In June, Vietnam experiences frequent rain, intense heat and occasional typhoons, making it less ideal for travel.

Sweltering Heat in Most Areas

In June, most parts of Vietnam are quite hot.

For example, in Hanoi, a famous travel destination in the north, daytime highs typically range from 32 to 36 degrees Celsius (90 to 97 degrees Fahrenheit), with extreme cases reaching up to 42℃ (108℉). Under such conditions, asphalt roads may appear nearly molten, and despite the use of umbrellas for shade, radiant heat wraps around the body like a damp towel, resulting in profuse sweating even after short periods of walking outside. Even at night, the lows are between 26 and 30℃ (79 to 86℉), which means that if you want to sleep comfortably, you must have a fan or air conditioner.

Fortunately, Vietnam still offers a few favorable highland destinations for escaping the summer heat. In the north, Sapa enjoys a cooler climate with temperatures ranging from 25 to 32℃ (77 to 90℉). A walk in the mountains accompanied by a cool breeze dispels all the heat and discomfort. In the south, Da Lat’s nighttime lows range from 26 - 28℃ (79 - 82℉), and the daytime highs hover around 32 - 34℃ (90 - 93℉). Whether you’re hiking or enjoying the floral landscapes, the climate ensures a relatively comfortable experience without the annoyance of profuse sweat.

High Precipitation & Typhoon Season Kicks off

Average precipitation: 213mm from 14 rainy days

The rainy season brings about more frequent and prolonged rainfall, ranking June among the months with the highest rainfall year-round.

In Ho Chi Minh City, for instance, June records a total rainfall of 312 mm on average, with approximately 20 days experiencing precipitation. During your trip, it’s very likely that you will encounter one or two short showers every day. Also, the rain here is not only heavy, but also comes with startling suddenness. One moment the sun is shining brightly, and the next, pea-sized raindrops pour down abruptly. Within seconds, puddles form on the pavement, leaving you trapped in a coffee shop before you have a chance to respond. However, the rain does not last long, and it can bring a brief coolness that relieves you from the sweltering heat.

What’s more, June marks the beginning of the typhoon season, during which typhoon activities are not yet intense. In the past five years, only two typhoons have been recorded in this month. However, once they strike, they can cause extremely heavy precipitation.

Ho Chi Minh City Before Typhoon

For example, Typhoon “Butterfly” in June 2025 brought over 800 mm of precipitation to Hue in a single day, more than twice the annual rainfall of Los Angeles. As a result, flights and ferries were cancelled, and water activities were also suspended. Fortunately, the impact area of typhoons is relatively small and the duration is short. By paying attention to weather forecasts in advance and avoiding the typhoon-affected period, the disruption to your itinerary can be minimized to the greatest extent.
