Weather in August
Temperature
Denville's shift from July to August is accompanied by an average high-temperature of a still warm 81.3°F (27.4°C), a slight deviation from 83.1°F (28.4°C). The average temperature drops to a refreshing 63°F (17.2°C) during the night in the month of August.Heat index
The average heat index in August is evaluated at a tropical 86°F (30°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
