Weather in May

The introduction of May sees an average high-temperature of a still warm 27.4°C (81.3°F), hardly deviating from April. During the May nights, an average temperature of 17.5°C (63.5°F) is observed.Heat index
In May, the heat index is evaluated at a tropical 30°C (86°F). With extended exposure and activity, one might feel exhausted and experience heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
