Weather in August
Temperature
The advent of August denotes an average high-temperature of a still moderately hot 81.1°F (27.3°C), subtly different from July's 82.6°F (28.1°C). During the month of August, Atlantic experiences a steady low-temperature average of 62.2°F (16.8°C).Heat index
For August, the heat index is estimated at a hot 86°F (30°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
