July is summer in the North of Vietnam, the hot and dry season in the Central Coast of Vietnam, the rainy season in the Central Highlands and South of Vietnam. June and July are the two hottest month in the North and the Central Coast of Vietnam.
July is a great time for family holidays and beach vacations on the Con Dao Islands and the Phu Quoc Island off the shore of southern Vietnam. During this time the sun shines everyday, the sea is calm and clear, it rains for only half an hour daily then stops, and the temperatures are pleasant (26-31oC).
The winds which affect Vietnam in July include:
- The Southeasterly Wind in the North of Vietnam which causes rain and nice temperatures.
- Westerly/Southwesterly Wind in the extreme Northwest of Vietnam, sometimes in the lowlands in the North, in much of the Central Coast of Vietnam which is also known as the foehn wind that causes heat strikes in these regions;
- Southwesterly Wind in the Central Highlands and the South of Vietnam which is moist and pleasant and which causes daily short-lived rain;
The Southwesterly Wind helps to make up the rainy season in the Central Highlands and South of Vietnam and nice temperatures in these regions in July; it is the same wind that causes hot and dry weather in the Central Coast of Vietnam and parts of North Vietnam due to the foehn effect.
In July the Northeast of Vietnam has occasional rain, sunshine and often pleasant temperatures (25-33oC). The Northwest of Vietnam often has heat strikes and strong sun, heavy occasional rain (26-370C). The lowlands of northern Vietnam have mixed heat strikes, pleasant temperatures and t-storms (28-37oC).
The Central Coast has some rain, but mostly strong sun and high temperatures (28-38oC). The northern region (to the north of the Hai Van Pass) of the Central Coast from Thanh Hoa to Hue often has higher temperatures and heat strikes. The region to the south of the Central Coast from Da Nang to Phu Yen often has bright sunshine and nicer temperatures (25-35/36oC).
The Central Highlands often have daily rain and nice temperatures (20-28oC).
The South of Vietnam has daily rain and nice temperatures (24-33oC).
Both the Con Dao Islands and Phu Quoc Island have nice weather with sun, clouds, daily short-lived rain, pleasant temperatures (26-31oC).

The temperatures were nice in the extreme Northwest (Son La, Dien Bien and Lai Chau) though. In the middle of the second week heavy rain in Lai Chau caused landslides on several roads; a flash flood at Tan Uyen destroyed agricultural crops and houses. It was mostly dry in the lowlands in the North and in the Central Coast.
