Heat index

The heat index in May is evaluated at an extremely hot 44°C (111.2°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Note that heat index values are valued for light wind and location in the shade. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. 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. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Note: The daily high UV index of 7 in May translates into this advice:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Be alert! The reflection of water and sand augments UV radiation intensity.
