Best time to go to Hanoi
Hanoi is Vietnam's fascinating, layered capital — a city of ancient temples, French colonial architecture, chaotic street life and extraordinary food that rewards travellers who take the time to explore beyond the obvious. October to December is a particularly lovely time to visit the city— temperatures are mild and pleasant (20-25°C), humidity is manageable and the city is at its most animated. January to March can be cool and occasionally misty (Hanoi does experience a cool, damp season), while May to September brings serious heat and humidity alongside the risk of heavy rain.
TL;DR
When is the best time to visit Hanoi?
For Australians visiting Hanoi, the best time to go is from October to December, when the weather is at its most comfortable. It’s a bit cool at night, but very comfortable for sightseeing during the day.
Weather in Hanoi
Hanoi has a distinct four-season climate unlike most of Vietnam. From October to December, temperatures are mild and dry — genuinely comfortable for sightseeing, cycling the Old Quarter and day trips to Halong Bay.
January and February can be cool (15-20°C) and drizzly, while March and April warm up pleasantly before the heat arrives. May to September is the hot and humid season, with temperatures regularly hitting 35°C, very high humidity and significant rainfall in July and August — not impossible to visit, but considerably less comfortable. The peak of comfort for Australian visitors is October to November and then again in March and April.
Prices in Hanoi
Hanoi is one of Southeast Asia's most affordable city destinations for Australian travellers, with budget and mid-range accommodation very competitive. Prices rise during peak tourist season (October to April) and significantly during the Vietnamese New Year (Tet, which falls in January or February) — accommodation books out and prices spike around Tet.
Christmas and New Year are also busy periods with Australian holiday makers. The most affordable time to visit is during the hot and wet May to September period, when tourist numbers drop, hotels discount heavily and flights can be cheaper. Shoulder periods of late September to October offer improving conditions at still-reasonable prices.
Crowds in Hanoi
Hanoi's Old Quarter and key sites like Hoan Kiem Lake, the Temple of Literature and Ho Chi Minh Mausoleum are busy year-round, but peak season (October to April) brings the most international visitors. Tet (Vietnamese New Year) is a fascinating but complex time — many restaurants and businesses close, locals travel home to family and the city has an unusual quiet followed by a festive atmosphere.
Chinese New Year tourists add to numbers in this period. The slowest months for international tourism are June to August — hot and humid but cheaper and somewhat quieter. Weekday visits to the key attractions are always less crowded than weekends.

Travelling to Hanoi in each season
Hanoi's distinct seasons make timing genuinely important. Here's what to expect throughout the year.
Spring
When is it? March to May
Spring in Hanoi (March to May) sees warming temperatures and the occasional fine mist giving way to clearer days. It's a pleasant time to visit — the city is alive, Halong Bay day trips are good and the temperatures are comfortable before summer heat arrives. May can get quite hot and marks the edge of comfortable visiting weather.
Summer
When is it? June to August
Summer (June to August) is Hanoi's hot and wet season — temperatures hit 35°C and humidity is extreme. Afternoon downpours are common. It's less comfortable for sightseeing, but prices are lower and the city is less crowded with tourists. Typhoons can occasionally affect the north. Not the recommended time for most Australian visitors.
Autumn
When is it? September to November
Autumn (September to November) is one of the best times to visit Hanoi. The rains ease from September, temperatures moderate and by October the city is at its most comfortable and visually beautiful. The food scene is exceptional in autumn, and Halong Bay tours operate in good conditions. This is peak season, so book accommodation and tours ahead.
Winter
When is it? December to February
Winter (December to February) in Hanoi can be surprisingly cool and occasionally misty — temperatures can drop to around 15°C in January. Tet (January or February) is a fascinating cultural experience but requires careful planning. December is comfortable and festive. Pack a light layer for January evenings.
Overall, when is the best value time to visit Hanoi?
The best value time to visit Hanoi is in October or November. The weather is genuinely comfortable, the city is beautiful and prices — while not rock-bottom — are very reasonable by Southeast Asian standards. Alternatively, the shoulder period of late March to April offers warm, pleasant conditions before the heat sets in, at moderate pricing. If budget is the absolute priority, May or June sees the lowest accommodation prices and good flight deals, though you'll be trading comfort for savings. For most Australians, the October to December window represents the ideal balance of weather, experience quality and value — the extra you pay over the summer months is very much worth it.
