Hanoi in February: 21°C / 70°F afternoons, 16°C / 61°F nights, drizzle logged on about 16 days, and Tết on Saturday 6 February 2027.
Pack for drizzle rather than rain. NOAA NCEI's record for Hanoi's WMO station 48820 puts the February afternoon at 21.5°C and the night at 15.8°C, rounding to 21°C / 70°F and 16°C / 61°F, with 25mm of rain on 8.8 measurable days. The daily summaries log rain or drizzle on about 16 days, and mean relative humidity passes 80%, so suede and canvas never dry between walks. The cold is easing: about 6 days a month still average below 15°C, most in the first fortnight. So bring a cotton overcoat, one warm knit, closed leather shoes and an umbrella. Tết, the Lunar New Year, falls on Saturday 6 February 2027.
February is when Hanoi's winter turns damp. The gauge collects 25mm; the daily reports log rain or drizzle on sixteen days. Pack for air you walk through, not rain you shelter from.

Wear it over everything on the drizzle days, about 16 of them on NOAA NCEI's record. A knee-length sand overcoat with a notch lapel and three buttons sheds fine drizzle, where wool stays damp at humidity near 81%, and it is light enough for a 21.5°C afternoon. Sand rather than black keeps the capsule in its cream family.

This is the warm layer for the first fortnight, when about 4 of the month's 6 cold days fall. A jade merino crew holds heat under the overcoat on a 15.8°C night and stays thin enough to sit under it without bulk. Merino rather than cotton, because it keeps its warmth in air above 80% humidity. Jade is the capsule's one strong colour against cream and red.

Pack one shirt for the holiday week. An ivory silk shirt with a point collar, balloon cuffs and a curved hem tucks into the cream trousers for a visit or a dinner, and takes the jade crew over it on a cold evening. Silk also dries faster than cotton on a hanger in a humid room.

Wide and pressed: the crease carries a holiday visit, and the width moves air on a 21.5°C afternoon. Cream survives a month of drizzle because the rain is too fine to splash, about 25mm across the whole month by the gauge. Wear them with the ivory shirt for the holiday and with the jade crew for everything else.

Closed, laced and wipeable. Drizzle on about 16 days at humidity near 81% marks suede and keeps canvas wet for days, while smooth black leather wipes dry at the door. A cap toe and a low stacked heel suit a holiday visit and still walk all day in the Old Quarter.

Most February rain is too fine for the gauge: 25mm on 8.8 measurable days, against rain or drizzle logged on about 16. It still soaks a coat by lunchtime. A compact red umbrella with a gold snap and a wrist loop folds into the bag between showers, and red is the capsule's accent colour.

The one piece of jewellery in the bag, for the holiday week. Two polished gold bangles give a cream-and-red outfit its gold and slide under the overcoat cuff on the street. Gold rather than silver ties them to the umbrella's snap and the bag's hardware.

Worn across the body with the flap closed, so the drizzle stays out. A black leather crossbody with gold hardware matches the derbies and holds a phone, cash and a folded umbrella. Leather wipes dry each evening, where a canvas bag stays damp for days in a month above 80% humidity.
Jade merino crew · cream wide-leg trousers · black derbies · sand overcoat · black crossbody · red umbrella. A drizzly morning: the Temple of Literature at nine, coffee indoors when the drizzle thickens, the Old Quarter by eleven.
Ivory silk shirt tucked into the cream trousers · jade crew over the shoulders · gold bangles · black derbies · sand overcoat open. Sunset at about 5:50pm, then a holiday dinner as the air falls toward 16°C. On the night of Friday 5 February, if Hanoi repeats its 2026 plan, the Giao thừa fireworks start at midnight and last 15 minutes: stand in the crowd at Thống Nhất Park with the overcoat buttoned against the drizzle.
A suggested look — sand overcoat, ivory silk shirt, jade merino sweater over the shoulders, cream wide-leg trousers, black derby shoes.
Per NOAA NCEI's global summary of the day for WMO station 48820, which NOAA files as Noi Bai International, February's average daily maximum is 21.5°C and the average minimum 15.8°C across 1991 to 2020, rounding to 21°C / 70°F and 16°C / 61°F. Rain totals 25mm on 8.8 days with at least 0.01in, from the 21 Februaries with daily rain reports, but the daily summaries log rain or drizzle on about 16 days and fog on about 3. Mean relative humidity is near 81%, and above 82% in the second half. About 6 days a month average below 15°C. Daylight grows from 11h 12m on the 1st to 11h 42m on the 28th.
A sand cotton overcoat, a jade merino crew, an ivory silk shirt, cream wide-leg pressed trousers, black leather cap-toe derbies, a red compact umbrella, two gold bangles and a black leather crossbody. That covers a 21°C / 70°F afternoon in drizzle, a 16°C / 61°F evening with the crew on, and the holiday week, when the silk shirt and the bangles come out. Leave the canvas shoes, the suede and the heavy parka at home.
Tết, the Lunar New Year, falls on Saturday 6 February 2027. Viet Nam's Ministry of Home Affairs has submitted a seven-day public-sector holiday from Thursday 4 to Wednesday 10 February; the Prime Minister's decision is pending, and private employers choose between set options. In 2026 Hanoi saw the year in with 15 minutes of fireworks from midnight at more than 30 sites, among them Thống Nhất Park, Hòa Bình Park and the Lạc Long Quân flower garden in Tây Hồ. The 2027 plan has not been announced; on that pattern the fireworks fall at midnight between Friday 5 and Saturday 6 February. Dress the week one step up: the ivory silk shirt in the cream trousers, the gold bangles and polished derbies, with the overcoat and red umbrella for the drizzle.
Early February for the holiday, late February for milder nights. On NOAA NCEI's record 1–15 February averages 21.1°C by day and 15.3°C at night, with about 4 days whose mean falls below 15°C; 16–28 February averages 21.9°C and 16.4°C, with about 2. The damp goes the other way: humidity climbs from near 79% to near 82%. The Ministry of Natural Resources and Environment's March–May 2025 outlook described March as bringing many days of light rain, drizzle (mưa phùn) and fog to the north, and on the same NOAA record March logs rain or drizzle on about 22 days, so late February is the start of that stretch.
February is warmer and damper. From the same NOAA NCEI record, January averages 20.1°C by day and 14.1°C at night; February 21.5°C and 15.8°C. Days with a mean below 15°C fall from about 10 to about 6, but days with rain or drizzle logged edge up from about 15 to about 16, and humidity rises from near 79% to near 81%. Our January guide is built on a wool coat and two knits. February swaps the coat for a cotton overcoat, keeps one knit, and keeps the leather shoes and the umbrella.
Light layers built for damp air rather than for cold. A February day at 21.5°C with drizzle on about half the days asks for a cotton overcoat over one knit, closed leather shoes, and an umbrella rather than a hood. For the holiday week, dress one notch up from what you would wear to walk the Old Quarter: pressed trousers and a silk shirt rather than a hoodie and jeans.
