Weather in September
Temperature
With September's arrival, Orrville notes an average high-temperature of a still tropical 87.6°F (30.9°C), closely following the trend of the preceding month. During September, the average low-temperature is a comfortable 67.1°F (19.5°C).Heat index
The heat index for September is estimated at a very hot 100.4°F (38°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
