Arizona
The Grand Canyon State
Perfect desert weather exists here, just not in the months most people have off.
When to go
The best time to visit Arizona is March through April or October through November, when desert highs sit in the 70s and 80s F and the Grand Canyon, Sedona, and Phoenix are all pleasant at once.
Go in spring or fall. From March through April the desert blooms, Phoenix and Tucson run in the 80s F, spring training fills the ballparks, and the Grand Canyon's South Rim is cool but fully open. October and November are the mirror image: the summer furnace finally breaks, the crowds thin, and hiking weather returns everywhere from Sedona to Saguaro.
Summer in the low desert is the real deal-breaker: Phoenix regularly tops 110F from June into September, and hiking becomes genuinely dangerous by mid morning. The twist is that Arizona has a second story up high. Flagstaff, the canyon rims, and the White Mountains sit thousands of feet up, run 20 to 30 degrees cooler, and even get real snow, which is why winter here can mean saguaros in the morning and skiing by afternoon.
The claim to fame
What Arizona is known for
Season by season
The Arizona year
Spring
The headliner. Wildflowers and cactus blooms, 70s and 80s F in the desert, spring training through March. Book Sedona and canyon lodging months ahead; everyone knows this is the window.
Summer
Avoid the low desert: 105 to 115F in Phoenix and Tucson, plus dramatic monsoon storms from roughly late June through September. High country is the escape; Flagstaff summers run in the low 80s F.
Fall
Excellent and slightly underrated. By mid October the desert is back to the 80s F, crowds are lighter than spring, and aspens turn gold around Flagstaff in early October.
Winter
Phoenix and Tucson are the point: sunny 60s and 70s F while the rest of the country freezes, which is why snowbirds and golf pricing peak now. The Grand Canyon South Rim stays open and dusted with snow; the North Rim closes for the season.
The hit list
What to actually do
- 01Grand Canyon South Rim · Grand Canyon Village
Open year-round and worth every cliche. Sunrise at Mather Point beats sunset for crowds; below-the-rim hikes demand pre-dawn starts in warm months.
- 02Sedona red rocks · Sedona
Cathedral Rock and Devil's Bridge headline, but the town's trail network is enormous. Spring and fall weekends are jammed; go midweek.
- 03Antelope Canyon · Page, Navajo Nation
The famous slot canyon is guided-tour only through Navajo operators. Midday light is best; book well ahead.
- 04Horseshoe Bend · Page
A short walk to one of the Southwest's signature views of the Colorado River. Brutal at midday in summer, glorious near sunset.
- 05Monument Valley · Navajo Nation, Arizona-Utah line
The Old West of every movie. The 17-mile scenic drive is self-drivable; Navajo-guided tours reach the backcountry arches.
- 06Saguaro National Park · Tucson
Two districts flanking Tucson, thick with giant cacti. Late April into May catches the white saguaro blooms.
- 07Petrified Forest National Park · Holbrook
Painted Desert badlands littered with 200-million-year-old stone logs, right off I-40 and rarely crowded.
- 08Lowell Observatory and Flagstaff · Flagstaff
Where Pluto was discovered, in the world's first International Dark Sky City. A cool-aired base at 7,000 feet.
- 09Havasu Falls · Supai, Havasupai Reservation
Turquoise waterfalls deep in a canyon, reached only by a 10-mile hike with a hard-to-get tribal permit. Plan a year out.
- 10Tombstone and Bisbee · Cochise County
An easy southern loop: OK Corral theatrics in Tombstone, then Bisbee's artsy mining-town streets, both best October through April.

Events worth planning around
Traveling as a family
With kids in tow
- ◆The South Rim is the most kid-friendly big-ticket sight in the Southwest: paved rim trail, free shuttles, and a strong junior ranger program.
- ◆Summer family trips should flip to the high country: Flagstaff, Williams and the Grand Canyon Railway, and Bearizona wildlife park all run 20 to 30 degrees cooler than Phoenix.
- ◆For homeschool families, late fall and winter weekdays mean near-empty trails in Sedona and Saguaro plus superb dark-sky astronomy programs at Lowell Observatory.
Quick answers
Arizona FAQ
What is Arizona known for?
The Grand Canyon above all, plus Sedona's red rocks, saguaro cactus desert around Tucson, Monument Valley, spring training baseball, and reliably sunny winters that fill Phoenix with snowbirds.
When is the best time to visit Arizona?
March through April or October through November, when the desert runs in the 70s and 80s F and every region of the state is comfortable at once. Winter is superb for Phoenix and Tucson; summer belongs to the high country only.
How hot does Arizona actually get in summer?
Phoenix routinely hits 105 to 115F from June through early September, and the heat is dangerous for hiking after mid morning. Flagstaff and the canyon rims, a few thousand feet higher, stay in the 80s F.
Is the Grand Canyon open in winter?
The South Rim is open year-round and beautiful with snow, with highs often in the 40s F. The North Rim closes to vehicles from roughly December through mid May.
