Laos has two climate seasons, dry season (October to late April) and a wet season (May to late September), among which, March/April of dry season and May/June of wet season are usually being the hottest periods of the year.

The Mekong River valley, where at its lowest, has higher humidity and temperatures in excess of 35°C are not uncommon even in the hottest season of the year.
The early months of the wet season (May – July) remain very hot and rainfall is often short lived, whilst in the latter months (late July – September) the rains tend to get more constant and can be heavy at times, especially in southern parts of the country. Further north and in Luang Prabang, rainfall tends to be lighter and you can often expect rain during the night or mornings with some relatively clear afternoons. Across Laos, throughout much of the rainy season, daytime temperatures average around 29°C in the lowlands and 23°C in the mountain valleys.
Throughout the country in all but the hottest months of the year it is often advisable to have a jumper or fleece for the evenings, when there is a tendency for it to get quite cool.
