Weather in August
Temperature
The month of August, characterized by an average high of 94.6°F (34.8°C) and a low of 73.9°F (23.3°C), is recognized as the warmest.Heat index
For most parts of August, the heat index is appraised at a blistering 109.4°F (43°C). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
