Abu dhabi: The National Centre of Meteorology (NCM) announced that April marks the beginning of the first transitional season, characterized by rapid changes in atmospheric pressure, resulting in swiftly altering weather conditions.
According to Emirates News Agency, the NCM stated that the sun's apparent movement towards the Tropic of Cancer will lead to a gradual increase in daylight hours across the Northern Hemisphere. This shift is expected to cause a steady rise in temperatures across most parts of the country, with mean temperatures anticipated to increase by 3 to 5°C during April compared to March.
The weakening influence of the Siberian high-pressure system will allow low-pressure systems to affect the region. These systems, moving from west to east, include extensions of the Red Sea trough and systems approaching from the east. When these depressions deepen, cloud cover is likely to increase, with chances of rainfall over some areas.
Humidity levels are expected to decrease slightly compared to March, particularly during the second half of April. However, fog and mist formation remains possible over scattered areas, especially in the first half of the month, with a gradual decline in frequency later.
Climatic statistics indicate that the average temperature in April ranges between 25°C and 30°C, with maximum temperatures averaging between 32°C and 37°C, and minimum temperatures between 20°C and 23°C. The highest recorded temperature for the month was 46.9°C in Al Ruwais in 2012, while the lowest was 5.0°C in Jebel Jais in 2013.
Wind speeds average around 13 km/h, with the highest recorded wind speed reaching 121.3 km/h in Jebel Hafeet in 2013. The highest wind gust recorded was 137 km/h at Al Ain Airport in 2003.
The average relative humidity is approximately 43 percent, with maximum levels ranging between 62 percent and 82 percent, and minimum levels from 17 percent to 28 percent. In 2015, the highest frequency of fog was recorded with 11 foggy days and four misty days.
In terms of rainfall, the highest amount recorded in April was 260.3 mm in Khatam Al Shaklah in Al Ain in 2024.
