Weather in September
Temperature
The transition into September marks the average high-temperature at a still hot 88.7°F (31.5°C), differing minimally from August's 93.7°F (34.3°C). September brings Lyles Addition a consistent average low-temperature of 68.7°F (20.4°C).Heat index
September's average heat index is calculated to be a blisteringly hot 105.8°F (41°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
