The average heat index in September is appraised at an extremely hot 42°C (107.6°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Act with urgency in protecting yourself. Without it, skin and eyes can be harmed in no time. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
