Heat index

In September, the average heat index is appraised at a scorching 44°C (111.2°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
Heat index evaluations are typically in the context of light winds and shaded environments. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Humidity

In September, the average relative humidity is 71%.
