The summer and monsoon seasons of Hanoi are hot, oppressive, and wet. There are thunderstorms and slight drizzles which continue for long hours. This makes it even more difficult to venture out and explore the city landscapes. May, however, is still not too hot as compared to the other summer months. The temperature in May is around 28 degrees Celsius, and the skies are still relatively clear.
However, with the onset of June, the summer begins in full force, with temperatures ranging from 29-33 degree Celsius. The highest temperatures in summer could also touch 40 degrees. June is usually the hottest month and also the month when the rainfall starts. July and August see the maximum rainfall that is usually as high as 200mm and more.
The average temperature in July and August averages around 29 degrees. In September there is a slight fall in temperature averaging at 27 degrees and rainfall dips to a little more than 150mm. However, throughout the summer months, the humidity remains high crossing 75%. The high temperatures coupled with rain are the main reasons why the summers are considered Hanoi’s offseason. However, this means that the tariffs are less and accommodations and bookings easier and more affordable.
Tips for Travellers
Armed with a raincoat and umbrella, one can catch a few hours of outdoors sunshine, yet the unpredictable climate can make planning sightseeing tours go off in minutes. However, there are plenty of indoor activities to keep one busy in Hanoi too. Enrol in a cooking class or watch the rain drizzle from the window of a café while reading your favourite book. Besides, there are also a few festivals during the monsoon and summer months that can excite travellers to take the sweaty plunge.
Festivals in Summer
The Chem Temple Festival in June which involves a water procession which consists of Dragon boats, the bullfighting festival of Do son Buffalo in August and the Dong Nhan Temple Festival are some of the monsoon festivals of the city.
However, the most popular festival of this season is the fun-filled Mid-Autumn Festival celebrated in September. The lakes of Hanoi are especially beautified and thronged by locals and tourists, as lanterns soar to the sky and puppet shows, lion dances and exciting food stalls get crowded on the ground.
