Weather in August
Temperature
Boston records an average high-temperature of a warm 85.6°F (29.8°C) in August, closely mirroring the climate of the previous month. Boston's August nights cool down to an average low-temperature of 65.7°F (18.7°C).Heat index
The heat index value for August is appraised at a torrid 96.8°F (36°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
