Weather in August
Temperature
Knightsen's shift into August sets the average high-temperature at a still tropical 87.4°F (30.8°C), a figure that deviates only slightly from July's 88.5°F (31.4°C). Despite soaring daytime temperatures, Knightsen registers a consistent average low-temperature of 57.4°F (14.1°C) in August.Heat index
August's mean heat index is estimated at a hot 93.2°F (34°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
