Weather in September
Temperature
September's arrival aligns with a minor decrease in average high-temperatures, from August's very hot 98.1°F (36.7°C) to a tropical 90.3°F (32.4°C). An average low-temperature of 73°F (22.8°C) is observed during September nights.Heat index
The heat index for September is evaluated at a blisteringly hot 104°F (40°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
