Heat index

May's mean heat index is appraised at a blisteringly hot 41°C (105.8°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

May is the most humid month, with an average relative humidity of 86%.

Note: An average UV index of 6 in May transforms into this advice:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Caution! The mirror effect of sand and water ups the UV radiation strength.
