Weather in July
Temperature
Westchester's July weather, with an average high temperature of 85.6°F (29.8°C) and an average low temperature of 68.7°F (20.4°C), tends to be the warmest of the year.Heat index
July's heat index is computed to be a torrid 95°F (35°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Guard oneself from overexposure. Defence against sun injury is vital. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Experience reduced UV exposure by about half when donning a wide-brim hat.
