Weather in August

August, the last month of the summer in Nolensville, is another tropical month, with an average temperature fluctuating between 87.4°F (30.8°C) and 68.2°F (20.1°C).

Temperature

The shift from July to August is characterized by an average high-temperature of a still hot 87.4°F (30.8°C), not significantly different from the 88.3°F (31.3°C) of July. Throughout the month of August, Nolensville witnesses an average low-temperature of 68.2°F (20.1°C).

Heat index

August's average heat index is calculated to be a very hot 100.4°F (38°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
