Weather in August
Temperature
With the onset of August, the average high-temperature stands at a still hot 88.3°F (31.3°C), closely aligned with July's 89.2°F (31.8°C). The average temperature during August nights in Saint Helena is registered at an agreeable 71.8°F (22.1°C).Heat index
The heat index value for August is computed to be a blistering 107.6°F (42°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
