Weather in September
Temperature
The advent of September sees the average high-temperature at a still tropical 86.9°F (30.5°C), subtly shifted from August's 91.4°F (33°C). During the nights in September, an average low-temperature of 67.1°F (19.5°C) is observed.Heat index
The heat index value for September is calculated to be a torrid 98.6°F (37°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. 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. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
