Temperature

Temperature readings reach their annual highs in May, averaging 34.3°C (93.7°F) and a minimum average of 29°C (84.2°F).

Heat index

May's mean heat index is calculated to be a blazing hot 47°C (116.6°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Precautions are essential; the risk of damage to unprotected skin and eyes is too high. 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. Enhance your sun protection with tightly woven, yet airy clothing.
