Weather in September
Temperature
August's transformation into September witnesses an average high-temperature of a still tropical 86.5°F (30.3°C), noting a minor change from the preceding month. An average nighttime temperature of 74.1°F (23.4°C) is observed during September.Heat index
September's average heat index is evaluated at a torrid 98.6°F (37°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
