Vejret i Xiamen i september

Forum posters describe rain building through May along China's southeast coast, including Xiamen, with conditions worsening further into June when thunderstorms become common. Posters consistently recommend the second week of May specifically, avoiding both the May 1st national holiday crowds and, ideally, some of the month's rain, while acknowledging there's no guarantee of dry weather even then. Posters note April can also bring real rain, so May isn't necessarily worse than the month before it. Posters generally recommend staying around Zhongshan Road in Xiamen's old town for the most authentic local food and atmosphere regardless of exact travel dates. Posters generally rate May as a workable but increasingly wet month to visit Xiamen, with the first half of the month a better bet than the back half.

Forum posters describe Xiamen's weather as genuinely pleasant even heading into the cooler months, with one comparison likening its winter conditions to a Tampa, Florida winter - well above freezing, generally comfortable, and with notably good air quality for a Chinese coastal city. Occasional cold fronts can push temperatures down by 5C or more for a few days at a stretch before things return to the milder baseline, so posters recommend packing a layer for those cooler snaps even though the overall month reads as mild. As a subtropical coastal city, Xiamen is repeatedly named among the more livable, walkable options on China's southern coast for travelers looking to avoid the harsher winters further north or inland.
