The National Centre of Meteorology (NCM) said May is considered one of the months of the first transition period (spring) between winter and summer.
The authority explained that the month is marked by a gradual northward shift of the apparent movement of the sun, leading to longer daytime hours and a steady rise in temperatures across the UAE, a WAM report said.

”During this month the apparent movement of sun continue to move north of the equator where daytime gradually increases in the northern hemisphere which lead to a gradual increase of air temperature over most parts of the country during this month,” said the NCM in its May climate summary.
Changing weather systems
The NCM noted that the Siberian high-pressure system weakens during May, while weather depressions influence the region from the east and west. When combined with extensions of westerly upper-air troughs, cloud cover increases and the chances of rainfall rise.
Humidity levels are expected to decline slightly compared to April, particularly in the second half of the month. The agency also said fog and mist formation remains possible, especially during the first half over scattered areas, with occurrences decreasing later in May.
Climate statistics
According to the NCM, mean air temperatures range between 30.6°C and 33.6°C, while mean maximum temperatures range from 37.3°C to 40.7°C. Mean minimum temperatures vary between 24.3°C and 26.8°C.
The highest recorded temperature for May reached 51.6°C in Sweihan in 2025, while the lowest minimum temperature fell to 9.0°C at Jabal Jais in 2005.
Mean wind speed stands at 13 km/hr, with the strongest recorded winds reaching 117.2 km/hr at Jabal Mebreh in 2010. Relative humidity averages 39 per cent, with maximum values ranging between 54 per cent and 82 per cent, and minimum levels between 14 per cent and 22 per cent.
In May 2021, the month recorded the highest frequency of fog with four fog events and 10 misty days. The highest rainfall recorded for May was 134.4 mm in Al Fali in 1981.
Authorities also advised residents to take precautions during rising daytime temperatures, stay hydrated, and monitor official forecasts regularly as seasonal conditions continue to shift across the UAE during May month period overall.
