Heat index

In May, the average heat index is estimated at a sweltering 36°C (96.8°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
