Weather is various
Studying and understanding Vietnam's weather is one of the most important things to know before visiting the country. With such a large country, it's only natural that the weather in Vietnam varies greatly from region to region. When I was traveling around Vietnam, it was snowing in Sapa but I couldn't stand the heat in Mui Ne! Here's all you need to know about the weather in Vietnam, divided into three regions.
Northern Vietnam: In the north of Vietnam, the winter is bitterly cold, especially in areas bordering China, with temperatures dropping to single digits and even zero degrees Celsius. Summers are hot, and there are showers on occasion. Typhoons and storms frequently accompany the rainy season, causing landslides and other natural disasters.
So, between March and May, the best time to visit the north is right after summer and before the monsoons arrive. Or between October and November, immediately after the monsoon and before the start of summer (which can be tricky given the typhoons).
Central Vietnam: The weather in the central is tropical, with dry weather lasting from January to August and monsoons arriving in August and lasting until November, giving travelers a window from October to January to visit.
Southern Vietnam:As you travel south in Vietnam, the climate becomes more tropical, with two distinct seasons, the rainy and the dry, which are similar to those in central Vietnam, making it perfect for travel between December and April.
Typhoons in Vietnam: And going into Vietnam without being aware of them is a major risk. Although it is impossible to anticipate typhoons years in advance, most countries are aware of their impending approach and prepare appropriately. Check the weather forecast for typhoons online.
Typhoons are common in Central and South Vietnam between August and November, causing flooding, whereas typhoons arrive a little earlier in the north, around late June or July. Overall, October is a stormy month across the country, with typhoon season ending around December each year.
