Weather in August

August, the last month of the summer in Arlington, is another tropical month, with an average temperature fluctuating between 91.2°F (32.9°C) and 74.7°F (23.7°C).

Temperature

August's climate shows a minor adjustment in average high-temperatures to a still tropical 91.2°F (32.9°C) from July's 91.6°F (33.1°C). In Arlington, an average nighttime temperature of 74.7°F (23.7°C) is expected during August.

Heat index

In August, the heat index is calculated to be a burning hot 116.6°F (47°C). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.
Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
