May weather forecast
Sur, Oman

May continues the summer streak with soaring temperatures but manages to prevent a surge in humidity levels. The warmth lingers throughout the day due to extended sunshine hours and a corresponding decrease in precipitation. Despite the torrid conditions, the city of Sur retains its charm under the sweltering Omani sun. The forthcoming month, June extends the high temperature but with stabilized weather conditions. The highest temperature in May can go up to 41.3°C (106.3°F), testament to the heated conditions of Sur during this time.

Temperature

Observing a slight rise in May, the average high-temperature in Sur shifts from April's torrid 36.5°C (97.7°F) to a blistering 41.3°C (106.3°F). During May, Sur experiences an average low-temperature of 29.8°C (85.6°F) at night.

Heat index

During May, the heat index is calculated to be a life-threatening hot 62°C (143.6°F). Warning: These weather conditions are viewed as overly hazardous, with approaching heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

May is the least humid month, with an average relative humidity of 53%.

Rainfall

In Sur, during May, the rain falls for 0.3 days and regularly aggregates up to 2mm (0.08") of precipitation. Throughout the year, there are 13 rainfall days, and 82mm (3.23") of precipitation is accumulated.

UV index

April through August, with an average maximum UV index of 12, are months with the highest UV index. A UV Index estimate of 11, and higher, represents an excessive health risk from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: In May, the maximum UV index of 12 suggests these recommendations:
Take every essential safety procedure. Individuals with fair skin could sustain burns in less than 5 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
