Heat index

For September, the heat index is computed to be a blazing hot 47°C (116.6°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Understanding the heat index involves considering values for shaded locales 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 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Also note that objects like parasols or canopies might not provide complete sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
