Weather in August
Temperature
As July transitions into August, King William records an average high-temperature of a still tropical 87.4°F (30.8°C), showing a gentle shift from the preceding month. King William experiences a mean low-temperature of 67.6°F (19.8°C) during August.Heat index
During August, the heat index is appraised at a torrid 100.4°F (38°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: During August, 6 as the daily maximum UV index converts into the following advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
