Temperature

August is the warmest month, with the temperature often reaching an average high of 30.9°C (87.6°F) and an average low of 21.3°C (70.3°F).

Heat index

The heat index value during August is evaluated at a fiery hot 39°C (102.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
