What to Wear in Taipei in October
Taipei in October: 28°C / 82°F afternoons, 22°C / 72°F nights, 150mm across about 13 wet days — half of September's rain, and still no coat.
- Pale-blue packable rain shell — 150mm still falls, across about 13 days
- Sage cotton-linen tee — 74.3% humidity and 3.8 hours of sun dry nothing thick
- Navy drawstring wide-leg trousers — hem clear of standing water, splash reads as texture
- Grey mesh runners — closed for night-market concrete, dry by morning
- Folding umbrella in the bag — every 7-Eleven sells one for about NT$200
- One thin overshirt — MRT cars run near 18°C / 64°F against a 28°C / 82°F street
- Knitwear past one thin layer — nights hold at 22.4°C and it never comes out
- Suede or canvas — about 13 wet days at 74.3% humidity, with no drying window
- A fixed outdoor itinerary for the first half — October is the typhoon tail
- An autumn wardrobe because the calendar says October — Taipei has not turned
October is the month Taipei's rain halves and its heat breaks, and neither one leaves. Central Weather Administration (CWA) normals give the afternoon 28°C / 82°F over a 22°C / 72°F night, 150mm across about 13 days against September's 315mm, 117.6 hours of sun (under four a day) and 74.3% humidity, so nothing soaked in the morning dries by evening. Pack for drying rather than for warmth — no coat goes in this bag, and one thin overshirt covers the MRT. The month turns on 10 October, National Day, when Zhongzheng closes around the Presidential Office and the fireworks run after dark.
September gives Taipei 315mm of rain. October gives 150. That is the whole change, and it is not enough to put a coat in the bag.
The capsule
01Pale-blue packable rain shell, hoodedStart here, because about 13 days of the month decide what the other eighteen can be. A hooded shell with a drawcord hood, a chest zip pocket and a drop hem keeps the rain off a tee that would otherwise stay damp until tomorrow, and it packs down small enough to live in the crossbody between showers. Pale blue rather than black, since the sun comes back out at 28°C / 82°F and a dark shell turns into a sauna.
02Sage cotton-linen tee, short sleeveYour default top for the whole month, and the reason the bag holds two of them. Slub cotton-linen moves air in a way a poly knit does not, and at 74.3% humidity that decides whether a shirt is wearable again at four in the afternoon. Sage also hides the splash of a Raohe pepper-bun queue, which white shows within the first hour.
03White short-sleeve linen button-down, boxySwap this in when the day ends at a table rather than a stall. A boxy white linen button-down with turned-back cuffs and a curved shirttail hem carries a 7 pm dinner in Da'an where a tee reads as underdressed, then goes back out to Ningxia at ten without changing. Short sleeve, because long linen sticks to your forearms on a 22°C / 72°F platform at this humidity.
04Navy drawstring wide-leg trousers, croppedWide, cropped and elasticated at the waist, so the hem clears standing water and the leg moves air on a 28°C / 82°F afternoon. Navy earns its slot on the wet days: splash off a Zhongshan pavement reads as texture on navy and as a stain on stone or cream. No fly and no belt loops, which is what you want after a night-market dinner.
05Grey quick-dry mesh runnersClosed, breathable, dry by morning: that is the whole specification. An October day here is wet night-market concrete at Raohe and then damp granite steps up Xiangshan, and an engineered-mesh runner drains and dries where suede and canvas hold water through a 74.3%-humidity night. Grey, because white trainers finish after a single wet day in a market aisle.
06Navy coated-canvas zip crossbodyZip-top and worn across the body, which leaves both hands free for an EasyCard and an umbrella. Coated canvas or matte nylon rather than leather, since 74.3% humidity is what grows mould on an unsealed strap inside a week — the reason Taipei's own months say skip leather. Small enough to sit under the shell rather than over it, and deep enough for a folded umbrella that is still wet.
07Navy compact folding umbrellaFolding, never full-length. Rain arrives in Taipei with about fifteen minutes of warning on roughly 13 days of the month, and a long umbrella is unmanageable in a Ningxia aisle two people wide or on a rush-hour Bannan line carriage. Forget it and you lose nothing: every 7-Eleven and FamilyMart keeps folding umbrellas by the till for around NT$200.
08Pale-blue linen-cotton overshirtOne layer, and it is not for the weather outside. MRT cars, the Xinyi malls and every convenience store run near 18°C / 64°F against a 28°C / 82°F street, and an oversized linen-cotton overshirt goes on at the turnstile and off at the exit. Linen over knit on purpose: a sweater holds damp at this humidity and never dries, and a 22°C / 72°F night gives it nothing to do.
Day to night
Sage tee · navy drawstring trousers · grey mesh runners · shell folded in the bag · navy crossbody · folding umbrella. Coffee in Da'an at eight, Longshan Temple by nine, Dadaocheng before the afternoon cloud builds.
White linen button-down · same trousers and runners · overshirt on for the MRT. Xiangshan trailhead at six for Taipei 101 as the lights come up, then Raohe at nine with the shell still in the bag.
A suggested look — sage crewneck tee, navy cropped wide-leg trousers, grey mesh runners, navy zip crossbody, pale blue rain shell.
What to avoid
- Knitwear beyond one thin layer — nights hold at 22.4°C and it stays in the case
- Suede or canvas — about 13 wet days, 74.3% humidity, 117.6 hours of sun all month
- A long umbrella — unusable in a Ningxia aisle; NT$200 folding ones sit by every 7-Eleven till
- A fixed outdoor plan for the first half — October is the tail of typhoon season
- Packing an autumn wardrobe — the calendar turns, Taipei does not
Frequently asked questions
Per Central Weather Administration (CWA) monthly means for the Taipei station: the average daily maximum is 27.6°C / 82°F, the average minimum 22.4°C / 72°F and the monthly mean 24.6°C. Rain averages 150.2mm across 12.7 days. Read that day count carefully — CWA counts a precipitation day at 0.1mm or more, a lower bar than the 1mm threshold Japan's JMA applies, so Taipei's wet-day figures run higher than a Japanese city's for the same rain. Sunshine totals 117.6 hours, about 3.8 a day, and relative humidity averages 74.3%.
Yes, and for most visitors it is the best month of the year. Rain drops from September's 315.2mm to 150.2mm and the afternoon falls from 31.5°C to 27.6°C, which is what makes the night markets and the Xiangshan steps comfortable again after dark. Two things to plan around. October sits at the tail of the typhoon season, so a system can still cross Taiwan in the first half of the month; and 10 October is National Day, when the ceremony closes streets around the Presidential Office in Zhongzheng and hotels price the weekend accordingly.
A pale-blue packable rain shell, a sage cotton-linen tee, a white short-sleeve linen button-down, navy drawstring wide-leg trousers, grey quick-dry mesh runners, a navy coated-canvas zip crossbody, a compact folding umbrella, and one thin linen-cotton overshirt for air-conditioning. Leave the knitwear, the suede, the canvas and the coat at home. Every item answers one of two questions: does it breathe at 74.3% humidity, and is it dry by morning.
Not a warm one. Nights bottom out at 22.4°C on CWA normals, which is a T-shirt temperature, so a coat or a wool jacket stays in the suitcase for the entire trip. What you do need is a rain layer: a packable hooded shell for the roughly 13 days that carry rain, pulled on over the same clothes you wore at two in the afternoon. Indoors is the other case — MRT cars and the Xinyi malls run near 18°C / 64°F, and a thin overshirt covers that without a sweater's bulk.
October is the month September keeps promising. CWA puts September at 31.5°C by day and 25.0°C at night with 315.2mm of rain across 13.4 days; October drops to 27.6°C and 22.4°C with 150.2mm across 12.7 days. The wet-day count barely moves, and humidity actually rises slightly, from 73.8% to 74.3% — what halves is the volume, because September's rain comes in typhoon bands and October's in northeast-monsoon drizzle. September is the wettest month of Taipei's autumn; October is the first one you can walk through.
Summer clothes with one layer added. Walk Da'an in the middle of the month and the street is short sleeves, cropped wide trousers or a midi skirt, flat closed shoes, and a thin overshirt or cardigan carried for the MRT rather than worn. Zhongshan runs a shade smarter, a collared shirt instead of a tee and a structured bag instead of a canvas one, but the silhouette is the same and nobody is in a coat. The tell that marks a visitor is knitwear: a sweater at 27.6°C / 82°F says you packed for the calendar rather than for the city.

CWA counts a precipitation day at ≥0.1 mm, a lower threshold than the ≥1 mm used by JMA, so Taipei's wet-day counts run higher than Japan's for the same rain.
