Weather in August
Temperature
The transition into August is marked with an average high-temperature of a still tropical 87.4°F (30.8°C), showing an insignificant shift from July's 90°F (32.2°C). Jamestown's average low-temperature is measured at a comfortable 67.6°F (19.8°C) during August.Heat index
August's heat index is estimated at a very hot 100.4°F (38°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
