When to go to Laos
Allowing for slight variations between the north and south, Laos experiences three seasons.
The best time to travel is from November through to April, when the weather is warm and dry with cool nights. Temperatures begin to rise in March, with the rains usually breaking sometime in May or June. September can be very wet and short tropical downpours are a possibility on most days in October and early November.
When to go to Cambodia
Cambodia is hot all year round, with very little rainfall between November and April.
The monsoon season starts in April and picks up in May, continuing until October. Visits are still possible during this period as the rain usually consists of only short, but heavy, downpours.
The optimum time to visit is November when humidity is low, the rivers and waterfalls are full and the countryside is at its most colourful.
