Temperature

August, on average, is the coldest month, registering a high temperature of 28.7°C (83.7°F) and a low of 25.5°C (77.9°F).

Heat index

During August, the heat index is appraised at a torrid 35°C (95°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. 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 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
