Weather in May

In contrast to April's high rainfall, the weather in May sees a small drop in both rainfall and the quantity of rainy days. Consequently, the overall air pressure in the city stabilizes around 1008.8mb. Despite the slight decrease in precipitation, the relative humidity during the day continues hovering at a high level, contributing to the general dampness. Sunshine hours remain consistent, enabling city dwellers to enjoy daylight activities. As May progresses, one may expect a slight decrease in rainfall but the overall weather conditions remain relatively stagnant.

Temperature

May's presence records an average high-temperature of a still hot 32.3°C (90.1°F), closely mirroring April's climate. Throughout May, Kuala Lumpur records an average temperature of 23.8°C (74.8°F) at night.

Heat index

May's mean heat index is estimated at a burning hot 45°C (113°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
In reference to the heat index, it's for places in shade and with a slight wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
