Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a still hot 87.8°F (31°C), showing little divergence from the previous month's conditions. Pennington encounters a steady low-temperature average of 67.1°F (19.5°C) throughout the month of September.Heat index
September's average heat index is evaluated at a torrid 102.2°F (39°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
