Weather in August
Temperature
Transitioning from July to August, Old Town observes an average high-temperature of a still tropical 88.3°F (31.3°C), differing subtly from the previous month. During the month of August, Old Town experiences a steady low-temperature average of 76.3°F (24.6°C).Heat index
The heat index value for August is evaluated at a blisteringly hot 104°F (40°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
