August weather forecast
Apatou, French Guiana

August brings a notable decrease in rainfall, receding to 66mm (2.6"), much lower than the dramatic showers of the wet season. Cloud cover wanes appreciably, allowing an increase in sunshine hours and a subsequent decline in overall atmospheric humidity. Hence, August paves the way for a drier climate, revealing the striking hues of the city after rigorous rainfall. The city's aquatic life, too, benefits from the reduced showers, sustaining in the rivers with balanced water levels. August signifies a shift towards the drier months, making it an enticing period for outdoor explorations.

Temperature

The arrival of August is marked by an average high-temperature of a still tropical 32°C (89.6°F), bearing a close resemblance to July. In the month of August, the nighttime temperature dips to a steady average of 22.3°C (72.1°F).

Heat index

The heat index for August is evaluated at a burning hot 45°C (113°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. 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. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

The average relative humidity in August is 82%.

UV index

July through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for ordinary individuals.
Note: In August, an average UV index of 7 transforms into the following instructions:
Shield from overexposure. Defense against sun-related harm is required. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
