Heat index

The average heat index in September is computed to be a blisteringly hot 43°C (109.4°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Heat index values are typically calculated for conditions of shade and a light breeze. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 are largely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

September and October, with an average relative humidity of 82%, are the most humid months.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
