Weather in August
Temperature
With its high average temperature of 95.5°F (35.3°C) and a low of 73.2°F (22.9°C), August is regarded as the warmest month.Heat index
For most parts of August, the heat index is computed to be a blazing hot 127.4°F (53°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
