Weather in September
Temperature
September's weather records an average high-temperature of a still hot 88°F (31.1°C), showing little deviation from August. During the nights in September, Jena experiences a consistent average temperature of 68°F (20°C).Heat index
During September, the heat index is computed to be a sweltering 102.2°F (39°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
