ガトリンバーグ 9月の天気

Great Smoky Mountains-forum threads on September conditions describe early-month days as still genuinely warm at lower elevations, upper seventies to low eighties Fahrenheit around Gatlinburg with cooler readings up at higher stops along the ridge. Posters call humidity a real factor, staying high enough that nights don't cool off as sharply as daytime intensity might suggest. Regulars describe September as one of the drier months on average, though posters are consistent this varies year to year. Posters call late September a genuine turning point, temperatures easing toward the mid seventies and crowds noticeably thinner once summer visitors clear out. Regulars recommend checking elevation-specific conditions rather than a single valley forecast. Posters call the ridgeline overlooks worth the trip regardless of conditions. The record: 22.6C days feeling like 23C, 13.6C nights, an extraordinarily high 146mm across 9 days and 78 percent humidity.

Forum posters cite typical November days in Gatlinburg in the low-to-mid 60sF with evenings dropping into the 40s or even high 30s, describing conditions as pleasant by day and genuinely cool at night. Posters are consistent that November is too early for snow at valley level, calling any snow before Thanksgiving a rare fluke rather than a realistic expectation. Posters describe some fall color still lingering into mid-November in a typical year, though it varies and can already be mostly gone by then. Posters note crowds and accommodation rates both drop compared to October's peak leaf-season rush, with one major exception: the weekend after Thanksgiving ranks among the single busiest of the entire year, driven partly by the Christmas lights and Winterfest displays that go up around November 9th. Posters generally rate November as mild by day, cool by night and a good value window for Gatlinburg outside the Thanksgiving-weekend crowd surge.

Forum posters put typical May highs in the mid-to-upper 70sF with lows in the mid-to-lower 50sF, though some report highs into the 80s and lows near 60 by mid-May - shorts and t-shirts by midday, but pants and layers for the notably cooler mornings and evenings. Rain is normal but not usually heavy. The month is repeatedly called an excellent window: less humidity than summer, wildflowers in full bloom, and crowds that stay well below the Memorial Day surge since school is still in session - weekday visits in particular are described as notably quieter than weekends.
