Weather in August
Temperature
With August's arrival, Vienna notes an average high-temperature of a still tropical 89.2°F (31.8°C), closely following the trend of the preceding month. Throughout August, an average low-temperature of 72.7°F (22.6°C) is experienced.Heat index
The heat index value for August is appraised at an extremely hot 107.6°F (42°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. 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 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
