Weather in May
Temperature
In Jamestown, the average high-temperature in May slightly rises, from a warm 77.9°F (25.5°C) in April, to a still moderately hot 84.7°F (29.3°C). Jamestown reports an average nighttime low-temperature of 63.9°F (17.7°C) in May.Heat index
For May, the heat index is evaluated at a tropical 93.2°F (34°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
