Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still hot 32.5°C (90.5°F), closely aligned with August's 33.2°C (91.8°F). Throughout September, an average low-temperature of 23.6°C (74.5°F) is experienced.Heat index
During September, the heat index is estimated at a burning hot 46°C (114.8°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.For clarity, heat index numbers account for light winds and areas under shade. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
