Weather in May
Temperature
The shift from April to May introduces a subtle increase in the average high-temperature, moving from 75.4°F (24.1°C) to a still moderately hot 82.4°F (28°C). During the May nights, an average temperature of 64°F (17.8°C) is observed.Heat index
May's average heat index is appraised at a tropical 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Observations indicate that the heat index values are for shady locations with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
