Weather in September
Temperature
September's arrival subtly correlates with a reduction in the average high-temperature, down from a tropical 86.7°F (30.4°C) in August to a warm 81.1°F (27.3°C). In the month of September, the average low-temperature in Vestal usually rests at a refreshing 59.9°F (15.5°C).Heat index
The average heat index in September is evaluated at a tropical 86°F (30°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 are particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
