Weather in August

August, the last month of the summer in Philadelphia, is also a hot month, with an average temperature varying between 86.5°F (30.3°C) and 64.2°F (17.9°C).

Temperature

August's weather displays an average high-temperature of a still tropical 86.5°F (30.3°C), slightly varied from July's 87.3°F (30.7°C). Philadelphia documents a significant temperature variance in August, with the mean nighttime lows settling at an enjoyable 64.2°F (17.9°C).

Heat index

August's mean heat index is calculated to be a sweltering 98.6°F (37°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
