Temperature

During May, Babel records an average high-temperature of a still warm 29.5°C (85.1°F), marking a slight divergence from April's 29.7°C (85.5°F). During May, the temperature is averaged to a low of 23.3°C (73.9°F) at night.

Heat index

The average heat index in May is evaluated at a very hot 38°C (100.4°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Note: In May, the maximum UV index of 6 suggests this advice:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
