The summer lasts from May to August every year, it is very hot at this time and the normal temperature is around 30°C - 38°C, so that beach vacations are meant for children during this period. Although it is the high season for the domestics who travel by the short time in the summer in Vietnam, the mountainous areas or a lot of historical monuments are not too touristy since summer vacation for Vietnamese families normally means beach trips.

75% humidity on average and the precipitation level between 240mm and 340mm in recent years means you can get caught in the rain no matter what part of the month you plan your visit. Nonetheless, rains come and go quickly, and no matter how torrential they may get. The rain does some good in taking away all the heat and gives you a pleasant evening to hang out. Sometimes, there are some early storms in late August, but it’s really unusual. The storm season normally begins in September so summer is also very ideal for any foreign tourist who books and enjoys the trip to Vietnam.

Autumn is considered to be the most romantic time in Hanoi when you can enjoy a lot of specialities like green young rice (Cốm), dracontomelon (edible fruit named Sấu), milk flower (Hoa Sua), etc. Likewise, the North highland areas immerse in yellow grain, which offers spectacular scenes to catch sights of the endless yellow rice terraces — something you might have never seen before — and get in touch with ethnic minorities living in villages of Vietnam. In November, the North remains its late autumn climate. Temperatures drop further down to an average of 24°C, and the air becomes colder.
