Autumn starts on Sunday: UAE weather to change?

Astronomers calculated that this year’s autumnal equinox will fall on September 23, marking the first day of autumn

Dams and wadis get their share of rain during the winter months in the UAE.

Dubai: The UAE has come out of its notoriously hot summer season, and during the last few weeks, has gradually become cooler with maximum temperatures dropping to 35C.

But how likely is the UAE weather expected to change once autumnal equinox starts?

The word “equinox” comes from the Latin word equi, meaning “equal” and nox, meaning “night”. It marks the two events of the year, in March and September, when the sun is exactly above the equator and the day and night are of equal length.

Ebrahim Al Jarwan, General Supervisor at Sharjah Planetarium, said that according to astronomical calculations, the autumnal equinox will fall on Sunday, September 23 – it always takes place from September 22 to September 24.

Al Jarwan explained that at the beginning of the autumnal equinox, the number of hours at night is equal to daylight hours.

“But then the hours in the day start to reduce while the hours at night become longer, until we reach the shortest day of the year on December 22,” he said.

Even though autumn will officially start, it won’t be until the beginning of October before residents will notice a change in temperature. 

The Abu Dhabi-based National Centre of Meteorology (NCM) said that over the next few days, the weather will remain fair in general with some low clouds in the eastern coast.
