Weather in September
Temperature
September indicates a minor shift in the average high-temperature, from August's 93.4°F (34.1°C) to a still hot 87.3°F (30.7°C). The average low-temperature of 65.8°F (18.8°C) is witnessed in Waldo during September.Heat index
The heat index in September is calculated to be a torrid 98.6°F (37°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke 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 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
