Laos: Weather & when to go: September

September overview

Although September is still considered to be part of the wet season, towards the end of the month, the dry season slowly emerges and this reduces both rainfall frequencies and average temperatures marginally (about 26°C in Vientiane and Luang Prabang). As a result, September can be a good time to visit as most landscapes remain green and fertile, whilst the weather conditions become more comfortable for tourists. Nonetheless, tourists should note that rainfall is still very common and humidity levels can reach 80% on a regular basis.
