Weather in September
Temperature
The commencement of September indicates a gentle shift in the average high-temperature, receding from August's 93.7°F (34.3°C) to a still tropical 88°F (31.1°C). The nighttime temperature dips to an enjoyable 66.7°F (19.3°C) on average during September.Heat index
September's mean heat index is estimated at a torrid 98.6°F (37°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
