台南市 5月の天気

Taiwan forum threads are direct that late May marks the start of the plum rain season, bringing rain on roughly half the days through the following weeks, with fog at Alishan described as an almost daily occurrence even outside heavy rain spells. The more typical pattern posters described was sunny mornings followed by afternoon thunderstorms lasting an hour or two before clearing again, rather than sustained all-day washouts. One specific frustration flagged repeatedly: the famous Alishan sunrise is genuinely hit-and-miss on foggy mornings, so visitors chasing it were advised to build in a backup morning if possible, and to always carry a proper rain jacket or poncho.

Forum posters describe July and August as Taiwan's hottest months, typically 33-36C with high humidity, and afternoon thundershowers a regular feature of the June-August stretch. Posters are consistent that August sits within typhoon season (June-October), with August, July and September the three months most likely to see a storm make landfall - roughly three to four typhoons affect Taiwan in an average season, and a direct hit during a trip can cost travelers one to two disrupted days. Posters are equally clear that summer travel remains genuinely popular despite the heat, pointing to Taiwan's excellent air-conditioned MRT, malls and convenience stores, plus shaved ice and bubble tea on seemingly every corner, as real relief options. Posters generally rate August as hot, humid and typhoon-season for Tainan, entirely workable with flexible plans and frequent air-conditioned breaks.

Forum posters describe February in southern Taiwan as cool and pleasant, typically 15-20C, milder than the 10-15C posters report further north - winter here is generally mild outside the high mountains. It's not officially the rainy season, but posters note rain remains a real possibility on any given day, so a light jacket that also handles rain is standard packing advice. Cold fronts can occasionally push temperatures down to around 6C for a couple of days, a real but temporary dip rather than the norm. Posters describe February overall as the tail end of winter with spring clearly approaching, milder than most visitors expect coming from more northerly climates.
