Weather in September
Temperature
The dawn of September sees an average high-temperature of a still hot 32.1°C (89.8°F), subtly contrasting with August's 33.1°C (91.6°F). Throughout September, the nighttime temperature averages to a warm 25.3°C (77.5°F).Heat index
September's heat index is computed to be a burning hot 45°C (113°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
