May weather forecast
Luang Prabang, Laos

In May, Luang Prabang steps into the reins of the wet season. Although temperature slightly decreases to 33.8°C (92.8°F), a notable upturn in rainfall happens as it fortifies from 108mm (4.25") to 147mm (5.79"), making May one of the wettest months. Increased cloud cover leads to a decrease in sunshine hours despite a steady amount of daylight. Humidity rises significantly due to the increased rainfall, creating a substantial moisture-laden environment. A slight reduction in the UV index brings some respite amidst the heightened temperatures and rainfall.

Heat index

For most parts of May, the heat index is computed to be a blazing hot 52°C (125.6°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
Know that the heat index computations account for shaded terrains and slight winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. After every outdoor workout or swim, liberally apply and frequently reapply a broad-spectrum SPF 30+ sunscreen.
