Heat index

In May, the average heat index is estimated at a blistering 44°C (111.2°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in 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.

UV index

Note: In May, the maximum UV index of 7 translates into these guidelines:
Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
