Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a still tropical 86.7°F (30.4°C) from August's 90.7°F (32.6°C). Fair Oak Springs, during September nights, observes an average temperature of 67.8°F (19.9°C).Heat index
The heat index value during September is appraised at a fiery hot 100.4°F (38°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.The standards for the heat index are set for locations in shade and under light breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
