Laos - Vientiane Weather Forecast

With regards to climate and weather in Laos, it should be noted that there is some variation as different parts of the country are at different altitudes. In general, however, Laos is a tropical country where there is a tropical monsoon wet/rainy season from July through October during which it is usually hot and humid and a dry season from November through June when the humidity is reduced. March to May is a period of very hot weather in the lowlands but moderate temperatures in the highlands.

The best time to go to travel Laos weather-wise, is probably between November and February when it is not too hot or too rainy - although it is quite cold in the highlands in December and January. Roads may be flooded and inaccessible in remote areas during the rainy season but travel by river is possible during this time. November, however, is the best time to travel by river as flooding has subsided but water levels are still high enough for boats.
