Weather in August
Temperature
Summit experiences an average high-temperature of a still moderately hot 80.8°F (27.1°C) with the onset of August, subtly varied from July's 81.5°F (27.5°C). Summit's average low-temperature in the month of August is recorded at a refreshing 59.4°F (15.2°C).Heat index
In August, the heat index is computed to be 84.2°F (29°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
