Weather in September
Temperature
During September, Rayne observes a subtle ascent to a still tropical 86.5°F (30.3°C) from August's 89.6°F (32°C) in the average high-temperature. Nighttime temperatures in September average to a pleasant 70.5°F (21.4°C).Heat index
September's heat index is calculated to be a torrid 100.4°F (38°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.One should consider that heat index numbers are for shaded settings and light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
