Similar to Northern Vietnam’s weather, Phong Nha – Ke Bang National Park has a typical tropical monsoon weather with hot temperature in summer and high humidity. In summer it can go up to 41°C and it also can drop as low as 6°C in winter. As such, it is not advisable to go there during typhoon and rainy season, especially from October to December, although the temperature inside the cave is still cool (around 20°C) but the temperature outside is simply unbearable. You may not be easy and comfortable with rain or bad weather or typhoon during the month of October to December as the weather can turn cold.

So, we recommend to visit or join adventure tour in Phong Nha – Ke Bang National Park from February to August, the weather is more ideal
