Temperature

August is the month that records the highest temperatures, with averages ranging from a high of 32°C (89.6°F) to a low of 24.7°C (76.5°F).

Heat index

The heat index for August is calculated to be a blisteringly hot 40°C (104°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
