Weather in September
Temperature
With the onset of September, the average high-temperature registers at a still hot 87.6°F (30.9°C), subtly different from August's 91.6°F (33.1°C). During the month of September, Ruby's nighttime temperature lowers to an average of 68.5°F (20.3°C).Heat index
For September, the heat index is evaluated at a blistering 104°F (40°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
