Vietnam Weather and Climate

Because of its geography, the climate in Vietnam varies greatly from north to south. Tropical monsoons occur from October to April in the north and south and from May to September in the centre, this is when most of the country's rain falls. It is almost totally dry throughout the rest of the year. It can get exceptionally hot, however, all year round, but the north has a cooler time between October and April. It is best to travel between the shifting of seasons. Temperatures around the country often reach 40C in the height of the hot and rainy season (May to September), but the northern highlands and Hanoi can often seem chilly in the winter. 

Loose, natural fabrics all year, but warmer clothing is required in the highlands, and in the winter in north Vietnam. Rainwear is essential during the wet season.
