Temperature

The beginning of August reveals an average high-temperature of a still hot 33.4°C (92.1°F), showing minimal deviation from the previous month. During August, Acará reports a marked contrast from daily peak temperatures, with an average nighttime reading of 21°C (69.8°F).

Heat index

August's heat index is calculated to be a blazing hot 49°C (120.2°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Note: A maximum high UV index of 7 in August translates into the following recommendations:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
