Weather in September
Temperature
Gregory records a slight change with September's average high-temperatures adjusting to a still tropical 87.3°F (30.7°C) from August's 90.9°F (32.7°C). Gregory records a mean low-temperature of 78.1°F (25.6°C) in September.Heat index
September's average heat index is estimated at a sweltering 98.6°F (37°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
