Weather in August
Temperature
The ushering in of August brings an average high-temperature of a still warm 81.9°F (27.7°C), closely mirroring the 83.1°F (28.4°C) of July. Rahway's temperature in August lowers to a consistent average of 68.4°F (20.2°C) during the nights.Heat index
The heat index value for August is calculated to be a hot 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
