Weather in September
Temperature
The introduction of September notes a subtle temperature variation to a moderately hot 85.1°F (29.5°C) from August's 89.6°F (32°C). Danville reports an average low-temperature of 67.5°F (19.7°C) during the nights of September.Heat index
The average heat index in September is evaluated at a torrid 95°F (35°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.The standards for the heat index are set for locations in shade and under light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
