Weather in August
Temperature
The introduction of August notes a subtle temperature variation to a moderately hot 85.6°F (29.8°C) from July's 87.3°F (30.7°C). With a notable disparity from daily peak temperatures, the average low-temperature in Coal Grove settles at a refreshing 62.8°F (17.1°C) throughout August.Heat index
The heat index in August is calculated to be a torrid 96.8°F (36°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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 human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
