Heat index

For September, the heat index is estimated at a scorching 44°C (111.2°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
The heat index's values are generally associated with conditions in shade 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 'apparent temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
