Hanoi Weather in January & First-Timers' Travel Tips 2025

January is in the middle of Vietnam's dry season and peak travel season. If you're wondering whether it's a good time to visit Hanoi, the answer is yes as long as you're prepared for cool weather, cultural buzz, and some festival-related crowds.

This guide covers everything you need to know about Hanoi weather in January, including how it compares to nearby destinations like Halong Bay and Sapa, and what to pack.

What's the Weather Like in Hanoi in January?

January in Hanoi is cool and dry. Traveling this month, you can expect:

• Average lows to highs: 14°C–24°C (57–75°F)
• Rainfall: 20–30 mm (0.8–1.2 in)
• Humidity: Around 70%
• Sunshine: Limited, with frequent cloud cover or light fog

This is one of the driest months of the year, with only 1–2 days of light rain. If you've ever experienced a mild winter day in California's coastal cities like San Francisco or Los Angeles, Hanoi's January feels somewhat similar. It's great for city walks around Hoan Kiem Lake, exploring colonial alleys near St. Joseph's Cathedral, or outdoor food adventures in the Old Quarter.

However, mornings and evenings can feel quite chilly, so warm layers are a must. An indoor water puppet show is perfect for a warm night out.

And if you're hoping for clear, bright travel photos, you may be disappointed. Hanoi is often overcast or misty in January, with a gray, moody feel similar to winter days in London.

Is January a Busy Time to Visit Hanoi?

Yes, January is one of the busiest travel months in Hanoi thanks to New Year celebrations and the lead-up to Tet (Vietnamese Lunar New Year).

As Tet approaches (usually late Jan or early Feb), the city transforms: colorful flower markets in Hang Luoc Street, temples like Tran Quoc Pagoda fill with worshippers, and the lively Tet Market. It's festive and fascinating, but also hectic.

Expect crowds at spots like the Old Quarter and Ho Chi Minh Mausoleum, plus higher hotel prices and packed domestic flights, especially mid-to-late month. For a January trip to Hanoi, walk-ins are not suggested.

During the first three days of Tet, many shops and restaurants may shorten opening hours or even close (especially family-run ones).

With all this in mind, January can be busy and lively. If you're looking for a festive, cultural experience, it's worth the crowds. But if you prefer quiet sightseeing, an early January or post-Tet trip may be better. (See the Best Time to Visit Hanoi & more planning tips.)

What to Pack for Hanoi in January

Packing smart will make your Hanoi experience much smoother:

• Light sweater or fleece jacket
• Long pants and covered shoes
• Umbrella or light waterproof layer (optional)
• Pollution mask (air quality can vary, especially near busy roads)

If you're heading to higher elevations like Sapa, be prepared for much colder conditions — bring thermal layers and a heavier coat.

What's the Weather Like Near Hanoi in January?
