Weather in August
Temperature
The arrival of August sees an average high-temperature of a still tropical 88.3°F (31.3°C), hardly diverging from July's 89.6°F (32°C). In Effingham, the August nights cool down to an average low of 71.2°F (21.8°C).Heat index
In August, the average heat index is appraised at a blisteringly hot 105.8°F (41°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Always consider that heat index estimations are for light winds and places in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
