El Niño is back, and this time it could show up in Dubai's winter forecast. The climate pattern — driven by unusually warm surface water in the central and eastern Pacific — is flagged by NOAA as likely to run strong to very strong into early 2027. For the UAE, that doesn't guarantee a washout, but it raises the odds of heavier-than-usual rain between now and spring. Anyone who remembers the chaos when Dubai's streets flooded knows why the city is taking that seriously.
The answer is a project called Tasreef, a stormwater drainage overhaul with a total budget of Dhs30 billion (roughly US$8 billion). Dubai Municipality has just awarded four contracts worth Dhs3 billion as the latest slice of that plan. The new works add about 100 kilometres of drainage channels, some with pipes up to three metres across, covering around 100 square kilometres of the city. Neighbourhoods on the list include Jumeirah, Umm Suqeim, Al Quoz, Al Barsha and Al Wasl — some of the most visited and most photographed parts of Dubai.
When the full programme wraps up in 2033, Dubai expects its drainage capacity to be 700% higher than it is today. That's a long game: the point is less about one wet winter and more about making the emirate resilient to extreme rainfall events as the climate gets less predictable.
El Niño itself is a bit of a wildcard. Scientists track it via sea surface temperatures — sustained warming of at least 0.5°C above average in a defined stretch of the tropical Pacific is the threshold. It has been linked to wetter conditions across parts of the Middle East, but forecasting how much rain actually falls in any given season remains an imperfect science. The UAE, famously, can even make its own rain through cloud seeding, which tells you something about how actively the country engages with its weather.
For travellers, the takeaway is reassurance rather than alarm. A winter trip to Dubai — peak season for Europeans escaping the cold — is very unlikely to be ruined by rain, and even in a wet scenario the city's infrastructure is being built to cope. Beach days at Jumeirah, brunch in Al Barsha and the souks of Al Wasl should carry on as normal. If anything, this is a story about a destination investing so its biggest selling point — reliable winter sunshine with world-class comforts — stays intact. Pack sunglasses; maybe keep a foldable in the bag just in case.
