August weather forecast
Óbidos, Brazil

August, the last month of the winter in Óbidos, is a fiery hot month, with an average temperature fluctuating between 35.1°C (95.2°F) and 23.8°C (74.8°F).

Temperature

As August takes hold, the average high-temperature is a torrid 35.1°C (95.2°F), nearly mirroring that of the previous month. Throughout August, the temperature falls to an average low of 23.8°C (74.8°F).

Heat index

August's average heat index is evaluated at a life-threatening hot 45°C (113°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

In August, the average relative humidity is 60%.

UV index

Note: In August, the average maximum UV index of 7 translates into the following recommendations:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
