March weather forecast
Laos

March in Laos is characterized by a significant shift in climate, marking the beginning of the hot season. As the month progresses, temperatures rise considerably, and the climate begins to transition from the dry and cooler conditions of February to the hotter, more oppressive weather conditions that prevail from March until mid-May.

Vientiane, the capital city situated in the center-south region of the country, experiences considerable heat during March. Average high temperatures in Vientiane can reach up to 34°C (93.2°F) during the day, one of the highest temperatures of the year. This rise in temperature is pronounced due to the city's geographical location in the low-lying plains near the Mekong River.

In the northern region around Luang Prabang, temperatures also start to increase in March, though they are slightly more moderate compared to Vientiane due to the surrounding mountains. Daytime highs in this region can reach up to 30°C (86°F), but nights remain somewhat cool, particularly at higher altitudes.

Compared to the preceding month of February, March is significantly hotter. The increase in heat is notable and can feel quite oppressive, particularly in the central and southern regions of Laos. Despite the rise in temperature, rainfall remains minimal as the dry season persists throughout March. However, the average relative humidity begins to increase from a low of 66% in February to a higher level in March, indicating the start of the transition towards the rainy season.

While the sun continues to shine for 8 to 9 hours a day, the sun's ultraviolet index starts to reach dangerous levels, often hitting the high zone of 11 to 12. Therefore, precautions for sun protection become essential during this period.

March does not hold any record for the extreme temperatures in Laos, but it is noteworthy for the stark transition it represents from the cool dry season to the onset of the hot season. This time of year is considered challenging for outdoor activities due to the high heat and sun exposure.
