Weather in September
Temperature
The warmest period falls in September and October, when the average high-temperature reaches 30.9°C (87.6°F).Heat index
In September, the average heat index is appraised at a blistering 40°C (104°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
