canyon while missing another a mile away. Humidity is low, but the heat limits comfortable hiking to early morning and evening. Peak visitation and camping demand occur June through August; expect crowded trailheads and full campgrounds.
Fall (September–November)
Temperatures drop steadily—September starts around 80°F, cooling to 51°F by November. Days remain excellent for hiking; nights increasingly chilly. Cottonwoods and willows along the Fremont River turn gold in late October, though Capitol Reef's desert landscape offers subtler color changes than northern parks. Rainfall increases slightly in September and October (0.87–0.95 inches monthly), feeding wildflower blooms. Crowds drop noticeably after Labor Day, making this one of the best times to visit. November can bring early snow and occasional rain, but is typically mild and dry.
Winter (December–February)
Overnight lows consistently fall below freezing; January and February average 20–26°F. Snow totals are modest overall (1.5–3.8 inches monthly at base elevation), but north-facing slopes and higher elevations accumulate more. Daytime highs remain in the 40–47°F range—cool but often sunny and clear. December is the driest month (0.37 inches precipitation). The park remains open and accessible year-round. Roads rarely close due to snow, but call the visitor center or check conditions before driving high-elevation spurs after a winter storm.
Best Seasons to Visit
April–May and September–October are ideal for most visitors. Temperatures are mild (65–80°F), crowds moderate to manageable, and trails are in good condition. June–August peak in visitation but bring heat and afternoon thunderstorms. Winter offers solitude and clear skies but requires cold-weather gear. March and November are variable—pleasant days alternating with cold, wet weather—but far less crowded than peak season.
Fire Restrictions & Water Safety
Stage II fire restrictions are in effect. Campfires, including charcoal, are prohibited even in established fire rings. Smoking is allowed only inside enclosed vehicles. Gas or liquid-fueled portable camp stoves are still permitted. The Fremont River currently tests positive for elevated E. coli levels. Do not enter the water or submerge your head; wash hands thoroughly with soap and water if any contact occurs. Ask the visitor center (435-425-3791) for updates on both restrictions and water quality before your trip.
Access & Visitor Information
Capitol Reef is open 24 hours daily, year-round. The visitor center is open daily except major holidays; call 435-425-3791 to confirm hours before you visit. Entrance is $20 per private vehicle, $15 per motorcycle, or $10 per person (bicycle, pedestrian). The park sits at 5,500 feet elevation; upper ridges and higher canyons run 5–10°F colder, so pack additional layers for any hike above the Scenic Drive. Cell service is limited throughout the park.
Common Questions
When is Capitol Reef too hot to hike comfortably?
July and August exceed 88°F most days. Start hikes by 8 am to finish before midday heat. High-elevation routes (above 7,000 ft) run 10–15°F cooler and remain hikeable into early summer. Stick to canyon bottoms and shaded drainages in peak heat.
Is the park open and accessible in winter?
Yes. Capitol Reef is open 24 hours year-round. Winter nights reach 20–26°F, and snow is light (1–4 inches monthly at the visitor station). Main park roads rarely close, but high-elevation spurs may require 4WD or chains after storms. Call 435-425-3791 for road conditions before driving remote areas.
Can I have a campfire in the park?
No, not currently. Stage II fire restrictions prohibit all campfires, including in established rings. Gas and liquid-fueled portable stoves are permitted. Check with the visitor center for updates on when restrictions may lift.
When do wildflowers peak at Capitol Reef?
Late April and May peak for spring wildflowers on red rock slopes and riparian zones. Fall wildflowers appear mid-September through October but are typically less showy. Summer thunderstorms can trigger late-summer blooms in isolated locations.
Is it safe to swim in the Fremont River?
No, currently not safe. The river shows elevated E. coli levels. Avoid submerging your head and wash hands with soap and water after any contact. The condition may improve seasonally; ask the visitor center for the latest water-quality status.
