Heat index

For August, the heat index is evaluated at an extremely hot 40°C (104°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. 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. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
