Weather in August
Temperature
August, on average, is the warmest month, registering a high temperature of 31.3°C (88.3°F) and a low of 24.8°C (76.6°F).Heat index
The average heat index in August is computed to be an extremely hot 40°C (104°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
