Weather in May
Temperature
A minor adjustment in Sayfaf's average high-temperature is noted with the start of May, touching a torrid 35.4°C (95.7°F) from April's 33.8°C (92.8°F). During May nights, Sayfaf witnesses a consistent average temperature of 30°C (86°F).Heat index
May's heat index is computed to be a life-threatening hot 45°C (113°F). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.Heat index determinations are made taking into account the shade and light air movements. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

The average relative humidity in May is 58%.Rainfall
In Sayfaf, during May, the rain falls for 2.4 days and regularly aggregates up to 4mm (0.16") of precipitation. Throughout the year, there are 45.7 rainfall days, and 86mm (3.39") of precipitation is accumulated.Daylight

Sunshine
With an average of 12.2h of sunshine, May has the most sunshine of the year.UV index
The months with the highest UV index are April through October, with an average maximum UV index of 8. A UV Index estimate of 8 to 10 represents a very high health hazard from exposure to the Sun's UV rays for the ordinary person.Note: An average UV index of 8 in May transforms into this advice:
Never be careless. Unprotected skin and eyes can be harmed swiftly. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
