September weather top tip

Visit Laos in September to enjoy lush green countryside (following months of rain), take advantage of end-of-season discounted hotel rates and make the most of fewer crowds.


September Overview

September’s weather conditions in Laos are similar to August, with a high probability of rain. Although as the month rolls on and dry season approaches the intense downpours become more infrequent and less severe, and sunshine gradually replaces overcast skies. The lush green countryside around Vang Vieng and Muang La is at its most picturesque in September following months of rain. 

Temperatures begin to drop slightly with averages of 26°C in Luang Prabang and Vientiane, and 27°C in Pakse and the southern provinces; humidity levels remain around 80%.
