Abu Dhabi and Dubai are about an hour and a half apart by motorway, and many people assume their weather is the same. Broadly speaking, it is, but there are details worth knowing, especially if you're travelling in winter or planning a trip into the desert.

Abu Dhabi is often seen as a "quiet Dubai": fewer skyscrapers per square metre, more museums and beaches without the crowds. Tourists choosing between the two cities usually compare hotels and attractions, and assume the weather is the same: after all, they're neighbours on the same shore of the Persian Gulf.

That's almost true, but the emirate of Abu Dhabi covers most of the country's territory, and a trip there can take in the Liwa desert, the Al Ain oasis and the hottest places in the UAE.

When to Go: The Seasons Month by Month

The high season in Abu Dhabi, as in the rest of the Emirates, runs from November to March. Below are average daytime and night-time temperatures in the capital, along with sea temperatures.

  • January — 24°C by day, 14°C at night, with the sea at around 22°C. The coolest month. Too cool for the beach, but ideal for sightseeing.

  • February — 26°C by day, with the sea at around 21°C, the coldest water of the year. You can swim, but not everyone will find it comfortable.

  • March — 30°C by day, 18°C at night, with the sea at 22°C. Spring: it's already hot during the day, but the evenings are pleasant.

  • April — 35°C by day, with the sea at 25°C. The last month when you can spend the whole day outdoors, although the heat is already noticeable.

  • May to September — 40–43°C by day, 25–30°C at night, with the sea at 29–33°C. The water is as warm as a bath and barely refreshing. Life moves into shopping centres and indoor theme parks.

  • October — 37°C by day, with the sea at 31°C. The heat eases slowly, but by the end of the month the season begins.

  • November — 31°C by day, 20°C at night, with the sea at 28°C. Arguably the best month: the sea is still warm after the summer, and the daytime heat is already bearable.

  • December — 26°C by day, 16°C at night, with the sea at 25°C. The peak of the tourist season, and the time of the most interesting events.

There's almost no rain in Abu Dhabi: around 50–55 mm falls over the year, and almost all of it in winter.

Abu Dhabi and Dubai: What's the Difference?

If you compare average climate data, the two cities are like twins. The difference lies in the details.

In winter, Abu Dhabi is slightly cooler. Nights in January and December are about 1°C colder here than in Dubai: 14°C versus 15°C in January. The sea is also a degree cooler in winter: 21°C versus 22°C in February. For swimming, the difference is small but noticeable, especially for those heading to the beach in the depths of winter.

In summer, Abu Dhabi is slightly hotter during the day. In August the average maximum here is 43°C, compared with 42°C in Dubai. Summer nights, on the other hand, are warmer in Dubai: 32°C versus 30°C. The difference is hard to feel: in August, nobody in either city goes outside during the day by choice.

Abu Dhabi is even drier. Around 50–55 mm of rain falls here a year, compared with about 80–90 mm in Dubai. Rain is rare in the Emirates anyway, but if you're worried about a ruined winter holiday, the capital gives you slightly better odds.

From September to March, the Emirates get fog, most often in December and January. According to long-term data, at Abu Dhabi airport, which has more fog than any other airport in the country, it's recorded on about 24 days a year on average, and in some years up to 50.

Fog forms between evening and late morning, most often at dawn on still days, when the ground has cooled overnight and chills the air above it. It usually doesn't last long, about an hour, but in the winter months thick fog can linger until midday. It's particularly dangerous on the Abu Dhabi–Dubai motorway: if you're heading to the neighbouring emirate early in the morning, it's better to set off a little later.

The Emirate of Abu Dhabi: From the Sea to the Hottest Places in the Country

Abu Dhabi's main climatic difference lies not in the city but in the emirate. Unlike compact Dubai, it stretches deep into the Arabian Peninsula, and the weather there is quite different.

Al Ain is an oasis city near the border with Oman, about an hour and a half to two hours' drive from the capital. It lies far from the sea, so it's drier and hotter here: in summer, the average maximum reaches 45°C. In winter, though, Al Ain is pleasant, and nights in the desert can be cool.

Near Al Ain is Sweihan, one of the hottest places in the country. Thermometers here recorded 51.8°C on June 6, 2021, and again on August 1, 2025.

Liwa is an oasis in the south of the emirate, on the edge of the Rub' al Khali, one of the largest sand deserts in the world. People come here to see the giant dunes. It's only worth going to Liwa in season: in summer, being in the desert is physically dangerous, while in winter it's warm by day and cold at night.

What to Do in Season

From November to March, Abu Dhabi offers more than just the beach.

  • Sheikh Zayed Grand Mosque — one of the largest mosques in the world, with free entry. The best time to visit is around sunset, when the white marble changes colour.

  • Saadiyat Island — home to the Louvre Abu Dhabi and one of the city's best white-sand beaches.

  • Yas Island — with Ferrari World, Warner Bros. World and SeaWorld theme parks. They're all indoors, so they're open all year round, including in summer.

  • The Abu Dhabi Grand Prix — the final round of the Formula 1 season at the Yas Marina circuit. In 2026, it takes place from December 3 to 6. If you're not going to the race, bear in mind that hotel prices in the city are noticeably higher on those days.

How to Get There and What You Need to Know

Etihad, Aeroflot and Pobeda operate direct flights from Moscow to Abu Dhabi. In 2026, the situation became complicated several times: airspace was closed and scheduled flights to the UAE were suspended. Before you travel, keep an eye on the news and check schedules with the airlines.

Russians don't need a visa: on arrival, you'll get a free 90-day stamp in your passport. Your passport must be valid for at least six months from the date of entry, and children need their own passport. Russian bank cards don't work in the UAE, so bring cash in dollars or euros, or a card from a foreign bank.

How to Choose When to Go

For a beach holiday, November and March are best. In November the sea is still warm after the summer, while in March the air has already warmed up but the water hasn't yet turned hot.

For sightseeing and the desert, go in December, January or February. Daytime temperatures are around 24–26°C, so you can travel to Al Ain and Liwa and take long walks around the city. But if the sea is what matters most, it may feel cool in the depths of winter.

In summer, Abu Dhabi is only really suitable for a hotel holiday by the pool and visits to the indoor theme parks. On the other hand, hotel prices are noticeably lower in the off-season, which for some people is a good enough reason.
