Weather in August
Temperature
Willow Grove witnesses its peak temperatures during July and August, when the average high-temperature reaches 89.8°F (32.1°C).Heat index
For most parts of August, the heat index is estimated at a blistering 111.2°F (44°C). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Guard against overexposure. Protection from sun-induced harm is essential. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
