Weather in September
Temperature
September's weather records an average high-temperature of a tropical 30.8°C (87.4°F), showing little deviation from August. In September, the average low-temperature is a pleasant 22.8°C (73°F).Heat index
Throughout September, the heat index is evaluated at a fiery hot 37°C (98.6°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
