Weather in September
Temperature
Estelle's transition from August to September introduces an average high-temperature of a still tropical 86.5°F (30.3°C), marking an insignificant variation from the 89.4°F (31.9°C). In Estelle, in September, the average low-temperature is a moderately hot 76.3°F (24.6°C).Heat index
September's average heat index is appraised at a torrid 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 of high significance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
