Heat index

The heat index value for May is evaluated at a life-threatening hot 47°C (116.6°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

The average relative humidity in May is 76%.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
