Weather in September
Temperature
The onset of September brings with it an average high-temperature of a still tropical 88.7°F (31.5°C), showing a negligible variation from the month before. Zellwood records an average nighttime low-temperature of 74.1°F (23.4°C) throughout September.Heat index
In September, the heat index is evaluated at an extremely hot 105.8°F (41°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
