Temperature

With the start of May, Al Khabr measures an average high-temperature of a still hot 32.6°C (90.7°F), not significantly differing from April's 30.1°C (86.2°F). Al Khabr records an average low of 25.5°C (77.9°F) throughout the nights in May.

Heat index

The heat index value during May is appraised at a very hot 38°C (100.4°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
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. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. 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. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. To best shield against UV radiation, choose sun-safe garments and dependable sunglasses.
