中文介绍
中国幅员辽阔，同一时间去不同地方，天气天差地别：1 月的三亚 26°C、哈尔滨零下 10°C，7 月的北京 31°C、西宁 24°C。选出行时间，主要看三点：气温是否舒适、降水是否集中、人流是否拥挤。北方（北京、西安、敦煌、新疆）春秋最舒服，夏天干热、冬天干冷；南方（桂林、广州、成都）多雨湿热，秋冬更宜；云贵高原（昆明、丽江、大理）四季如春；海南三亚冬季温暖。
人流上，黄金周（五一、十一）与春节是绝对高峰，寒暑假也拥挤；想避开人流，选 4–5 月、9–10 月（除黄金周）或 11 月后。本工具给日均最高温、月降水和推荐月，帮助你快速锁定窗口。实际出行前，仍建议查临近天气预报与景点预约政策。

English
China is huge, and the same month can be wildly different across the country: in January, Sanya is 26°C while Harbin is minus 10°C; in July, Beijing hits 31°C while Xining stays at 24°C. Picking a travel time comes down to three things: comfortable temperature, low rainfall, and manageable crowds. The north (Beijing, Xi'an, Dunhuang, Xinjiang) is best in spring and autumn, dry-hot in summer and dry-cold in winter; the south (Guilin, Guangzhou, Chengdu) is rainy and humid, better in autumn and winter; the Yunnan plateau (Kunming, Lijiang, Dali) is spring-like all year; and Sanya on Hainan is warm through winter.
On crowds, the golden weeks (May Day, National Day) and Spring Festival are absolute peaks, and school holidays are busy too. To dodge the crowds, aim for April–May, September–October (outside the golden weeks), or after November. This tool gives the average daily high, monthly rainfall and recommended months to narrow your window. Before you go, still check the near-term forecast and any attraction booking rules.
