Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still moderately hot 28.9°C (84°F), closely aligned with August's 28.8°C (83.8°F). Nighttime temperatures hover around an average low of 21.1°C (70°F) in September.Heat index

Prolonged activity may cause heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
