Weather in August
Temperature
Harrisburg experiences a subtle adjustment in high-temperatures to a still tropical 87.3°F (30.7°C) with the onset of August, maintaining near parity with July's 89.1°F (31.7°C). During the nights in August, Harrisburg observes an average low-temperature of 70.2°F (21.2°C).Heat index
Throughout August, the heat index is calculated to be a torrid 102.2°F (39°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
