Weather in May
Temperature
May showcases a minor temperature ascent, adjusting from April's 73.9°F (23.3°C) to a still warm 80.6°F (27°C). An average nighttime temperature of 63.1°F (17.3°C) is observed in Saint Stephen during May.Heat index
For most parts of May, the heat index is computed to be a hot 86°F (30°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
