Weather in September
Temperature
The start of September signals a gentle decrease in the average high-temperature, transitioning from 94.6°F (34.8°C) in August to a still tropical 88.3°F (31.3°C). Throughout the month of September, Langston sees a steady low-temperature average of 67.3°F (19.6°C).Heat index
The heat index in September is computed to be a torrid 100.4°F (38°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
