The month of April in the UAE is considered one of the months of the first transition period (spring), characterised by rapid change and variation of atmospheric pressure, thus leading to rapid changes of weather conditions.
The apparent movement of sun continues to move north towards the cancer orbit ,where daytime gradually increases in the northern hemisphere and air temperature increases gradually over most parts of the country while mean air temperatures increase by 3-5°C during this month compared to March.
During this month the effect of Siberian high pressure weakens, while the region is affected by the passage of extensions of low pressure in the upper, and surface from west to east, such as a extension of low pressure of the Red Sea trough or trough from the east, and if these depressions deepen, the amount of clouds increases on some areas with the chances of rainfall.
The humidity decreases slightly during this month in comparison to March, especially during the second half of the month with chances of fog/mist formation during the first half of the month over scattered parts of the country while the frequency of fog/mist decrease during second half of April.
