Video: UAE to experience longest day of the year this month

Abu Dhabi - During this time, air temperatures will increase over most areas of the country, experts said.

The UAE will experience the longest day of the year on June 21 and temperatures will increase gradually throughout the month over most parts of the country, according to weather forecasters.

In its climate report for the month of June, released on Tuesday, the National Centre of Meteorology (NCM) said the summer solstice occurs when the sun’s rays are directly over the tropic of cancer (23.37 degrees North). This will occur on June 21 this year, thereby making it the longest day the country will experience this year.

During this time, especially the last third of the month, air temperatures will increase over most areas of the country.

The report said that, as summer begins, the mean temperatures will increase approximately 2-3°C during June, as compared to month of May.

”The effect of the Siberian high pressure system over the country is weakening and retreating during this month. The thermal lows will affect the area, where the extension of Indian monsoon depression affect the country from east over most periods of this month,” the NCM said in the report.

“Clouds will develop at times over some areas with chances of formation of cumuliform clouds over eastern mountains during afternoon hours, leading to rainy weather at times.“

The forecasters said humidity would decrease slightly during this month, compared to May — particularly during the second half. They added that chances of formation of fog or mist will also be less, especially in the second half of the month.
