For most parts of September, the heat index is computed to be an extremely hot 41°C (105.8°F). Apply extra caution, heat cramps and heat exhaustion could happen.

The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. As body temperatures escalate without effective heat release, one might face dehydration threats.
