5月的博尔德旅人笔记
来自附近丹佛的笔记（相距 39 公里）
博尔德还没有自己在5月的笔记——下面这些是关于丹佛的，离得够近，季节相同。
Denver-forum threads on May draw a sharp elevation line: the city itself is warming fast by this point, while the resort towns up in the mountains - Vail, Aspen, Breckenridge - are stuck in what regulars call mud season, the snow melting away without the ground being dry enough yet for summer trails. Anyone chasing actual snow is told to just drive a high mountain pass instead; above roughly 9,500 feet there's still plenty of it through mid-May, less likely after the 22nd as the month wears on. Down in Denver proper the record backs the warming trend: 22.2C days, 7C nights, 74mm of rain across eight days, 11.6 hours of sun, and a late 4.4cm of snowfall still possible early in the month before the city's own spring properly arrives.

Forum posters describe March as Boulder's snowiest month on average, yet genuinely fickle - a 70F sunny day can be followed by two feet of snow the next. Posters are consistent that early March still sees bars, breweries, restaurants and music venues running in full swing regardless of weather. Posters recommend traction devices for hiking boots given the mix of clear and icy trail conditions, noting that Boulder's foothill trails typically stay open if there hasn't been a recent storm, while higher mountain trails often remain snowbound well into the month. Posters are direct that a storm disrupting travel plans is a real possibility that's impossible to predict far in advance, making a last-minute forecast check worthwhile. Posters generally rate March as genuinely unpredictable but workable for a Boulder visit, hiking gear and flexible plans the key preparation.
Forum posters describe September as sunny, mild and generally beautiful, typically 70sF by day and 50sF at night in the Boulder/Denver area - though they're candid it can occasionally swing from warm and sunny to unexpectedly cold with snow. Early September (before Labor Day and before fall color/elk rut kicks in around September 21) gets flagged as a genuine lull in visitation, with quieter trails and close-to-ideal hiking temperatures with a lower chance of afternoon thunderstorms. Visiting closer to late September trades that quiet for peak fall color and the elk rut in nearby Rocky Mountain National Park - one of the most popular windows of the year there.
