Weather in September
In September, the cooling trend in temperatures signals the onset of the fall season in Whiteville. There's a steady decline in both maximum and minimum temperatures, but the city continues to experience a high rate of rainfall typical of the preceding summer months. A subtle decrease in hours of sunshine is noticeable as the weather transitions from summer to fall conditions. However, the fall equinox ensures that daylight hours and nighttime hours are nearly equal. In this month, the weather is a blend of moderately high temperatures and increased precipitation, ensuring the environment remains lush and green as the town prepares to transition into the cooler months.Temperature
The average high-temperature in September, at a moderately hot 82.6°F (28.1°C), reveals a modest deviation from August's 87.4°F (30.8°C). Whiteville's average low-temperature in September is measured at an enjoyable 66.6°F (19.2°C).Heat index
In September, the heat index is computed to be a tropical 89.6°F (32°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.Note that heat index values are valued for light wind and location in the shade. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
