Ho Chi Minh City in January: 32°C / 90°F afternoons, 22°C / 72°F nights, 2 rain days and the coolest dawns of the year.
Pack for the driest, clearest weeks of the year. NOAA NCEI's record for Tân Sơn Nhất airport gives January 32°C / 90°F by day and 22°C / 72°F at night, with about 10mm of rain on 2 days, and its average low, 21.8°C, is the coolest of any month. In the airport's hourly reports it is about 22.5°C at 6am and 31°C at 3pm, and afternoon humidity averages 50%. Canvas and straw are safe again, and a linen shirt over a sundress covers the dawn. The month also runs toward Tết on Saturday 6 February; the Ministry of Home Affairs has proposed a public-sector break from Thursday 4 February, so plan errands for January.
January is the city at its most forgiving: dry pavements, a cool hour at dawn and afternoons at 50% humidity. It is also a countdown. Whatever you want made, bought or altered, do it before the first week of February.

Your dawn layer and your sun layer. At 6am the airport averages about 22.5°C, the coolest hour of the coolest month, and the shirt goes on over the sundress or buttoned over the white trousers; by nine it is 26.6°C and the sleeves roll up. Wide sky stripes on ecru linen hide a crease and pair with every other piece here.

White trousers were a gamble in October's storms; in January, with rain on about 2 days, they are safe. A flat-front straight leg cut at the ankle stays clear of the pavement, cotton twill holds its shape through a day of pre-Tết errands, and white under the striped shirt keeps the whole look to two colours.

For the afternoons, when the airport's humidity sits at 50% and a thin cotton bodice finally stops sticking. The wrap bodice and tiered skirt move air at 31°C, and the knee length is easy on a motorbike taxi. Keep the striped shirt over it until nine and for any temple, and wear it alone after that.

Sleeves and a midi hem for a pagoda or a family-style dinner, in linen that breathes at 50% afternoon humidity. The smocked waist gives it shape without a belt, and pale periwinkle sits between the sky-blue sundress and the white trousers, so the capsule stays in one family of blues.

Canvas is finally safe. With rain in no more than 3% of the airport's reports at any hour, a navy canvas slip-on on a jute sole stays dry all month, breathes at 32°C / 90°F, and goes from the white trousers to either dress. Navy grounds a pale capsule so it does not wash out in the midday glare.

At 10.8°N the noon sun still stands about 58° above the horizon in mid-January. A stiff boater keeps its brim level in a breeze, the flat crown sits well above the scalp so air moves, and a sky-blue band ties it to the shirt.

An open basket tote for a month of errands before the holiday. Tightly woven straw is light, takes the weight of a morning's shopping on two riveted leather handles, and is only a risk in rain, which January barely has. Carry it in the crook of your arm: the smooth leather handles won't snag the striped linen.

One piece of jewellery for the dinners of a dry month, when you can sit outside without a shell on the chair. Two short strands of cream pearls sit at the neckline of the sundress and inside the open collar of the striped shirt, and they weigh nothing in the tote.

A suggested look — sky blue tiered sundress, ecru and sky striped linen shirt, navy canvas espadrilles, pearl necklace.
Dry and at its coolest, which still means hot by afternoon. NOAA NCEI's global-summary-of-the-day record for Tân Sơn Nhất International Airport gives January an average high of 32.3°C (90°F) and a low of 21.8°C across 1991–2020, the lowest average low of any month; the hero rounds them to 32°C / 90°F and 22°C / 72°F. In the years with a complete rain record (1999–2012), January averages about 10mm on 2 days with at least 0.01 inch. The airport's hourly reports from 2006 to 2020 put it at about 22.5°C at 6am and 31.3°C at 3pm, with humidity averaging 71%, and 50% at 2pm. Sunrise comes late, about 6:11–6:16am, and sunset moves from 5:41pm to 5:56pm.
An ecru and sky-blue striped linen shirt, white cropped cotton trousers, a sky-blue tiered sundress, a periwinkle flutter-sleeve linen midi dress, navy canvas espadrilles, a straw boater, a straw basket tote and a pearl necklace. That covers a 22.5°C dawn, a 32°C / 90°F afternoon under a high sun and an evening outdoors at about 26°C. Leave rain gear, dark synthetics and anything that needs a hanger to breathe at home.
Tết, the Lunar New Year, falls on Saturday 6 February 2027. On 11 September 2026 the Ministry of Home Affairs submitted a seven-day break for public employees, from Thursday 4 February (the 28th day of the twelfth lunar month) to Wednesday 10 February (the 5th day of the first), and no decision had been published when this page was written. That makes the last two weeks of January the run-up, and the time for errands, fittings and gifts. Dress for long mornings on foot in dry heat: the striped linen shirt over white cropped trousers, espadrilles, the straw boater, and the straw tote for what you carry home.
Early January is a little cooler and drier; late January is the run-up to Tết. On NOAA NCEI's airport record, the first fifteen days average 32.1°C by day with about 2mm of rain, and the second sixteen 32.5°C with about 8mm, still on barely one day. Nights barely move (21.9°C, then 21.7°C). If you want the city at its most ordinary, come early; if you want to see it preparing for Tết, and can finish your errands before Thursday 4 February, come late.
February is hotter by day and even less humid. On the same NOAA NCEI airport record, February averages 33.4°C by day and 22.5°C at night against January's 32.3°C and 21.8°C, with about the same rain (9mm on 1 day against 10mm on 2). Average humidity falls again, from 71% to 67%, the lowest of the year, and to 46% at 2pm. Our February guide keeps the fabrics light, moves the palette to red, cream and marigold for Tết, and plans around the holiday week.
Pale colours and light fabrics, because January is the one month the weather stops forcing a choice. With rain on about 2 days and afternoon humidity at 50%, white trousers and canvas shoes survive the day, and a thin shirt over a dress covers a 22.5°C dawn. As Tết on Saturday 6 February approaches, the last weeks of the month are for errands, gifts and anything you want ready before the holiday week, so dress for long mornings on foot and keep one outfit for a dinner outdoors.
