UAE residents, there’s light at the end of the summer tunnel. Meteorological autumn officially arrived on September 1, marking the start of the three-month period when temperatures are expected to gradually ease across the country.
But don’t expect winter-like weather just yet. September can still be hot, the difference is that the intense summer heat should slowly begin to lose its grip.
According to Ibrahim Al Jarwan, Chairman of the Board of Directors of the Emirates Astronomical Society and a member of the Arab Union for Astronomy and Space Sciences, meteorological autumn runs from September 1 to November 30 in the Northern Hemisphere.
So, when does autumn actually begin?
Here’s where it gets slightly confusing. September 1 marks the beginning of meteorological autumn, which is based on calendar months and typical temperature patterns used for climate reporting.
Astronomical autumn arrives later. In the UAE, the autumnal equinox will take place on September 23, at around 4.05am (UAE time).
That’s when the Sun crosses the celestial equator from north to south, officially marking the astronomical start of autumn in the Northern Hemisphere.
When will the UAE start feeling cooler?
The good news is that September should bring a noticeable change.
After months when daytime temperatures frequently reached 42°C or higher, most September days are expected to see highs below 39°C, while overnight temperatures should dip below 27°C.
The cooling trend becomes more noticeable in October, when daytime temperatures are expected to fall below 35°C on most days and nighttime lows could drop below 22°C.
By November, things should feel considerably more comfortable, with daytime temperatures generally below 30°C and nights dropping 18°C below on most days.
By the end of meteorological autumn, temperatures could fall to around 26°C or lower during the day and 15°C at night across much of the UAE.
So while residents shouldn’t pack away the air conditioner just yet, the country’s long, scorching summer is gradually giving way to cooler months.
And for anyone counting down to outdoor season, September is the first hint that better weather is on the way.
