April in Laos is hot, hot, hot! Being the final month of Laos' dry season, days are typically sunny and rain-free, although the odd shower should be expected towards the end of the month.
April is typically one of the hottest months of the year in Laos. It's not unlikely for the thermostat to hit 40°C, especially in Pakse and the 4000 Islands region in the south of the country, whilst temperatures hover around a rather warm 30°C in Vientiane and Luang Prabang. Despite high temperatures humidity levels remain around 70%.
Towards the end of the month showers become more likely as the wet season approaches, especially in the northern regions around Phongsali, although these tend to be infrequent and short lived and won’t affect travel.
Months of minimal rainfall mean the river levels are low at this time of year, making river cruising particularly problematic.
