Dubai is known for its hot, sunny weather throughout much of the year. However, some months bring more extreme heat than others. July and August are typically the hottest months in Dubai, with average high temperatures around 106°F (41°C).

Which month is hottest in Dubai?

Why Summer is the Hottest Time in Dubai

Several factors contribute to Dubai’s summer heat:

  • Location – Dubai is a desert climate in the Arabian Peninsula, an area known for extremely hot summers.
  • Humidity – High humidity levels from the nearby Persian Gulf make the heat feel oppressive. Humidity levels average 60-80% in summer.
  • Long daylight hours – Summer days are around 13 hours long, meaning more daytime for temperatures to rise.

Additionally, the lack of rain in Dubai during summer months means there is little relief from the unrelenting heat.

Daily Temperature Range

While summer days bring sweltering temperatures, things do cool off somewhat in the evenings. Here is an overview of the daily summer temperature range in Dubai:

  • Early Morning (6 AM) – 84-90°F (29-32°C)
  • Afternoon (3 PM) – 104-113°F (40-45°C)
  • Evening (9 PM) – 90-95°F (32-35°C)

So even at night, Dubai remains very warm in the summer months. Early morning or late evening are the best times to beat the extreme heat if spending time outdoors.

Month-by-Month Breakdown of Dubai’s Hottest Weather

Below we’ll explore Dubai’s climate month-by-month focusing on the hottest part of the year:


  • Average High: 100°F (38°C)
  • Average Low: 81°F (27°C)

May kicks off the summer heat in Dubai. While highs average right around 100°F, it can reach as hot at 113°F (45°C) on the hottest days. With very little rain, relief from heat is slim.


  • Average High: 104°F (40°C)
  • Average Low: 84°F (29°C)

June is when temperatures really begin to soar in Dubai. The city sees the year’s longest days in June, meaning more daytime hours for the mercury to rise. Overnight lows only drop to 84°F, offering little respite.


  • Average High: 106°F (41°C)
  • Average Low: 86°F (30°C)

July ties for the hottest month in Dubai, with average daily highs peaking at 106°F. With nearly zero rainfall, there is no break from sweltering temperatures that can reach as high as 113°F (45°C) or more on the hottest summer days.


  • Average High: 106°F (41°C)
  • Average Low: 86°F (30°C)

August ties July for the hottest month in Dubai. Average high and low temperatures are nearly identical to those seen in July, meaning days with highs exceeding 113°F (45°C) are common. The warm Arabian Sea keeps overnight lows very balmy as well.

As you can see, late July and August are clearly the most consistently hot months in Dubai when looking at climate data. However, May through September are all considered very hot summer months in the city.

Beating the Heat in Dubai

If visiting Dubai during the torrid summer months, there are some ways to minimize your exposure to the excessive heat:

  • Spend more time indoors – Malls, hotels, attractions, and other air-conditioned spaces provide a welcome escape.
  • Limit outdoor time to mornings/evenings – The intense midday sun should be avoided whenever possible.
  • Stay hydrated – Drink plenty of water since dehydration comes easily in Dubai’s arid climate.
  • Choose breathable clothing – Lightweight, loose-fitting clothes in breathable fabrics will help you keep cool.
  • Don’t overlook sun protection – Use sunscreen, hats, sunglasses and seek shade even during morning/evening hours.

Following these tips can help you better enjoy Dubai, even during the hottest summer months when temperatures are extreme.

Long-Term Climate Trends

As the climate changes globally, Dubai has experienced an increasing number of extremely hot summer days over the past several decades. If global warming projections hold true, the city could see summer temperatures rise an average of 9°F (5°C) by the end of century according to some estimates. This would push many summer days into the lethal range of 122°F (50°C) or hotter.

Only time will tell how climate change will impact Dubai’s already extremely hot summertime temperatures in the long run. But the outlook suggests even more unprecedented heat ahead in the hottest months of July and August.

Key Takeaways

  • July and August tie as the hottest months in Dubai with average highs of 106°F (41°C)
  • Summer heat is driven by long daylight hours, intense sunlight, high humidity from the Persian Gulf and lack of rainfall
  • May – September all experience extreme heat and little precipitation
  • Avoiding midday sun, staying hydrated and spending more time in A/C spaces can provide some heat relief
  • Climate change may raise Dubai’s summer temperatures by up to 9°F (5°C) in the coming decades


With average highs of 106°F (41°C) in both July and August, it’s clear these two months share the title for hottest in Dubai. But the entire summer from May to September sees unrelenting heat and little if any rainfall for the desert city. As temperatures have slowly climbed in Dubai due to global warming over recent decades, it’s possible we could see even hotter summers in the coming years.

Visitors would be wise to avoid the midday sun by sticking to well air-conditioned indoor spaces as much as possible during their stay to beat the extreme heat. And knowing to expect unrelenting highs over 105°F for months on end, one can properly prepare with breathable clothing and plenty of sun protection before traveling to Dubai in the summer.

By better understanding Dubai’s hottest weather patterns, you can now plan summer trips accordingly and employ the necessary heat precautions if you decide to visit during July or August to experience the peak summertime conditions the city has to offer.
