Weather in August
Temperature
The advent of August reveals an average high-temperature of a still tropical 91.6°F (33.1°C), showing minimal difference from the prior month. Throughout August nights, a significant departure from daytime temperatures, with an average low of 68.5°F (20.3°C), is recognized in White Rock.Heat index
The heat index value for August is estimated at an extremely hot 111.2°F (44°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.Always consider that heat index estimations are for light winds and places in the shade. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
