May weather forecast
Kampong Kdei, Cambodia

As Cambodian weather swings full tilt into the rainy season in May, Kampong Kdei mirrors this trend. An observable uptick in cloud cover, coinciding with increased humidity, forecasts a particularly damp month. Rainfall increases significantly from that of April, appearing more frequently throughout the course of the month. May's increase in rainy days, as well as abundant cloud cover, results in a drop in sunlight hours. Despite this, the region continues to experience high temperatures comparable to the preceding months.

Temperature

Transitioning from April to May, Kampong Kdei observes an average high-temperature of a tropical 34.5°C (94.1°F), differing subtly from the previous month. Throughout May, an average nighttime temperature of 26.7°C (80.1°F) is experienced.

Heat index

The average heat index in May is appraised at a blazing hot 49°C (120.2°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
