Weather in September
Temperature
The onset of September aligns with a soft reduction in the average high-temperature, gently falling from a tropical 87.4°F (30.8°C) in August to a warm 80.6°F (27°C). During September, the temperature tends to dip to an average of 59.2°F (15.1°C) at night.Heat index
In September, the average heat index is computed to be 84.2°F (29°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
