Weather in August

The last month of the summer, August, is another tropical month in Valide, French Guiana, with an average temperature fluctuating between 32.8°C (91°F) and 20.5°C (68.9°F).

Temperature

August's advent denotes a minor fluctuation in the average high-temperature to a still hot 32.8°C (91°F) from July's 31.1°C (88°F). Valide's August nights represent a significant downturn from the day's heat, with an average temperature of 20.5°C (68.9°F).

Heat index

For most parts of August, the heat index is appraised at a life-threatening hot 47°C (116.6°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

UV index

August through November, with an average maximum UV index of 7, are months with the highest UV index in Valide. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.
Note: During August, 7 as the daily maximum UV index converts into the following advice:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
