Weather in August
Temperature
The commencement of August introduces an average high-temperature of a still moderately hot 82.9°F (28.3°C), closely mirroring the preceding month. Upper Saddle River records an average nighttime low of 65.7°F (18.7°C) in August.Heat index
Throughout August, the heat index is computed to be a hot 87.8°F (31°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
