Weather in August
Temperature
The onset of August notes an average high-temperature of a moderately hot 84.9°F (29.4°C), subtly shifted from July's 86.4°F (30.2°C). Brussels observes an average nighttime low-temperature of 66.4°F (19.1°C) during the month of August.Heat index
August's heat index is calculated to be a torrid 95°F (35°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Note that heat index values are valued for light wind and location in the shade. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Sunshine

A UV Index value of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for ordinary individuals.Note: In August, the maximum UV index of 6 transforms into these recommendations:
Deter overexposure. Protecting against the sun's effects is essential. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
