Weather in August
Temperature
August observes an average high-temperature of a still tropical 89.2°F (31.8°C), marking an insignificant difference from July's 90°F (32.2°C). During August, Shirley experiences an average low-temperature of 68.5°F (20.3°C) at night.Heat index
The heat index for August is computed to be an extremely hot 105.8°F (41°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
