Dubai in August is searingly hot, with average daytime highs of 42°C and humidity that pushes the feels-like temperature past 50°C. This is the city’s hottest month, with relentless sunshine and only rare, brief downpours that do little to cool things down.
What is the typical temperature range in Dubai during August?
The mercury regularly climbs to 45°C or higher in the afternoons, while overnight lows rarely drop below 30°C. The Persian Gulf waters reach around 33°C – bath-warm for swimming but not refreshing. Combined with humidity often above 60%, August heat can feel oppressive, especially for visitors unused to this climate.
Is it worth going to Dubai in August?
It depends on your tolerance for extreme heat. Many tourists avoid August because outdoor sightseeing is uncomfortable between late morning and early evening. However, hotels, shopping malls and indoor attractions are heavily air-conditioned, so it can still be a viable trip if you plan around the heat. Those considering autumn should check how hot is Dubai in October, when highs drop to around 37°C. For comparison, how hot is Dubai in July is similarly fierce, while how hot is Dubai in September eases slightly to 39–40°C. By November, highs are a far more pleasant 31°C.
Can you sunbathe in Dubai in August?
Yes, but only for short periods before 10am or after 4pm. The sun is extremely intense and heatstroke is a real risk. Use high-factor sunscreen, stay hydrated and take breaks indoors.
How does August compare to July?
July and August are virtually identical – both average around 42°C highs. August sees slightly less sunshine (still 11 hours a day) and marginally more humidity, so the felt heat is about the same.
What about September temperatures?
September remains very hot, with highs around 39–40°C and humidity still high. It’s only from late September that a gradual drop begins, making evenings slightly more bearable. For full details, see our Dubai weather guide.
