With the onset of May, the average high-temperature registers at a still hot 32.3°C (90.1°F), subtly different from April's 32.9°C (91.2°F). Montelibano cools down to an average low-temperature of 23.3°C (73.9°F) throughout the month of May.

Heat index

The heat index value for May is computed to be a life-threatening hot 47°C (116.6°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
