Weather in August
Temperature
Grayson sees the arrival of August with an average high-temperature of a still hot 93.2°F (34°C), indicating a subtle variation from July. Grayson anticipates an average minimum temperature of 73°F (22.8°C) in the month of August.Heat index
For most parts of August, the heat index is estimated at a life-threatening hot 120.2°F (49°C). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
