Go between November and March. That window runs from a November high of 31.0°C (87.8°F) down to a January high of 23.8°C (74.8°F), with January lows of 16.1°C (61.0°F) — the only stretch of the year when you can walk around Dubai Marina at midday without regretting it. Avoid June through September, when highs sit at 39.1°C, 41.7°C, 42.0°C and 39.2°C (102.4°F, 107.1°F, 107.6°F, 102.6°F) and the overnight low in August still reads 31.7°C (89.1°F) — hotter after dark than a summer afternoon in most of Europe.

The climate figures on this page are measured 2025 data for Dubai, which is the arrival point for the large majority of UAE trips. Abu Dhabi runs within about a degree of it; Ras Al Khaimah and the Hajar mountains near Hatta run a little cooler at night; Fujairah on the east coast is more humid year-round.

The best months: December, January, February and March

January is the coolest month of the year at 23.8°C / 16.1°C (74.8°F / 61.0°F). That is the temperature range where the entire city becomes usable — outdoor brunch, the desert, the Corniche, rooftop bars, a full day walking Al Fahidi and the souks — without planning your route around air conditioning. February barely moves: 25.5°C / 18.3°C (77.9°F / 64.9°F).

Those low numbers matter more than the highs. A 16.1°C (61.0°F) January night means a beach dinner is genuinely pleasant and a desert camp gets properly cold once the sun drops — the sand loses heat fast and there is no cloud cover to hold it. This is the one time of year you will actually want a jacket in the Emirates.

March is the last comfortable month and arguably the best single pick: 29.3°C / 19.8°C (84.7°F / 67.6°F) with 2.7mm (0.11in) of rain across 1 day. Warm enough to swim without hesitation, cool enough to spend six hours outside. Sea temperatures have recovered from the winter dip by mid-March, which they have not in January.

December is the wettest month on record here — 23.9mm (0.94in) — but read what that actually is: 23.9mm falling on 2 days. That is roughly 12mm per rainy day, so you get two dramatic, short, heavy downpours and 29 dry days. Dubai's drainage was not built for that concentration, so those two days can flood underpasses and snarl Sheikh Zayed Road for a few hours. The rest of December is 26.6°C / 18.0°C (79.9°F / 64.4°F) and close to perfect.

The months to avoid: June through September

This is not "hot for a beach holiday." It is a heat range where outdoor activity is medically limited.

• June — 39.1°C / 28.1°C (102.4°F / 82.6°F)
• July — 41.7°C / 30.9°C (107.1°F / 87.6°F)
• August — 42.0°C / 31.7°C (107.6°F / 89.1°F)
• September — 39.2°C / 29.2°C (102.6°F / 84.6°F)

The lows are the giveaway. An August low of 31.7°C (89.1°F) is the temperature at roughly 5am, the coolest point of the 24-hour cycle. There is no cool part of the day in August. You cannot go for a morning run and beat the heat, because there is nothing to beat it to.

Add the Gulf humidity — coastal UAE runs 60–90% relative humidity through late summer — and sweat stops evaporating, which is the mechanism your body uses to cool itself. That combination is why hotel pools in July are frequently chilled rather than heated, and why sea temperatures near 35°C (95°F) offer no relief at all. Swimming in bathwater does not cool you down.

Rainfall is not the reason to avoid summer. June recorded 0.2mm (0.01in), and July, August and September recorded 0.0mm across 0 rainy days. It simply does not rain. The heat is the entire problem.

Summer is not a total write-off if you have a specific reason: hotel rates collapse, Dubai Summer Surprises runs indoor retail promotions, and the city's malls, aquariums, indoor ski slope, museums and galleries are all fully climate-controlled. But you are buying an indoor holiday. Budget your outdoor time to before 8am and after 8pm, and even then keep it short.

Shoulder season: late October, November and April

November is the best value month of the year. At 31.0°C / 20.3°C (87.8°F / 68.5°F) with 0.1mm of rain over 0 rainy days, it is only 1.7°C warmer by day than March and cheaper, because the peak-season rate card usually kicks in around the second week of December and runs through February half-term. Daytime in November means genuine beach weather; evenings at 20.3°C (68.5°F) are shirt-sleeve comfortable.

October is a transition. At 34.9°C / 25.9°C (94.8°F / 78.6°F) the first week still feels like the tail of summer, while the last week feels like the start of the good season. If you are booking October, book late October. The month average hides a steep drop — October's high sits 4.3°C below September's and 3.9°C above November's, and most of that fall happens in the second half.

April is the reverse trade, and a worse one. At 35.4°C / 23.2°C (95.7°F / 73.8°F) with 0.0mm of rain over 0 days, it is 6.1°C hotter by day than March. The 23.2°C (73.8°F) nights are still fine, so April works if you shift everything outdoors to evening — desert safaris, dhow cruises, night markets — and keep the middle of the day indoors or in the water. Prices have dropped from the winter peak. May is where this stops working: 37.7°C / 26.4°C (99.9°F / 79.5°F) is functionally summer.

What each season means in practice

Winter (Dec–Feb) — what you'll do and wear. Full days outside. Desert camps, the Palm boardwalk, Global Village, hiking around Hatta, Abu Dhabi's Corniche, Sharjah's heritage district on foot. Pack normally for warm weather, then add one real layer: a January morning at 16.1°C (61.0°F) and a desert evening are both cool enough for a light jacket or sweater, and most visitors are caught out by this. Swimming is fine but the sea is at its coldest of the year; hotels heat their pools in these months for a reason. Two more things: modest dress for mosques and older souks is easier in winter because covering shoulders and knees costs you nothing in comfort, and December's two heavy rain days mean waterproof shoes are worth the space.

Shoulder (Mar, Apr, Oct, Nov) — the split day. March and November need no adaptation at all. April and October need a schedule: outdoors before 10am, indoors or in water from 11am to 4pm, back outdoors after 5pm. Pack light, loose, long-sleeved cotton or linen rather than tank tops — covering skin is cooler than exposing it under this sun, and it solves the modest-dress question at the same time. Sunglasses and a hat are not optional at 35.4°C (95.7°F). Bring a refillable bottle; you will drink far more than you expect.

Summer (May–Sep) — indoor logistics. Your day is structured around air conditioning: mall to metro to taxi to hotel. The Dubai Metro is fully air-conditioned including the platform screens, which makes it dramatically better than taxis or walking. Pack a light cardigan or scarf — indoor spaces are aggressively cooled and the 20°C swing between a mall interior and the street outside is jarring. Loose light-coloured clothing, electrolyte tablets, and sunscreen even for short transitions between buildings. Do not plan a desert safari in July or August; operators run them, but at 41.7°C (107.1°F) it is endurance, not sightseeing.

Month-by-month

• January — 23.8°C / 16.1°C (74.8°F / 61.0°F), 3.4mm over 1 day. Coolest month, best walking weather, peak prices.
• February — 25.5°C / 18.3°C (77.9°F / 64.9°F), 6.6mm over 3 days. Still excellent; 3 light rain days is the most of any month.
• March — 29.3°C / 19.8°C (84.7°F / 67.6°F), 2.7mm over 1 day. The sweet spot: warm sea, comfortable land.
• April — 35.4°C / 23.2°C (95.7°F / 73.8°F), no rain. Hot by day, fine by evening. Shift your schedule.
• May — 37.7°C / 26.4°C (99.9°F / 79.5°F), no rain. Summer in practice.
• June — 39.1°C / 28.1°C (102.4°F / 82.6°F), 0.2mm. Nights no longer cool down.
• July — 41.7°C / 30.9°C (107.1°F / 87.6°F), no rain. Indoors.
• August — 42.0°C / 31.7°C (107.6°F / 89.1°F), no rain. Hottest month, and the 31.7°C low means no relief at any hour.
• September — 39.2°C / 29.2°C (102.6°F / 84.6°F), no rain. Still summer despite the calendar.
• October — 34.9°C / 25.9°C (94.8°F / 78.6°F), 0.2mm. Book the second half, not the first.
• November — 31.0°C / 20.3°C (87.8°F / 68.5°F), 0.1mm. Best value: near-winter comfort, pre-peak prices.
• December — 26.6°C / 18.0°C (79.9°F / 64.4°F), 23.9mm over 2 days. Excellent, with two heavy downpours somewhere in the month.

FAQ

What is the single best month to visit the UAE?

March, at 29.3°C / 19.8°C (84.7°F / 67.6°F). It is the only month that is simultaneously warm enough for comfortable sea swimming and cool enough to spend a full day outdoors, and it falls just after the December–February price peak. If your priority is the lowest heat rather than the best balance, January at 23.8°C / 16.1°C (74.8°F / 61.0°F) is the cooler choice.

How bad is the summer heat, really?

August peaks at 42.0°C (107.6°F) with an overnight low of 31.7°C (89.1°F). The low is the number that matters — it means the air never drops below what most people consider dangerously hot, at any point in the 24-hour cycle. Combined with coastal humidity, sweat does not evaporate efficiently, so your body's cooling system underperforms. Outdoor exertion between roughly 10am and 6pm from June to September should be avoided rather than merely managed.

Does it ever rain in the UAE?

Barely. The measured 2025 total was 37.1mm (1.46in) across 7 rainy days for the entire year. Five months — April, May, July, August and September — recorded 0.0mm. What rain there is arrives in winter and arrives hard: December's 23.9mm (0.94in) fell across just 2 days, which is heavy enough to overwhelm drainage and flood roads for a few hours. Plan for flash flooding on a couple of December days, not for a rainy season.

Is Ramadan a bad time to visit?

It is a different trip, not a worse one, but it moves through the calendar roughly 11 days earlier each year, so check the dates before booking. During daylight hours many restaurants and cafés close or screen off their seating, live music and bars are restricted, and eating, drinking or smoking in public is not done. Hotels continue serving guests, malls and attractions stay open, and evenings after iftar are genuinely lively — night markets, tents and late dining run well past midnight. If your itinerary is heavy on daytime dining and beach clubs, pick different weeks. If you want the country at its most atmospheric and are happy to eat on a local schedule, it is a rewarding time to be there.
