Vietnam Weather in July 2019

July is summer in the North and the Central Coast of Vietnam, the rainy season in the Central Highlands and South of Vietnam.

 July is often the hottest month in the eastern side of the Northwest (Hoa Binh, Yen Bai, Lao Cai), in the Red River Delta and the Central Coast of Vietnam (from Thanh Hoa to Phu Yen, Ninh Thuan). It is possible but not often hot in the Northeast and the extreme Northwest of Vietnam (Son La, Dien Bien, Lai Chau).

In July the far-northern mountains often have torrential rains and there are often flash floods. There may also be typhoons or tropical depressions brushing through Vietnam’s sea or inland in the North. It is best to consult local travel specialists if you want to take a trip into this region.

July is when the Central Coast suffers constantly from high temperatures (30-40oC) with very little rainfall. The region normally experiences serious droughts in July. Along with constant heat strikes and serious lack of water, there is a high danger of forest fires. It is often bright sunshine and intense ultraviolet in the Central Coast in July, make sure you have enough cover when traveling outdoors.

July is a lovely time in the Central Highlands and South of Vietnam with short-lived daily rains which last for about 1 hour more or less. While it is not often but there may be floods in the Central Highlands during this time. The temperatures are very pleasant, 20-30oC in the Central Highlands and 25-32oC in South Vietnam.

It rains daily (30 minutes or 1 hour) on the Con Dao Islands and Phu Quoc Island. The daily temperatures on these two islands are approximately 28-31oC. There are often days that the Southwesterly Monsoon is strong and the sea is rough from Binh Thuan to Ca Mau and from Ca Mau to Kien Giang, in the Rach Gia Gulf.

In July, the strong Southwesterly Monsoon means rough sea from Binh Thuan to Ca Mau and from Ca Mau to the Rach Gia Gulf, and considerable rainfalls in South Vietnam (including the offshore islands) and the Central Highlands of Vietnam. It is different in the Central Coast and North of Vietnam when the southwesterly wind is strong and dominating in these two regions, then it means heat strike with dry weather and high temperatures (30-40oC). This is because of the foehn effect.
