Weather in August
Temperature
Saint Thomas starts August with an average high-temperature of a still hot 90°F (32.2°C), a minor shift from July's 90.1°F (32.3°C). August witnesses an average low-temperature hovering around a warm 74.8°F (23.8°C).Heat index
Throughout August, the heat index is appraised at a blazing hot 113°F (45°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
