Quick answer
Dubai summers, June to September, are very hot — often 40–45°C and humid — but it's the cheapest time to visit and everything indoors runs full air-conditioning. Plan outdoor activities for early morning and after sunset, drink far more water than you think you need, and never leave a child or pet in a parked car.
1How hot Dubai gets in summer
Daytime highs sit around 40–45°C from June to September, and high humidity near the coast makes it feel hotter. The sea is bath-warm, around 33°C. The middle of the day is genuinely draining outdoors, which is why the city's rhythm shifts indoors and to the evening.
2Staying safe in the heat
- Drink water constantly — far more than usual — and go easy on caffeine and alcohol.
- Keep the hot middle of the day for air-conditioned malls and attractions.
- Sunscreen, a hat and sunglasses even for short spells outside.
- Watch children and older travellers for heat exhaustion — dizziness, cramps, nausea.
- Never leave anyone, or a pet, in a parked car; the interior becomes dangerous within minutes.
3Driving and parking a car in summer
A parked car bakes: the cabin can hit extreme temperatures, and the steering wheel and seatbelt buckles burn. When you collect a rental, check the air-conditioning works before you drive off — in a Dubai summer it is a safety item, not a comfort.
- Use a windscreen sunshade and park in shade or covered car parks where you can.
- Let the cabin vent for a minute before getting in; run the AC hard to cool it.
- Check tyre pressures — heat raises them, and blowouts rise in summer.
- Carry water in the car, and never leave children or pets inside, even briefly.
4What to do in a Dubai summer
- Malls and indoor attractions — the aquarium, indoor ski slope, and waterparks that keep you cool.
- The desert and the beach early in the morning or after sunset, when it's bearable.
- Evening dhow cruises and yacht trips once the sun is down.
- Indoor dining, spas and cinemas through the hottest hours.
5The upside: summer deals
Summer is the cheapest time to visit. Hotels discount heavily, Dubai Summer Surprises runs offers across shopping and attractions, and car rental and activities are often cheaper too. If you can work around the heat, your money goes much further.
Book a rental with strong air-conditioning and test it before you drive off — in summer it's the single most important thing to check on the car.
