Weather in September
Temperature
September's arrival aligns with a minor decrease in average high-temperatures, from August's torrid 95.7°F (35.4°C) to a tropical 88.7°F (31.5°C). Throughout the September nights, Deanville encounters a low-temperature of 70.5°F (21.4°C).Heat index
The heat index value for September is estimated at a sweltering 102.2°F (39°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. 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 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
