August weather forecast
Arenápolis, Brazil

August, the last month of the winter in Arenápolis, is another tropical month, with an average temperature ranging between max 34.3°C (93.7°F) and min 19.8°C (67.6°F).

Temperature

The arrival of August introduces a minor uplift in high-temperatures, adjusting from 30.9°C (87.6°F) in July to a still tropical 34.3°C (93.7°F). August, marked by an average low-temperature of 19.8°C (67.6°F), indicates a large temperature drop from the daytime peak.

Heat index

The heat index in August is appraised at a torrid 36°C (96.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
