Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a still tropical 86.9°F (30.5°C) from August's 90.3°F (32.4°C). The average temperature in Greenwood drops to an agreeable 69.8°F (21°C) during the night in the month of September.Heat index
In September, the heat index is appraised at a very hot 100.4°F (38°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
