Weather in August
Temperature
Gwynedd's average high-temperature in August is a still warm 82.8°F (28.2°C), marking an insignificant difference from the 85.3°F (29.6°C) of July. Throughout the month of August, Gwynedd witnesses an average temperature of 65.3°F (18.5°C).Heat index
Throughout August, the heat index is appraised at a tropical 87.8°F (31°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 particularly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
