Average monthly temperature and rainfall for Hanoi.
TEMPERATURE (°C)RAINFALL (mm)
In Vietnam, each region has its own microclimate. While the south is warm all year round, the north cools down in winter, with temperatures hovering between 15 and 20°C. Generally speaking, there are two main seasons – a wet summer between May to September and a dry winter from November to April. That said, it’s hardly a British winter – on the central and southern coast, temperatures rarely drop below the mid-20s, and clear skies and sunshine are the norm. The hottest months are March and April, when the mercury can top 40°C. This is accompanied by showers, although they tend to come in short, mid-afternoon downpours.
