Weather in July
Temperature
With July's arrival, Princeton's weather records an average high-temperature of a still tropical 93.9°F (34.4°C), marking little difference from June's 89.6°F (32°C). Princeton's temperature in July lowers to a consistent average of 75°F (23.9°C) during the nights.Heat index
For most parts of July, the heat index is calculated to be a burning hot 113°F (45°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
