Weather in August
Temperature
August's advent notes a subtle adjustment in average high-temperature to a still tropical 88.2°F (31.2°C) from July. South Boston experiences a mean temperature of 66.7°F (19.3°C) during August nights.Heat index
August's heat index is estimated at a sweltering 102.2°F (39°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
