Weather in August
Temperature
August, known for its average high temperature of 95.9°F (35.5°C) and an average low temperature of 76.8°F (24.9°C), is the warmest month.Heat index
The heat index for August is appraised at a blazing hot 113°F (45°C). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
