9月的大理市旅人笔记
来自附近丽江市的笔记（相距 143 公里）
大理市还没有自己在9月的笔记——下面这些是关于丽江市的，离得够近，季节相同。
Lijiang-forum threads comparing late August and September call early September marginally better than late August, posters describing late September as better again given the lower chance of showers by that point. Regulars call late-September conditions typically mild by day with low cloud and a real chill setting in overnight. Posters recommend avoiding China's National Day holiday week, October first through the seventh, several regulars calling that stretch genuinely crowded, expensive and best avoided by visiting just before or after. Regulars call the old town and surrounding Yunnan scenery worth building extra time around, September considered a strong month for combining Lijiang with wider regional stops. Posters recommend real layers for the evening chill despite comfortable daytime conditions, elevation here making a genuine difference after dark. The record: 22.5C days feeling like 22C, 14C nights, an extraordinarily high 260.9mm across over 25 days and 76 percent humidity.
大理市的其他月份
Yunnan forum posters generally rate October as a pleasant month for Dali - sunny and warm by day, with a light jacket needed once the sun drops in the evening. Early October can still run a bit cool and cloudy with occasional rain, a holdover from the tail end of the wet season, so several posters suggested mid-to-late October both for milder weather and to skip the crowds and high prices of China's National Day holiday week. Overall it's considered comfortable layering weather rather than either extreme.
Forum posters describe April across Yunnan (Dali included) as one of the better months overall, though genuinely cold mornings and evenings persist alongside comfortable daytime warmth - temperature swings of roughly 8-18C within a single day are commonly cited, with winter-weight layers, gloves and a cap recommended for early/late hours even as daytime sportswear or a light jacket suffices. Posters name June through September as the region's rainy season, meaning April sits comfortably in the drier part of the year, with early May and late September named as similarly favorable low-rain windows. Posters note Yunnan's elevation varies significantly city to city, so conditions can shift meaningfully even within the same itinerary depending on altitude.
