London City always gets hit by fog, Leeds by high winds, New York / Chicago / Boston by snow, Heathrow by a multitude of things, CDG by strikes, Istanbul by weather.
Fly via HK in the summer and you may get hit by Cyclones along with Taipei and other cities in the region.
Anywhere can get hit. I’ve had numerous people affected this year all over the world with incidents caused by weather and other issues. To have a pop at Dubai specifically seems unnecessary. One of those things that can happen and area as others have posted seems to be having unusual weather patterns.
