Weather in May
Temperature
A slight uplift in the average high-temperature marks May, adjusting from April's warm 76.1°F (24.5°C) to a still moderately hot 82.2°F (27.9°C). Nighttime temperature dips to a mean of 72°F (22.2°C) during May.Heat index
For May, the heat index is appraised at a tropical 87.8°F (31°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Note that heat index values are valued for light wind and location in the shade. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
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. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
