Weather in May
Temperature
As May sets, the average high-temperature shows a slight increase, moving up from 76.5°F (24.7°C) in April to a still warm 84.7°F (29.3°C). Princeton encounters a steady low-temperature average of 63.5°F (17.5°C) throughout the month of May.Heat index
May's average heat index is computed to be a hot 93.2°F (34°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Consider that heat index readings are for situations in the shade and light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
