อากาศแฟลกสแตฟฟ์ เดือนมกราคม

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.

Forum posters cite an average March daytime high around 43F with nighttime lows in the teens, describing March as still genuinely winter in Flagstaff - posters are direct that snow at some point during the month is close to guaranteed, unless an unusually warm stretch arrives early. Posters describe a typical late-winter snowfall here as brief, usually gone within a day or two, with roads cleared quickly except during a major storm, which can shut down travel for several days at a time. Posters consistently recommend monitoring forecasts roughly a week ahead and building real flexibility into a March itinerary. Posters generally rate March as a high-precipitation, snow-capable month, workable for a visit but requiring genuine weather-contingency planning.

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.
