Where should you go in Laos in may when it comes to the weather?

Remember:
The climate in Laos in may ranges from good to tolerable depending on the region and city.

That month is not the best month to visit Laos. The weather in Nong Kiau, Louang Namtha, Houei Sai and Luang Prabang is ok but correct. The sun is not there all the time and you risk you to be soaked by rain often. Nevertheless, if you don't plan a pool & relaxation trip in Laos but rather visiting museums, this climate may be enough. In addition, there are surely fewer tourists at this time.

But it is finally better than in Phonsavan, Vang Vieng, Pakse, Thakhek, Savannakhet, Khong island (Don Khong) and Vientiane and surrounding areas where the climate is very bad. It is not advisable to visit these areas in may.
