Weather in September
Temperature
September ushers in a minute temperature change, with average high-temperatures reducing from August's tropical 90.1°F (32.3°C) to a moderately hot 83.5°F (28.6°C). Wooster records a steady low-temperature average of 63.1°F (17.3°C) during September.Heat index
During September, the heat index is computed to be a tropical 89.6°F (32°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
