Weather in September
Temperature
Centenary records an average high-temperature of a still hot 87.1°F (30.6°C) in September, closely mirroring the climate of the previous month. The average nighttime temperature in Centenary lowers to a pleasant 68°F (20°C) throughout September.Heat index
The heat index value during September is calculated to be a torrid 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
