Weather in September
Temperature
The arrival of September brings an average high-temperature of a still hot 34.9°C (94.8°F), closely following the temperature pattern of August. During September, an average low-temperature of 24.7°C (76.5°F) is observed.Heat index
September's mean heat index is evaluated at a blazing hot 45°C (113°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
