In May, Clement notes an average high-temperature of a still moderately hot 28.8°C (83.8°F), maintaining the same climate as the preceding month. May nights observe an average temperature dip to a pleasant 22.3°C (72.1°F).

Heat index

For May, the heat index is estimated at a fiery hot 37°C (98.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
