Weather in May
Temperature
The shift from April to May sees a slight increase in the average high-temperature, transitioning from a moderately hot 73.4°F (23°C) to a still warm 82°F (27.8°C). Princeton in May anticipates an average nighttime temperature of 61.9°F (16.6°C).Heat index
The heat index in May is evaluated at a tropical 87.8°F (31°C). With extended exposure and activity, one might feel exhausted and experience heat cramps.Heat index details are generally centered around shaded locations and a mild 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 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. 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 hold particular significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
