Temperature

August, marked by an average high-temperature of 30.7°C (87.3°F) and a low-temperature of 22.8°C (73°F), is the warmest month.

Heat index

The heat index in August is computed to be a blistering 41°C (105.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

In August, the average relative humidity is 82%.
