UAE: Gradual Increase in Temperatures Across Most Regions in May – UAE


The National Center of Meteorology has reported that May will witness a gradual increase in temperatures across most regions of the country.

The center noted that May is one of the months of the first transitional period (spring) between winter and summer. During this period, the sun’s movement shifts visibly towards the north from the equator, resulting in gradually longer days in the northern hemisphere. This leads to a gradual rise in temperatures across most regions of the country during this month.

The National Center of Meteorology further stated that the influence of the Siberian high pressure system on the country weakens and recedes during this month, while low-pressure systems affect the region. A low-pressure system extends from the west or the east, accompanied by the extension of upper-level low-pressure systems moving from west to east, increasing cloud cover in some areas with a chance of rainfall.

Regarding humidity in May, the National Center stated that humidity levels decrease slightly compared to April, especially in the latter half of the month. Fog and mist formation remain possible in scattered areas, especially during the first half of the month, with occurrences decreasing in the latter half.
