Weather in September
Temperature
The shift into September records an average high-temperature of a still hot 88.5°F (31.4°C), subtly varied from August's 91.4°F (33°C). Throughout September nights, Emporia registers an average low-temperature of 73.8°F (23.2°C).Heat index
September's heat index is computed to be a blisteringly hot 105.8°F (41°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.One should consider that heat index numbers are for shaded settings and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
