Heat index

The average heat index in May is evaluated at a torrid 36°C (96.8°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

The average relative humidity in May is 81%.

Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
