Weather in August

This month amalgamates characteristic elements of the Austin summer, justifying its reputation for featuring the best weather of the season. Remaining hot and less humid, August paves the way for the moderately warm and increasingly rainy September.

With its high average temperature of 96.4°F and a low of 75.4°F, August is regarded as the warmest month.

Heat index

The heat index value for August is evaluated at a burning hot 116.6°F. Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
