Temperature

The onset of August brings a minor temperature shift, with the average high-temperature moving from a tropical 33.4°C (92.1°F) in July to a fiery hot 36.6°C (97.9°F). Cacoal undergoes a major shift from daytime highs, averaging a pleasant 21°C (69.8°F) during the night in August.

Heat index

In August, the average heat index is computed to be a scorching 42°C (107.6°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Being careless can result in skin and eye damage. Always take the necessary safety measures. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
