Climate in Hanoi

The 'cay hoa sua' tree only flowers during autumn in Hanoi with a distinctive aroma
Spring brings the annual Tet holiday and this is when flowers are blooming and the city is at its most glorious. Locals of Hanoi believe that the light rain of this time bring good luck for the new lunar year and prosperity.
When summer comes along the heat and humidity become unbearable. Mosquitos come out in force along with other nasty insects so diseases such as malaria and dengue fever can become a serious problem. It is always wise to cover up (despite the searing heat!) and wear repellent, especially during the evening.
The autumn in Hanoi becomes much more tolerable with less moisture in the air and temperatures dropping to such a degree that jacket and jumpers are often sported by the Hanoians. Plus the indigenous species of ‘cay hoa sua’ tree only flowers at this time of year so and wondering the ancient streets is characterised by the scent of this distinctive aroma.
Winter is in fact quite brutal as there is a strange combination of cold and humidity. Many houses in this city don’t have any system of heating, making Hanoi appear colder than elsewhere in the country. It is wise to pack carefully and wear layers as the midday sun is still very fierce.
