Dubai in December: 26°C / 79°F afternoons, 17°C / 63°F nights, two holidays and the first evenings that ask for a sweater.
Pack for the evenings. NOAA's figures for Dubai International Airport give December 26.5°C by day and 17.4°C at night across 1991–2020, with about 10mm of rain over one or two days, and the National Center of Meteorology says the cooling steepens after 23 December, with fog and mist on humid mornings. Visit Dubai is specific: "Between December and February, it can sometimes get a little chilly in the evenings. Expect lows of around 14°C," and "a light sweater or a similar item of clothing should be enough." The month opens with the Eid Al Etihad celebrations and their fireworks and closes with New Year's Eve in Downtown, where last year's roads began closing at 4pm. Pack a cardigan for the city, something warmer for a night in the desert, and flat shoes for the long walk in.
December in Dubai is warm enough to eat outside and cool enough to want a sleeve by nine. Pack one sweater and one plan for reaching the fountain on foot.

Visit Dubai says December evenings "can sometimes get a little chilly" and that "a light sweater or a similar item of clothing should be enough". A cream V-neck cardigan is that sweater: over the shirt dress at 17.4°C after dark, over the silk shell in a cold mall, and folded into the bag at noon.

Emaar's free public viewing areas along Sheikh Mohammed bin Rashid Boulevard were first come, first served last year, which means hours on your feet from late afternoon to midnight. A long-sleeve shirt dress covers you in a family crowd and stays comfortable that long, and black takes the cream cardigan over it.

December is the month to eat outside at lunch, when the airport averages 26.5°C. A silk shell is cool in the sun and goes under the cardigan once you move indoors, and pistachio is the one soft colour against the black, cream and plum.

A daytime trouser for the souks, the Creek and the festive market that Visit Dubai points to at Madinat Jumeirah. Wide linen covers your legs, stays cool at 26.5°C, and pale blue sits with the pistachio and the ivory scarf.

For the last New Year's Eve, Emaar warned that road closures would begin "as early as 4 PM" and pointed visitors to the Metro, so the night starts with a long walk and ends with a longer one. Flat leather loafers handle both, and they look right with the black dress at midnight.

Visit Dubai warns that in the desert "temperatures can drop sharply once evening arrives" and tells overnight campers to bring plenty of warmer clothing. A heavy oversized overshirt goes over the cardigan by a campfire, and dark plum hides the dust of the dunes.

The National Center of Meteorology says humid December mornings bring fog and mist, and an ivory scarf takes the damp off your neck before it clears. It also covers your hair for a visit to Jumeirah Mosque, whose dress code asks women to cover arms, legs and hair.

Small enough for a crowd from 4pm to midnight, with room for a phone, a card and the scarf. Camel suede sits with the black dress and the cream knit, and a chain strap keeps it on your shoulder when your hands are full.
Pistachio silk shell · pale blue linen trousers · ivory scarf · black loafers · camel bag. A foggy start that clears by mid-morning, lunch outdoors in Jumeirah.
Black shirt dress · cream cardigan · black loafers · camel bag. New Year's Eve in the Downtown public viewing areas, walking in from the Metro before the roads close, or the Eid Al Etihad fireworks at the start of the month.
A suggested look — black long-sleeve shirt dress, cream v-neck cardigan, black penny loafers, ivory fringed scarf.
Warm days and the first cool evenings. NOAA's figures for Dubai International Airport give an average December high of 26.5°C and a low of 17.4°C across 1991–2020, with about 10mm of rain over one or two days. The National Center of Meteorology says December's highs and lows fall 3 to 6 degrees below November's, that cooling steepens after 23 December, and that humid mornings bring fog and mist; rain is occasional but can be intense. Visit Dubai puts December's average at 24°C. Sunset moves from about 5:28pm on 1 December to 5:39pm on the 31st.
A cream V-neck cardigan, a black long-sleeve shirt dress, a pistachio silk shell, pale blue wide linen trousers, black penny loafers, a dark plum overshirt, an ivory scarf and a small camel bag. That covers a sunny lunch, a mall, a mosque visit, a desert evening and New Year's Eve on foot. Add a swimsuit for the beach, where Visit Dubai says swimwear belongs.
Flat shoes, a long sleeve and a light layer. For the 2025–26 edition, Emaar opened free public viewing areas along Sheikh Mohammed bin Rashid Boulevard on a first-come, first-served basis, allowed food and non-alcoholic drinks, started celebrations at 5pm and closed roads from as early as 4pm, pointing visitors to the Burj Khalifa/Dubai Mall Metro station. The ticketed Burj Park banned glass, aerosols, tripods, noise-makers and flags over 30 by 30 cm. The 2026–27 details were not published by late September. Expect a 17°C night after a long afternoon standing.
Early December, for the fireworks without the school holidays. The city's retail calendar sets the Eid Al Etihad celebrations from 30 November to 3 December; the public holiday itself is announced each year, and in 2025 it fell on 1 and 2 December. Dubai's private schools break from 14 December to 4 January, and the National Center of Meteorology says cooling steepens after the 23rd. The Dubai Shopping Festival's 2026–27 dates were not announced by late September; the last edition ran from 5 December to 11 January.
January is about two degrees cooler and a little wetter. NOAA's airport figures give January 24.3°C by day and 15.5°C at night, against December's 26.5°C and 17.4°C, with about 12mm of rain. Visit Dubai calls January the coldest month, at about 24°C by day and 14°C at night. January also brings the Dubai Marathon on 17 January and the Shamal winds, which our January guide covers.
A light layer in the evening, and pieces made in the UAE. The Giving Movement, a Dubai athleisure label launched in April 2020, says everything it makes is "sourced locally in the UAE, from supply to production". Emirati dress, the kandura for men and the abaya with a sheila for women, is what Jumeirah Mosque lends to visitors who arrive without covering. For the Eid Al Etihad celebrations, the city's calendar describes "a period of patriotic pride".
