May weather forecast
Ban Nagnôm, Laos

With May, the intensity of summer is at its peak in Ban Nagnôm. The sky becomes cloudier, holding back some sunshine, nevertheless, the days continue to lengthen, heating up the atmosphere. The humidity escalates, causing a distinct increase in rainfall, which now measures 116mm (4.57"), almost thrice the amount in April. May brings along the primary indications of the rainy season, with a drastic change compared to drier and hotter April weather.

Temperature

The shift into May uncovers an average high-temperature of a hot 33.8°C (92.8°F), subtly different from the previous month. In Ban Nagnôm, an average nighttime temperature of 23.6°C (74.5°F) is expected during May.

Heat index

For most parts of May, the heat index is estimated at a burning hot 48°C (118.4°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
