Temperature

The advent of May signifies a minor shift to an average high-temperature of a tropical 32.6°C (90.7°F), aligning closely with April. During May, the temperature tends to dip to an average of 25.4°C (77.7°F) at night.

Heat index

For most parts of May, the heat index is computed to be a scorching 44°C (111.2°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

In May, the average relative humidity is 74%.
