Weather in August
Temperature
Cardiff starts August with an average high-temperature of a warm 85.5°F (29.7°C), hinting at a minimal fluctuation from July. Cardiff records a marked daily temperature contrast, with an average low-temperature of 63.9°F (17.7°C) during the nights of August.Heat index
The average heat index in August is estimated at a sweltering 96.8°F (36°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 great significance to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
