Ninh Thuan Weather, Best time to visit

Ninh Thuan has a tropical monsoon climate with two seasons per year: dry season from late February through July, rainy season from late August through January. From December through January, Ninh Thuan experiences cool temperatures (18-22oC) and from May to August Ninh Thuan has hot temperatures (28-40oC)..

 From October through November, sometimes December, Ninh Thuan may be affected by tropical depressions or typhoons; tt is more likely to rain in Ninh Thuan during these occasions.The Po Klong Garai Cham Towers in Phan Rang Thap Cham, Ninh Thuan, Vietnam

Still, Ninh Thuan has the smallest rainfall in Vietnam with average rainfall of 700-800m per annum. The annual average rainfall of Vietnam is 1,500-2,000m. The reason is attributed to the terrain of Ninh Thuan with mountains encircling the province:
- The province is surrounded by high mountains: Nui Chua Mountain (1,040m) and Hon Ba Mountain (1,578m) to the Northeast and North;
- The Central Highlands (with series of highlands and high mountain peaks over 2,000m) to the west;
- The Kalon – Song Mao Nature Reserve (with peaks of 1,000-1,136m) to the southwest;

The winds can not bring moisture through those high mountains and hence little rain in Ninh Thuan. The temperatures in Ninh Thuan are always much higher than those in Khanh Hoa (adjacent to the north) and Binh Thuan (adjacent to the south) which are both have similar altitudes with Ninh Thuan, and of course much higher than those in the Central Highlands to the west with much higher altitudes.

The tricky point is that the coastline of Ninh Thuan runs northeast-southwest which is exactly the direction of the summer monsoon: the southwesterly monsoon. There is no chance for this wind to bring moisture into Ninh Thuan. In contrast, this moist wind after passing through the mountains coming into Ninh Thuan it makes the air hot and dry: the foehn effect – the summer is hot and dry. The northeasterly winter monsoon can not much have influence in Ninh Thuan as it is too far away.

With little rainfall the sea water off the shore of Ninh Thuan is saltier than those in other regions in Vietnam. Besides, the coastline of Ninh Thuan runs northeast-southwest; when the southwesterly monsoon blows it makes the water on the surface with less salt and with higher temperatures (hence lighter) to flow further away from the coast. The cold water with more salt underneath (because of being heavier) to emerge the the surface…
