Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a still hot 32.5°C (90.5°F) from August's 30.8°C (87.4°F). The average low-temperature of 22.5°C (72.5°F) is witnessed during September.Heat index
During September, the heat index is computed to be an extremely hot 44°C (111.2°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Heat index details are generally centered around shaded locations and a mild breeze. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
