Weather in May

In May, the average heat index is appraised at a tropical 87.8°F (31°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
