Weather in May
Temperature
Mandeville's transition into May sees a mild rise in the average high-temperature, edging from 77.5°F (25.3°C) in April to a still warm 84°F (28.9°C). Throughout May, Mandeville encounters an average temperature drop to a pleasant 68.2°F (20.1°C).Heat index
The average heat index in May is calculated to be a tropical 91.4°F (33°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
