Weather in September
Temperature
Manning experiences a subtle adjustment in high-temperatures to a moderately hot 83.8°F (28.8°C) with the onset of September, maintaining near parity with August's 88.9°F (31.6°C). During September, an average low-temperature of 67.1°F (19.5°C) is observed.Heat index
In September, the heat index is evaluated at a tropical 93.2°F (34°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
