Weather in August
Temperature
As Philadelphia welcomes August, the average high-temperature is noted at a still hot 86.5°F (30.3°C), closely aligning with the preceding month. Philadelphia reports a steady low-temperature average of 64.2°F (17.9°C) throughout August, revealing a large deviation from the daytime high.Heat index
August's mean heat index is evaluated at a sweltering 98.6°F (37°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
