Temperature

September, known for its average high temperature of 33.6°C (92.5°F) and an average low temperature of 22.1°C (71.8°F), is the warmest month.

Heat index

During September, the heat index is evaluated at a blazing hot 50°C (122°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
In reference to the heat index, it's for places in shade and with a slight wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
