Temperature

The advent of May denotes an average high-temperature of a still hot 32.5°C (90.5°F), subtly different from April's 32.3°C (90.1°F). During the May nights, an average temperature of 24.8°C (76.6°F) is observed.

Heat index

May's heat index is evaluated at a blazing hot 46°C (114.8°F). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
