Weather in May
Temperature
As May takes hold, the average high-temperature is a still tropical 31.5°C (88.7°F), nearly mirroring that of the previous month. Nighttime temperature lowers to an average of 26.3°C (79.3°F) in May.Heat index
In May, the average heat index is evaluated at an extremely hot 41°C (105.8°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
