Unlike the UK’s maritime climate where seasons often blur, Vietnam’s weather is sharply defined by monsoon patterns. In Hanoi, winter lows can drop to 10°C, while summer highs regularly exceed 35°C – a contrast that shapes everything from packing lists to flight choices.
What the live forecast reveals for Hanoi
The live forecast above gives you current conditions in Hanoi’s Old Quarter and surrounding districts. For a full picture of what to expect over the coming weeks, combine that snapshot with the seasonal averages below. Northern Vietnam experiences four distinct seasons, whereas Ho Chi Minh City and Da Nang follow a simpler wet–dry rhythm. For a deeper look at how this compares with Europe, see our 10-day forecast guide for the UK.
Vietnam weather by month – the Hanoi perspective
Hanoi’s climate is strongly seasonal, with a cool, dry winter from November to February and a hot, humid summer from May to August. Spring (March–April) and autumn (September–October) are transitional, often bringing the most comfortable conditions for sightseeing.
Winter (November – February)
Vietnam weather in November signals the start of the dry season. Daytime highs in Hanoi average 24–26°C, dropping to 17–19°C at night. Rainfall is low, and the city enjoys clear skies. By December, temperatures fall further: highs around 20–22°C, lows near 14°C. January is the coolest month, with average highs of 20°C and occasional chilly mornings below 10°C. For travellers used to UK winters, this feels mild but can require a light jacket. Vietnam weather in January is ideal for exploring Hanoi’s streets without the oppressive heat of summer. February remains dry but begins to warm slowly.
Spring (March – April)
March sees a gradual climb, with highs reaching 25°C. Weather Vietnam in April marks the first real heat of the year: average highs hit 30°C, humidity rises, and brief afternoon showers become more common. This is a popular month for visiting before the monsoon intensifies, but pack a light raincoat.
Summer (May – August)
From May onward, temperatures regularly exceed 33°C with high humidity. Rainfall peaks in July and August, often in short but heavy downpours. While the coast at Da Nang and the southern cities like Ho Chi Minh see similar humidity, Hanoi’s summer is also affected by occasional typhoon remnants that can disrupt travel plans. Check the UK weather warnings page (though it covers Britain, the principle of staying alert to official alerts applies when abroad).
Autumn (September – October)
September still carries summer heat – weather in Vietnam in September sees highs of 31–32°C and significant rainfall. By October, conditions improve: temperatures drop to a comfortable 27–29°C, and the rain eases. Vietnam weather in October is often cited as one of the best months for Hanoi, with crisp air and clear skies.
Best time to visit Hanoi
The most pleasant months are October to December and March to April. For a balance of dry weather and moderate heat, November and December are hard to beat – though January can be chilly, it offers the least rain. If you prefer warmer swimming conditions, the Gulf of Tonkin sea temperatures are highest in June and July (around 29°C). For a broader understanding of how other destinations compare, our Dubai weather guide shows a very different arid climate.
What to pack
- November to February: Light layers, a warm jacket for evenings, and comfortable walking shoes. An umbrella is rarely needed but handy.
- March to April: Lightweight clothing, a rain jacket or small umbrella for afternoon showers, and sun protection.
- May to September: Breathable fabrics, a raincoat or poncho, insect repellent, and a sun hat. Sandals that can handle wet streets are useful.
- October: A mix of light long-sleeve shirts for daytime and a thin jumper for cooler evenings.
Regardless of season, the Vietnam weather year round means you’ll need sunscreen and a reusable water bottle. For precise weekly conditions, refer to the live forecast above and the UK weather hub (which offers similar data tools for your home planning).

Does it rain much in December?

Can I get a reliable 14-day forecast for Hanoi?
Long-range forecasts for northern Vietnam are less precise than short-term ones due to monsoon variability. The live forecast above provides the most reliable 7-day view. For a 14-day outlook, check official sources like the Met Office or local Vietnamese meteorological services, but treat predictions beyond a week as general trends.
