Het weer in Flagstaff in november

November is the hinge month on the Sedona forum: fair weather and the last of the colour early on, winter edging in by the end. Early November runs high 60s to low 70s F with chilly evenings; mid-month days stay pleasant and the nights get colder. The hiking argument is simple - this is the cool end of the year for it, with fewer people on the trails than the spring peak. Two timing notes regulars give: the crowds do not really thin until the second week, then Thanksgiving fills the town again; and the colour is mostly finished up-canyon by November, though West Fork can still be holding some. Snow is unlikely but not impossible - our row records 3.8cm across the month. The rest: 18.7C days, 3C nights, 2.7 precipitation days, humidity 47 percent.

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.
