Weather in August

August, the last month of the summer in Westchester, is also a hot month, with temperature in the range of an average high of 86°F (30°C) and an average low of 78.4°F (25.8°C).

Temperature

The shift into August reveals an average high-temperature of a still hot 86°F (30°C), closely mirroring July's climate. Westchester maintains an average low-temperature of 78.4°F (25.8°C) throughout August's nights.

Heat index

The heat index value during August is estimated at a torrid 98.6°F (37°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
