April weather forecast
Laos

April in Laos is defined by its intense heat, as the hot season reaches its peak. This month stands as the hottest period of the year, with average high temperatures soaring, particularly in the central and southern regions of the country.

In Vientiane, the capital city located in the center-south, April experiences the highest average temperatures of the year, reaching a peak of 35°C (95°F). The city, owing to its geographical positioning in the low-lying plains near the Mekong River, witnesses a significant surge in temperature, creating oppressive heat during the day.

The northern region around Luang Prabang also faces high temperatures in April, although they are slightly more moderate due to the area's mountainous terrain. Daytime temperatures in this region can reach up to 33°C (91.4°F), while nighttime temperatures remain somewhat cooler, particularly in the high altitudes.

Compared to March, April witnesses a further rise in temperature, solidifying its status as the hottest month of the year. Although the dry season generally persists throughout April, the average relative humidity further increases, hinting at the approaching rainy season. Rainfall, however, remains minimal, with most regions receiving less precipitation than during the monsoon months.

Sunshine duration remains constant at 8 to 9 hours per day, similar to the preceding months. However, the sun's ultraviolet index stays in the dangerous zone of 11 to 12, urging a need for careful sun protection during outdoor activities. The intense heat and high ultraviolet index make it a challenging time for those unaccustomed to such conditions, especially in the central and southern plains.

Although April does not hold the records for the highest temperatures ever recorded in Laos, it is the month with the highest average temperatures. Therefore, travelers are advised to prepare for the intense heat and sun exposure if they plan to visit Laos in April.
