Hanoi in November: 26°C / 79°F afternoons, 19°C / 66°F nights, rain on about 5 days, and a dry second half with about 14mm.
November is where Hanoi's dry season begins. NOAA NCEI's record for the city's WMO station 48820 puts the afternoon at 26°C / 79°F and the night at 18.8°C / 66°F, both about 3.4 degrees below October, with 57mm of rain on 4.7 days. Most of it falls early: the first half of the month collects about 44mm, the second about 14mm. Suede survives, a rain shell stops earning its space, and a corduroy overshirt covers the night. Early November still brings about 4 afternoons at 30°C, which keeps a short-sleeved shirt in the bag. Friday 20 November is Vietnamese Teachers' Day, and Tuesday 24 November is Vietnam Culture Day, a new paid public holiday.
October takes a third of the rain away. November takes most of what is left: after the middle of the month Hanoi collects about 14mm, and the first thing you pack for is a cool night.

Pack the layer October did without. On NOAA NCEI's record the average November night is 18.8°C / 66°F, 3.4 degrees below October's, and a rust corduroy overshirt with two flap pockets goes on over a shirt at dusk and hangs open until you are back at the hotel. Corduroy rather than wool, because the afternoon still reaches 26°C and you carry it for half the day.

Sleeves rolled at a 26.4°C lunch, sleeves down for dinner: one shirt covers both. A cream cotton button-down with a chest pocket sits under the rust overshirt without a clash and tucks into the wide chinos for a restaurant in the French Quarter. Buttoned at the cuff, it also covers your arms on the ride home as the air drops toward 19°C.

Early November still has about 4 afternoons at 30°C or more, and long sleeves are too much for them. A mid-khaki cotton-linen camp-collar shirt, worn untucked, moves air on a walk from Hoàn Kiếm Lake to Đồng Xuân Market and takes the overshirt on top once the sun sets, at about 5:15pm.

November's dry pavements are what make pale trousers possible. With rain on about 5 days, and about 14mm in the whole second half, cream wide-leg chinos stay clean through a day of walking. A wide leg moves air on a 26°C afternoon, and the pressed crease keeps them right for dinner.

Suede comes out in the driest stretch of the year. Rain on about 5 days leaves little that can mark brown suede, and a lug sole grips worn paving and temple steps. A rust-tan leather saddle ties the loafers to the overshirt and the scarf. Break them in before you fly, because these carry every walk of the trip.

You need somewhere to put the overshirt between noon and dusk, and this is it. A tan canvas messenger with brown leather straps and top handles takes a folded corduroy shirt, the scarf and a water bottle, worn across the body so your hands stay free in traffic. Canvas is a fair bet in a month with rain on about 5 days.

Wind it once for the ride home. An 18.8°C night feels colder on the back of a motorbike taxi, and a lightweight rust cotton scarf covers your neck without the weight of wool. By day it folds to nothing in the messenger, and it repeats the rust of the overshirt.

Wide chinos need a belt, and a braided one gives a little over a long day of walking and eating. Brown matches the suede loafers, so the capsule carries one leather colour, and the silver buckle is the only metal in a cream-and-rust outfit.
Khaki camp shirt, untucked · cream wide chinos · braided belt · brown suede loafers · canvas messenger with the overshirt folded inside. Phở before eight, Hoàn Kiếm Lake and the Old Quarter by nine, Đồng Xuân Market before the midday 26°C.
Cream button-down tucked in · rust corduroy overshirt open · same chinos, belt and loafers · rust scarf wound once. Sunset at about 5:15pm, dinner in the French Quarter, then a motorbike taxi back as the air drops toward 19°C.
A suggested look — rust corduroy overshirt, cream button-down shirt, cream wide-leg chinos, brown braided belt, brown suede penny loafers.
Per NOAA NCEI's global summary of the day for WMO station 48820, which NOAA files as Noi Bai International, November's average daily maximum is 26.4°C and the average minimum 18.8°C / 66°F across 1991 to 2020; the rounded afternoon is 26°C / 79°F. Rain averages 57mm on 4.7 days with at least 0.01in, from the 21 Novembers with daily rain reports, and the second half of the month averages about 14mm. About 6 days still reach 30°C, most before the 16th. Mean relative humidity is near 75%. Daylight shrinks from 11h 23m on the 1st to 10h 58m on the 30th.
A rust corduroy overshirt, a cream long-sleeve button-down, a khaki short-sleeve camp-collar shirt, cream wide-leg chinos, brown suede penny loafers, a tan canvas messenger bag, a light rust cotton scarf and a brown braided belt. That covers a 26°C / 79°F afternoon at the Temple of Literature, an 18.8°C / 66°F night on the way back from dinner, and the handful of early-November days that still reach 30°C. Leave the rain shell, the wool coat and the heavy knitwear at home.
Tuesday 24 November 2026. Viet Nam has made 24 November a paid public holiday, Vietnam Culture Day, and the government's news portal says entry fees at public cultural and sports venues are to be waived or reduced that day. How much leave will surround it had not been settled when this page was written, so check before you book. Four days earlier, Friday 20 November, is Vietnamese Teachers' Day, set by a 1982 Council of Ministers decision; the Ministry of Education and Training marked its 40th anniversary in 2022. For a museum day, wear the cream button-down with the sleeves rolled, the wide chinos, the belt and the suede loafers, and carry the overshirt in the messenger for the 18.8°C ride home.
Late November for dry weather, early November for warmth. On NOAA NCEI's record the first half of the month averages 27.6°C by day, 19.6°C at night and about 44mm of rain; the second half averages 25.3°C, 18.0°C and about 14mm. Afternoons at 30°C or more cluster early, about 4 before the 16th and 2 after. Pack the same capsule for either half, and move the camp shirt to the bottom of the bag late in the month. Late November also holds Teachers' Day on the 20th and Culture Day on the 24th, and it is when the rare early cold snap lands: the National Centre for Hydro-Meteorological Forecasting (NCHMF) issues a northeast monsoon bulletin, tin gió mùa đông bắc, when cold air is on its way, so check it before a day trip.
November is about 3.4 degrees cooler at both ends and roughly half as wet. From the same NOAA NCEI record, October averages 29.8°C by day and 22.2°C at night with 104mm on 7.6 days; November drops to 26.4°C and 18.8°C with 57mm on 4.7 days. Afternoons at 30°C or more fall from about 18 to about 6, and humidity eases from near 76% to near 75%. Our October guide packs a cotton cardigan for air-conditioning; November needs a real evening layer, and swaps canvas for suede now that the rain is mostly gone.
Short sleeves by day and long sleeves again after dark, with one pair of trousers under both. Dress for the 8-degree gap between a 26.4°C afternoon and an 18.8°C night rather than for either end of it: a layer you can carry, closed shoes for dry pavements, and one scarf light enough to live in a bag.
