I - Is there a Vietnam rainy season in the north?
In fact, the northern part of Vietnam is located at a higher latitude than the southern, so it is sharply influenced by the northeast monsoon. Characterized by humid subtropical climate, this region has 4 seasons of which the winter is cold and the summer is hot, the autumn is cool and the spring is warm. There is no specific rainy season in the north. The rains are scattered and change in frequency and nature according to different seasons.
1 - Summer rain - the beginning of the north Vietnam rainy season
Summer (May to August) in the North of Vietnam is hot and sultry, sometimes the temperature can rise up to 42oC. The heat causes the water in the rivers and the soil to vaporize quickly, therefore, pouring rains frequently occur, especially in the late afternoon. The characteristics of the rainy season in vietnam in the north are sudden, torrential, quickly come, quickly go. The signal is thousands of masses of dark clouds covering the sky, thunder rumbling, wind howling. The rains often accompany thunder and lightning. The remarkable amount of Vietnam rainfall (approximately 400 - 800mm on average) is necessary for agriculture.

Traveling during the Vietnam rainy season in the north, you should consider having a holiday at beaches such as Ha Long bay, Cat Ba island or in places with abundant trees like national parks of Cat Ba, Cuc Phuong or Pu Luong wildlife reserve.
July and August are the peak of the rainy season in Vietnam’s northern provinces, the sunlight is less intense but there is a likelihood of tropical storms because this has been long known as the storm season in the North. Hence, beaches and marine tourism are no longer advisable.

At the end of the rainy season in Vietnam in autumn, the best places for visiting are the yellow rice terraced fields in the north, of which Hoang Su Phi (Ha Giang province) or Mu Cang Chai district (Yen Bai province) are highly recommended. Besides, experiential tourism in Sapa (Lao Cai province) or Ba Be lake (Bac Kan province) is not a bad idea.

The cold & dry of winter is best for trekking, climbing mountains in Ha Giang province and Sapa town (Lao Cai province). The nature at these mountainous places is so wild and majestic with a mist blanket covering around the neck of the rocks, which provokes the curiosity and sense of adventure of ambitious travelers. The cold of the weather is a great support since it reduces the speed of dehydration of your body.
