Weather in September
Temperature
With the onset of September, the average high-temperature registers at a still tropical 87.1°F (30.6°C), subtly different from August's 89.2°F (31.8°C). During September, the temperature in Port Inglis is averaged to a low of 74.3°F (23.5°C) at night.Heat index
The heat index value during September is calculated to be a very hot 102.2°F (39°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
