Weather in September
Temperature
With the onset of September, a modest change to a still tropical 33.6°C (92.5°F) from August's 32.1°C (89.8°F) is noted in high-temperature. September generally records an average low-temperature of 22.2°C (72°F).Heat index
The heat index for September is computed to be a blisteringly hot 43°C (109.4°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.For clarity, heat index numbers account for light winds and areas under shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
