Weather in September
Temperature
The onset of September brings a small shift in high-temperatures, falling from a tropical 86.9°F (30.5°C) in August to a moderately hot 81°F (27.2°C). September's nights observe an average temperature of 59.9°F (15.5°C).Heat index
September's mean heat index is evaluated at a tropical 86°F (30°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
