Latest: Speed limit reduced on UAE motorways as fog returns
It is that time of year again.
After a long hot summer the temperature has finally started to fall a little.
The change also brings frequent fog, which envelopes skyscrapers on the coast as well as sand dunes deep in the desert.
But why, and how, does fog form in the arid climate of the UAE, where the annual rainfall is so low?
The National explains.
What is fog?
Technically, it is a visible aerosol of minuscule water droplets – sort of like a cloud on, or just above, the ground.
It needs certain conditions to form, such as calm winds and a clear atmosphere, which are more common at this time of the year as the seasons change.
There also needs to be dust or sand in the air, because water vapour condenses around the particles – which also explains why the UAE experiences so many foggy episodes.
The country has averaged 132 days of fog formation a year since records began in 2006, with the longest stretch recorded in 2010, when there were 17 days of fog and five days of mist in January.
Fog season does not usually begin until mid-December and runs until the end of March, aided by clear skies and calm conditions.
The sun usually burns it off by 9am, unless it is thick, in which case it has been known to hang around until almost midday.
What kind of fog develops in the UAE?
About 95 per cent of the fog in the UAE is radiation fog, which forms in the early hours as heat absorbed by the Earth's surface during the day radiates into the air, causing water droplets to form. It dissipates in the heat of the sun.
Advection fog is another type seen in the UAE. It forms when warm, moist air passes over a cool surface, creating water vapour.
Both types of fog can result in extremely dangerous driving conditions, such as in February 2018, when a lorry ploughed into a line of traffic in thick fog. In total, 44 vehicles were involved in the pile-up on the E311 road between Abu Dhabi and Dubai.
In 2011, one person died and dozens were injured in a pile-up involving 127 vehicles on the Abu Dhabi-Dubai motorway during thick fog.
Police issue warnings to motorists to inform them of the dangers of driving in fog, reducing the speed limits on motorways if it is particularly dense.

What is Reform?
Reform is a right-wing, populist party led by Nigel Farage, a former MEP who won a seat in the House of Commons last year at his eighth attempt and a prominent figure in the campaign for the UK to leave the European Union.
It was founded in 2018 and originally called the Brexit Party.
Many of its members previously belonged to UKIP or the mainstream Conservatives.
After Brexit took place, the party focused on the reformation of British democracy.
Former Tory deputy chairman Lee Anderson became its first MP after defecting in March 2024.
The party gained support from Elon Musk, and had hoped the tech billionaire would make a £100m donation. However, Mr Musk changed his mind and called for Mr Farage to step down as leader in a row involving the US tycoon's support for far-right figurehead Tommy Robinson who is in prison for contempt of court.

Mane points for safe home colouring
- Natural and grey hair takes colour differently than chemically treated hair
- Taking hair from a dark to a light colour should involve a slow transition through warmer stages of colour
- When choosing a colour (especially a lighter tone), allow for a natural lift of warmth
- Most modern hair colours are technique-based, in that they require a confident hand and taught skills
- If you decide to be brave and go for it, seek professional advice and use a semi-permanent colour

What is the FNC?
The Federal National Council is one of five federal authorities established by the UAE constitution. It held its first session on December 2, 1972, a year to the day after Federation.
It has 40 members, eight of whom are women. The members represent the UAE population through each of the emirates. Abu Dhabi and Dubai have eight members each, Sharjah and Ras al Khaimah six, and Ajman, Fujairah and Umm Al Quwain have four.
They bring Emirati issues to the council for debate and put those concerns to ministers summoned for questioning.
The FNC’s main functions include passing, amending or rejecting federal draft laws, discussing international treaties and agreements, and offering recommendations on general subjects raised during sessions.
Federal draft laws must first pass through the FNC for recommendations when members can amend the laws to suit the needs of citizens. The draft laws are then forwarded to the Cabinet for consideration and approval.
Since 2006, half of the members have been elected by UAE citizens to serve four-year terms and the other half are appointed by the Ruler’s Courts of the seven emirates.
In the 2015 elections, 78 of the 252 candidates were women. Women also represented 48 per cent of all voters and 67 per cent of the voters were under the age of 40.

Other ways to buy used products in the UAE
UAE insurance firm Al Wathba National Insurance Company (AWNIC) last year launched an e-commerce website with a facility enabling users to buy car wrecks.
Bidders and potential buyers register on the online salvage car auction portal to view vehicles, review condition reports, or arrange physical surveys, and then start bidding for motors they plan to restore or harvest for parts.
Physical salvage car auctions are a common method for insurers around the world to move on heavily damaged vehicles, but AWNIC is one of the few UAE insurers to offer such services online.
For cars and less sizeable items such as bicycles and furniture, Dubizzle is arguably the best-known marketplace for pre-loved.
Founded in 2005, in recent years it has been joined by a plethora of Facebook community pages for shifting used goods, including Abu Dhabi Marketplace, Flea Market UAE and Arabian Ranches Souq Market while sites such as The Luxury Closet and Riot deal largely in second-hand fashion.
At the high-end of the pre-used spectrum, resellers such as Timepiece360.ae, WatchBox Middle East and Watches Market Dubai deal in authenticated second-hand luxury timepieces from brands such as Rolex, Hublot and Tag Heuer, with a warranty.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.
