September's weather in detail

Whilst rainfall can still be expected throughout Laos during September, there is an end in sight and there are fewer wet days as the month progresses. Following months of rain, the lush green countryside around Vang Vieng and Muang La is at its most picturesque in September, and the waterfalls around the 4000 Islands at their most impressive. 

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