NCM forecasts unstable weather across UAE from Saturday until April 10

The National Centre of Meteorology (NCM) on Friday has forecast unstable weather conditions across the UAE from Saturday until April 10, accompanied by chances of rainfall and increased wind activity.

The centre said in a statement today that the weather from Saturday night and Sunday will be partly cloudy to cloudy at times, with a chance of light rain over the islands and some northern areas.

On Monday, Tuesday and during Wednesday daytime, the weather will be clear to partly cloudy and at times dusty due to active to strong northwesterly winds, causing blowing dust and a drop in temperatures, while the sea will be rough to very rough at times.

The weather is expected to become unstable again from Wednesday night until Friday morning, with partly cloudy to cloudy conditions at times and a chance of light to moderate rainfall over scattered areas of the country at intermittent periods.

The NCM also said April is part of the first transitional season (spring), marked by rapid changes and variability in atmospheric pressure, leading to fast-changing weather conditions.

The NCM said in a statement that the sun continues its apparent movement northwards towards the Tropic of Cancer, resulting in a gradual increase in daylight hours across the Northern Hemisphere, alongside a steady rise in temperatures across most parts of the country. Mean temperatures are expected to increase by 3 to 5°C during April compared to March.

During this month, the influence of the Siberian high-pressure system weakens, while the region is affected by extensions of low-pressure systems in the upper and surface layers moving from west to east, including extensions of the Red Sea trough or systems approaching from the east. When these depressions deepen, cloud cover increases over some areas, with chances of rainfall.

Humidity is expected to decrease slightly compared to March, especially during the second half of the month. However, there remains a chance of fog and mist formation over scattered areas, particularly during the first half of April, with a gradual decline in frequency in the latter half.

According to climatic statistics, the average temperature during April ranges between 25°C and 30°C, with average maximum temperatures between 32°C and 37°C, and minimum temperatures between 20°C and 23°C. The highest temperature recorded during the month was 46.9°C in Al Ruwais in 2012, while the lowest was 5.0°C in Jebel Jais in 2013.

The average wind speed is around 13 km/h, with the highest recorded wind speed reaching 121.3 km/h in Jebel Hafeet in 2013, and the highest wind gust recorded at 137 km/h at Al Ain Airport in 2003.

The average relative humidity is around 43 percent, with maximum levels ranging between 62 percent and 82 percent, and minimum levels between 17 percent and 28 percent. The highest frequency of fog was recorded in 2015, with 11 foggy days and four misty days.

Regarding rainfall, the highest amount recorded in April was 260.3 mm in Khatam Al Shaklah in Al Ain in 2024
