May's onset brings an average high-temperature of a torrid 35.4°C (95.7°F), showing a minute difference from April's 33.8°C (92.8°F). An average nighttime temperature of 30°C (86°F) is recorded during May.

Heat index

For most parts of May, the heat index is computed to be a life-threatening hot 45°C (113°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. 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 of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Taking safety measures is non-negotiable; skin and eyes can be swiftly affected if neglected. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Caution! The Sun's UV intensity grows with reflections off sand and water.
