Weather in September
Temperature
The advent of September observes an average high-temperature of a still hot 88°F (31.1°C), nearly identical to August's 91°F (32.8°C). September brings Fullerville a consistent average low-temperature of 74.1°F (23.4°C).Heat index
The heat index value during September is estimated at a blistering 104°F (40°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Always consider that heat index estimations are for light winds and places in the shade. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
