FAQs about flying to Hanoi

Hanoi climate

Hanoi’s climate is generally charcaterised by hot and humid summers and relatively cold and dry winters. During the dry season, October through April, Hanoi is cool, with temperatures on average between 16 and 25 degrees Celsius and the city is mostly dry. The rainy season runs from May to September and is hot, temperatures around the high 20s, with heavy rains.

Getting around Hanoi

Two feet are good; Hanoi is compact. And if you need to cross the street do so very slowly, making eye contact with the drivers. Two wheels are good too. The traffic might look scary, but get into it and wheel around like the Vietnamese do. If you want to be driven around, there are lots of options. Motorcycle taxi rides – Xe om – are offered almost everywhere. Air-conditioned taxis are more comfortable, and still cheap.

For the tourist experience take a xich lo, the red-covered rickshaws. And tip the driver…
