Weather in May
Temperature
The transition into May is marked with an average high-temperature of a still hot 31.2°C (88.2°F), showing an insignificant shift from April's 30.6°C (87.1°F). An average low-temperature of 23.3°C (73.9°F) is common during the nights of May.Heat index
The heat index value for May is computed to be an extremely hot 41°C (105.8°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Sunshine
In May, the average sunshine is 9.1h.UV index
February, April through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for ordinary individuals.Note: The daily high UV index of 7 in May translates into this advice:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
