Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a hot 87.4°F (30.8°C) in August to a moderately hot 80.6°F (27°C). September brings an average low-temperature of 61.3°F (16.3°C) to Meherrin.Heat index
The average heat index in September is computed to be 84.2°F (29°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
