Weather in September
Temperature
Stepping into September, Leroy records an average high-temperature of a still tropical 88.5°F (31.4°C), almost consistent with August. During September, Leroy experiences a consistent low-temperature average of 68°F (20°C).Heat index
The average heat index in September is evaluated at a blisteringly hot 104°F (40°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
