Weather in September
Temperature
The arrival of September marks a slight shift to an average high-temperature of a moderately hot 85.5°F (29.7°C) from August's 90.1°F (32.3°C). During September, the average low-temperature is a pleasant 69.3°F (20.7°C).Heat index
During September, the heat index is appraised at a torrid 96.8°F (36°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.The standards for the heat index are set for locations in shade and under light breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
