Weather in September
Temperature
With September's advent, McIntosh sees an average high-temperature of a still hot 88.5°F (31.4°C), subtly shifted from August's 91.9°F (33.3°C). Nighttime temperature experiences an average drop to an agreeable 69.1°F (20.6°C) in September.Heat index
The heat index value during September is computed to be an extremely hot 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
