Weather in August
Temperature
August's beginning signals an average high-temperature of a still moderately hot 84.7°F (29.3°C), barely different from July's 85.6°F (29.8°C). Saint James anticipates a considerable daily temperature fluctuation in August, with low temperatures averaging a refreshing 61.3°F (16.3°C).Heat index
August's mean heat index is computed to be a hot 93.2°F (34°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
