Weather in August
Temperature
The arrival of August sees a recorded average high-temperature of a still moderately hot 82.9°F (28.3°C), showing little divergence from the previous month's conditions. During August, Tappan records an average temperature of 67.3°F (19.6°C) at night.Heat index
In August, the average heat index is calculated to be a tropical 87.8°F (31°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
