Climate & Weather in Vietnam

Vietnam is spread across three very different climate zones leading to three very different distinct weather patterns depending on which area of Vietnam that you are considering on visiting. Due to this fact, if you plan to tour the entire country it is advised to bring several items that you can layer so that you are dressed appropriately for each region as you travel.

In the Northern areas Vietnam experiences the normal four seasons, all of which are quite temperate in nature. During the winter months temperatures can drop as low as 15°C in Northern peaks such as Hanoi, while the summer months offer high temperatures and very little precipitation.

During the spring months which fall between March and April the weather is mild and still dry as well as during the autumn months of October to December. It is imperative to note that in the Highlands area summer and winter climate tends to be on the extreme side so be prepared for cold winters and high smouldering temps in the summer.

On the other hand, in the Southern areas of Vietnam there are only three seasons: the hot season, which lasts from March until the end of June, the rainy season which stretches from July through November, and the cooler season, which lasts from December until February, although it does tend to stay quite dry.

The hottest month in the southern regions is April when temps can reach 33°C. The rainy season is the worst time to plan a visit as temps can get very hot and rain occurs almost every day causing mosquitoes to come out by the dozens. For this reason December to February is the best time to plan a visit to the south with cooler evenings and a low amount of precipitation.

The Central region has perhaps the easiest climate to understand since there are only two major seasons, the hot and the cold season. During September the area does experience monsoon conditions, which continue on through February along with heavy winds, rain, and sea swells. It is best to avoid this time of the year if you want to visit Central Vietnam. While the global climate is changing slightly every year, the extremes of weather in Vietnam are simply getting more extreme, so it is best to avoid monsoon season and the rainy seasons.
