Temperature

The advent of May sees the average high-temperature at a still tropical 31°C (87.8°F), subtly shifted from April's 31.8°C (89.2°F). An average nighttime temperature of 20.5°C (68.9°F) is witnessed throughout May.

Heat index

May's heat index is calculated to be a fiery hot 39°C (102.2°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
