Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a torrid 95°F (35°C) in August to a hot 88.5°F (31.4°C). Throughout September, the average low-temperature in Cat Spring records at a pleasant 70.7°F (21.5°C).Heat index
The heat index value during September is computed to be a blisteringly hot 104°F (40°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
