Weather in September
Temperature
September brings a slight decrease in temperature, down from a hot 91.4°F (33°C) in August to a moderately hot 84.4°F (29.1°C). Jethro anticipates a stark contrast in temperature during September nights, with an average low of 62.6°F (17°C).Heat index
The heat index in September is evaluated at a hot 91.4°F (33°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Heat index readings emphasize conditions of light breezes and shaded spots. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to 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.
