5月のAltaについての旅行者の声

近くのソルトレイクシティからのメモ(29 km)

Altaには5月のメモがまだありません — これは季節を共にする近くのソルトレイクシティについてのメモです。

May in Salt Lake City is two months in one, and the local saying regulars quote is that if you do not like the weather you should wait a minute. Early May is the unpredictable half, with snow still possible at higher elevations; late May settles into mild to warm, their range running from 60 to 90F against our row's 23C average high. The advice is layers, because the swing from the morning low to the afternoon high is large and grows larger the higher you drive. That elevation is the other May warning: snow and mud can still be sitting on the upper trails, so the hiking you planned may have to wait for the melt. Our row keeps 0.5cm of snow inside the May normal. The record: 10C nights, 3.6 precipitation days carrying 31.5mm and 12.5 hours of sun.

Altaのほかの月

Alta-forum threads on a September visit describe lift-served hiking access to Albion Basin as genuinely ending right around the start of the month, posters naming a season that typically runs from late June through the first few days of September. Regulars call Cecret Lake, Red and White Pine, Catherine's Pass and Grizzly Gulch real standard trails around Alta, several posters naming these the go-to routes in Little Cottonwood Canyon. Posters call fall color genuinely starting the last week of September into early October, several regulars naming this a reason to time a trip toward the later part of the month. Regulars call September mornings genuinely cool even with warm afternoons, several threads recommending layers for early hikes. Posters recommend checking lift and parking access before planning around Albion Basin, several regulars calling this standard given how the cutoff shifts year to year. The record: 17C days, 7.8C nights, 96.7mm across 12 days and 52 percent humidity.

Alta-forum threads on a November visit describe opening day as genuinely conditions-dependent, posters naming a typical window around November eighteenth to twenty-first though timing shifts with how much snow has fallen by then. Regulars call Alta's higher elevation and heavier natural snowfall a real advantage, several posters naming this why early-season conditions here hold up better than at nearby Utah resorts. Posters call a confirmed opening date genuinely unreliable to plan around, several regulars recommending flexible travel dates for a November trip. Regulars call early-season terrain considerably more limited than full winter, several threads warning only some runs are typically open right after opening day. Posters recommend checking daily snow reports before finalizing plans, several regulars calling this standard given how much conditions shift early in the season. The record: 1.4C days, -6.3C nights, 73mm across nearly 9 days and 66 percent humidity.

Alta-forum threads on a July visit describe Albion Basin as genuinely at peak wildflower bloom, posters naming the seasonal gate opening July first as the real signal hiking there is finally possible. Regulars call the Cecret Lake trail a real standard pick, several posters naming it an easy, family-friendly way to reach the wildflower meadows. Posters call parking genuinely limited once the gate opens, several regulars recommending an early start or the shuttle to avoid a long wait at the trailhead. Regulars call July mornings comfortably cool before afternoon warmth sets in, several threads naming this the real window for a comfortable hike. Posters recommend checking bloom reports before a July trip, several regulars calling timing genuinely variable year to year depending on the past winter's runoff. The record: 22.8C days, 13.4C nights, 86.4mm across nearly 14 days and 44 percent humidity.

Alta-forum threads on an October visit describe this as genuinely off-season for skiing, posters calling the resort typically not opening lifts until around November eighteenth, conditions permitting, well after most October trips. Regulars call fall colors a real reason to visit anyway, several posters naming late September into early October a beautiful, genuinely lonely window for canyon scenery. Posters call weather risk genuinely rising as October goes on, several regulars warning an early system is possible even before the resort itself is ready to open. Regulars call this a real quiet stretch between summer hiking season and the winter rush, several threads describing October as neither one thing nor the other. Posters recommend treating an October trip as a scenery visit rather than a ski trip, several regulars calling this the honest expectation. The record: 7.7C days, -0.8C nights, an extraordinarily high 75.3mm across over 8 days and 58 percent humidity.
