Weather in September
Temperature
As August transitions into September, the average high-temperature rests at a still tropical 90.3°F (32.4°C), maintaining a close resemblance to the previous month. Indian Lake, in September, observes a steady average low-temperature of 78.6°F (25.9°C).Heat index
For most parts of September, the heat index is appraised at an extremely hot 105.8°F (41°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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 body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
