Weather in May

May signals the onset of true monsoon weather in Pakse, Laos as evidenced by the substantial rise in rainfall to 223mm (8.78"). The change is complemented by a small decline in average high temperatures, to a more comforting level. Humidity takes a significant surge, creating the moist and damp conditions characteristic of this tropical region's rainy season. Despite the wet atmosphere, daylight hours reach their peak for the year, alongside a constant UV index. Even though there is a decrease in sunshine hours, May retains substantial daylight time for various activities.

Temperature

Pakse starts May with an average high-temperature of a still hot 32.9°C (91.2°F), a minor shift from April's 34.8°C (94.6°F). Throughout the May nights, Pakse encounters a low-temperature of 24.9°C (76.8°F).

Heat index

May's average heat index is appraised at a blazing hot 45°C (113°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.
Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
