Weather in August
Temperature
With the arrival of August, Arlington's average high-temperature registers at a still tropical 88°F (31.1°C), indicating a subtle variation from the previous month. Arlington's nighttime temperature in August falls to an average of 70.3°F (21.3°C).Heat index
In August, the heat index is estimated at an extremely hot 104°F (40°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
