Weather in September
Temperature
September's presence records an average high-temperature of a still hot 88.3°F (31.3°C), closely mirroring August's climate. Cedar Mill Run, during the month of September, experiences an average low-temperature of 70°F (21.1°C).Heat index
September's heat index is calculated to be an extremely hot 105.8°F (41°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
