August, the last month of the summer in Grayson, is another tropical month, with an average temperature fluctuating between 89.1°F (31.7°C) and 70.2°F (21.2°C).

Heat index

The heat index in August is computed to be a blisteringly hot 104°F (40°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
