Weather in May
Temperature
With the onset of May, the average high-temperature subtly transitions from a warm 78.4°F (25.8°C) in April to a still moderately hot 85.3°F (29.6°C). During the nights in May, Pierce experiences a consistent average temperature of 69.1°F (20.6°C).Heat index
May's mean heat index is evaluated at a torrid 96.8°F (36°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
