Weather in May
Temperature
The average high-temperature during May registers at a still hot 32.7°C (90.9°F), maintaining a close resemblance to the previous month. In the month of May, the nighttime temperature dips to a steady average of 22.7°C (72.9°F).Heat index
The heat index in May is computed to be a blisteringly hot 43°C (109.4°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.The standards for the heat index are set for locations in shade and under light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 relevant to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

In May, the average daily maximum UV index is 7. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: The daily high UV index of 7 in May translates into this advice:
Shun overexposure. Protection from sun ravages is indispensable. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
