Weather in May
Temperature
The start of May brings a subtle rise in the average high-temperature, moving from 78.3°F (25.7°C) in April to a still moderately hot 84.4°F (29.1°C). Mason, during the month of May, experiences an average low-temperature of 64.4°F (18°C).Heat index
For most parts of May, the heat index is appraised at a tropical 89.6°F (32°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
