Weather in September
Temperature
The average high-temperature for September is a still hot 88°F (31.1°C), closely aligning with the temperature of the preceding month. During September, Columbia experiences a consistent low-temperature average of 67.8°F (19.9°C).Heat index
September's average heat index is computed to be a very hot 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
