Weather in September
Temperature
September is marked by a subtle drop in average high-temperatures, transitioning from a tropical 94.3°F (34.6°C) in August to a still hot 86.5°F (30.3°C). Junction, during the month of September, experiences an average low-temperature of 68.2°F (20.1°C).Heat index
Throughout September, the heat index is evaluated at a tropical 93.2°F (34°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
