Weather in August
Temperature
With the start of August, Edison measures an average high-temperature of a still warm 82.6°F (28.1°C), not significantly differing from July's 84°F (28.9°C). August nights in Edison are marked by an average temperature drop to a comfortable 67.5°F (19.7°C).Heat index
The heat index value for August is evaluated at a hot 87.8°F (31°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Note that heat index values are valued for light wind and location in the shade. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
