Heat index

For September, the heat index is calculated to be a blistering 44°C (111.2°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
