What is the weather like from June to August?
at 3:12 am
This time is the summer in Vietnam. Like other northern provinces in Vietnam, Hanoi’s climate is characterized by hot and sunny. The temperature fluctuates from 30-36 Celsius degree. Thus, personally, I think it is the favorable time for you to travel to Hanoi. However, one thing is noted that although day time in Hanoi is sunny, but in evenings, there is often sudden rain, so it is had better for you to bring a small umbrella.
