Weather in August
Temperature
Norristown signifies an average high-temperature of a still hot 90°F (32.2°C) in August, closely mirroring the 90.7°F (32.6°C) of July. During August, Norristown sees a mean low-temperature of 72.9°F (22.7°C).Heat index
August's heat index is calculated to be a scorching 109.4°F (43°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Heat index data is primarily for areas with shade and subjected to light winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 remain especially vital for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
