August, the last month of the summer in Seymour, is another hot month, with an average temperature fluctuating between 66°F (18.9°C) and 86.2°F (30.1°C).

Temperature

Stepping into August, Seymour records an average high-temperature of a still hot 86.2°F (30.1°C), almost consistent with July. Seymour throughout August, records an average low-temperature of 66°F (18.9°C).

Heat index

August's mean heat index is estimated at a very hot 96.8°F (36°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
