Weather in September
Temperature
Columbus's progression into September involves a minor drop in the average high-temperature, slightly receding from a sweltering 95°F (35°C) in August to a hot 88.3°F (31.3°C). During September nights, Columbus witnesses a consistent average temperature of 71.4°F (21.9°C).Heat index
For September, the heat index is calculated to be an extremely hot 104°F (40°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
