Heat index

During September, the heat index is evaluated at a torrid 39°C (102.2°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: The maximum UV index of 7 during September translates into these guidelines:
Prevent overexposure. Protection from the sun's harmful effects is needed. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
