Weather in September
Temperature
Texarkana's September weather shows a modest shift in high-temperatures, falling from August's tropical 93.7°F (34.3°C) to a still hot 88°F (31.1°C). Throughout September, Texarkana experiences a low-temperature average of 66.7°F (19.3°C).Heat index
In September, the average heat index is evaluated at a fiery hot 98.6°F (37°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 hold great significance to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. As body temperatures escalate without effective heat release, one might face dehydration threats.
