Hue and Hoian are yet to be on the peak of the hot season but temperatures may rise to 35°C (95°F) in the midday. Also, it is drier with little rain.
Nha Trang is still in great conditions for a perfect retreat while Ho Chi Minh city is entering the rainy season. This south’s largest city observes more downpours but they happen very quickly and do an excellent job in lowering the daytime heat. Make sure to find a good hide if you see black cloud suddenly appearing on the sky.
