Weather in May
Temperature
The beginning of May signals a minor rise in the average high-temperature, moving from a warm 75.7°F (24.3°C) in April to a still moderately hot 82.4°F (28°C). Ashburn, during the month of May, experiences an average low-temperature of 64.9°F (18.3°C).Heat index
For May, the heat index is appraised at a hot 87.8°F (31°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
