Tainan weather in November

Forum posters cite the Central Weather Bureau's average November temperature for Alishan around 10.3C, with colder days dropping to around 5C and a typical range in the back half of the month between 5-20C - genuinely unpredictable given the mountain elevation. Posters consistently rate November as a good time for Taiwan generally, outside typhoon season with comparatively little rain, though some visitors still reported 3-4 days of rain during a November trip, described as steady rather than heavy downpours. Posters consistently recommend a raincoat over an umbrella for ease of movement, and advise against shorts or skirts given how cool it runs at altitude. Posters generally rate November as a great, if cool, month for hiking and long walks around Alishan.

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.
