Weather in September
Temperature
Welcoming September, East Lake notes an average high-temperature of a still hot 86.7°F (30.4°C), nearly consistent with August's 88.3°F (31.3°C). September nights are marked by an average low-temperature of 77.5°F (25.3°C).Heat index
September's mean heat index is evaluated at a torrid 98.6°F (37°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'real feel', is an estimation of the warmth sensation when considering humidity levels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
