อากาศSedona เดือนกันยายน

Late September into early October is the window regulars name for this part of Arizona: temperatures cooling, patterns fairly stable and mostly sunny, crowds thinning. Flagstaff sits at about 7,000 feet, which is the whole point — days near 25°C while the desert below is still hot, and nights dropping to about 13, cold enough that a jacket or fleece is wanted early and late, with freezing possible in the second half of the month. The third week of September is when aspen, oak and birch begin turning on the Grand Canyon's North Rim. Layers you can shed is the standing advice.

Sedona-forum threads on a February visit describe daytime highs as genuinely typically in the sixties with real sunshine, posters naming nights dropping into the thirties as the standard overnight swing. Regulars call any snow genuinely quick to melt by midday, several posters warning rocks turn slippery afterward, especially near caves and shaded ledges. Posters call rain the more likely alternative when snow doesn't fall, several regulars naming muddy trails as the real result either way. Regulars call December through February genuinely the best hiking stretch of the year here, several threads naming this the reason locals recommend winter over the brutal summer heat. Posters recommend real traction and caution on red rock after any precipitation, several regulars calling this standard given how slick the surface gets. The record: 13.9C days, -1C nights, 38.9mm across over 4 days and 58 percent humidity.

Sedona-forum threads on March weather call this genuinely one of the more popular months, posters describing daytime highs typically in the sixties to seventies Fahrenheit while nights turn noticeably chilly. Regulars call spring break a real crowd factor, March traffic and trailhead parking considered busy every day of the week though weekends run noticeably worse. Posters recommend booking accommodation well ahead given how far in advance March fills up, several regulars calling it genuine peak season locally. Regulars call Bell Rock, Boynton Canyon and Red Rock Crossing all solid March hikes, the Chapel of the Holy Cross and Tlaquepaque worthwhile non-hiking additions. Posters call solitude still findable in March for anyone willing to skip the most photographed viewpoints, real quiet available just off the busiest trails. The record: 17.2C days feeling like 16C, 1.7C nights, 45.2mm across nearly 6 days and 47 percent humidity.

Sedona-forum threads asking whether July is too hot describe daytime readings as commonly in the mid-nineties to low hundreds Fahrenheit, posters calling the low humidity at least some consolation. Regulars recommend hiking by sunrise and being finished before ten, the heat building fast enough that a midday trail attempt becomes genuinely risky. Posters call carrying far more water than feels necessary standing advice, dehydration here sneaking up quickly even on a short red-rock walk. Regulars recommend waiting until five or six before heading back out for a second round, the worst of the afternoon heat easing by then. Posters describe nights as genuinely pleasant by contrast, temperatures dropping into the sixties Fahrenheit and called wonderful after a scorching day. Regulars call the red rocks still worth the trip in July for anyone willing to plan around the heat. The record: 36C days feeling like 36C, 18.8C nights, 43.2mm across over 5 days and 40 percent humidity.

Sedona-forum threads asking if January is too cold get a nuanced answer: afternoons regularly reach comfortable temperatures in the 50s to 60s Fahrenheit under sunny skies, genuinely pleasant for hiking the red rock trails, but mornings and evenings drop to freezing or below, cold enough that layering matters more than the daytime high alone suggests. Posters describe the month as variable year to year - some Januarys pass with barely any snow, others bring a real blizzard severe enough to shut the town down for days. Regulars are consistent that heavy snow accumulating in Sedona itself, versus the surrounding higher terrain, is uncommon though it does happen. The standing advice is to check the specific week's forecast and pack for both a sunny hike and a genuinely cold snap. The record: 11.9C days feeling like 8C, -1.8C nights, 42mm across 4.8 days, a notably high 19.5cm of fresh snowfall, 61 percent humidity and 8.2 hours of sun.
