Weather in September
Temperature
The introduction of September sees an average high-temperature of a still moderately hot 28.4°C (83.1°F), hardly deviating from August. Nighttime temperature lowers to an average of 18.8°C (65.8°F) in September.Heat index
The heat index value for September is estimated at a hot 33°C (91.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
