Heat index

During May, the heat index is computed to be a torrid 39°C (102.2°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
