What is the hottest month in Abu Dhabi?

Abu Dhabi, the capital and second largest city in the United Arab Emirates, is known for its hot desert climate with long, extremely hot summers. The hottest month in Abu Dhabi is August, with average high temperatures over 104°F (40°C) and average lows remaining a balmy 88°F (31°C).

What is the hottest month in Abu Dhabi?

Weather in Abu Dhabi

Located in the Arabian Desert, Abu Dhabi has a subtropical desert climate classified as BWh according to the Köppen climate classification. This means:

  • Dry climate: low annual rainfall, averaging just 4 inches (100 mm) per year
  • Desert climate: low relative humidity, very hot summers, warm winters
  • Hot steppe climate: average annual temperature above 64.4°F (18°C)

The lack of rain and clouds leads to extreme shifts between day and night temperatures. However, humidity typically ranges 40–60% throughout the year.

Summer (June to September)

Summers are unrelentingly hot, sunny, and dry, with temperatures easily exceeding 100°F (38°C) most days.

The hottest month is August, with averages highs of 108°F (42°C) and lows of 88°F (31°C). However, temperatures frequently soar to as high as 113–122°F (45–50°C).

Cooling sea breezes provide some relief, especially in coastal areas. However, the Arabian Gulf waters remain quite warm during summer, reaching 90–95°F (32–35°C).

Winter (December to March)

Winters are warm and sunny, with average highs of 75–77°F (24–25°C) and average lows around 60°F (15°C). However, the desert cools off rapidly after sunset, with temperatures sometimes dropping as low as 41°F (5°C).

Occasional windstorms and rain showers happen during the winter months. However, total rainfall is only about 1 inch (25 mm) during the 3-month season.

Spring and Fall

During spring (March to May) and fall (October to November), temperatures are hot but more moderate than peak summer. Average highs range 85–100°F (29–38°C) while average lows range 65–75°F (18–24°C).

These shoulder seasons experience the most pleasant weather. Increased winds and blowing dust storms can happen but skies generally remain clear.

What Makes August the Hottest Month?

A few key factors contribute to make August the hottest month of the year in Abu Dhabi:

  • Peak sunlight intensity as the sun is directly overhead
  • Long duration of daylight hours
  • Warm Arabian Gulf waters heating surrounding land areas
  • Lack of cloud cover or rainfall
  • High humidity adding to heat index
  • Stifling overnight low temperatures providing little relief

By August, the sun has shifted to its most direct position for Abu Dhabi, which lies at 24°N latitude. With 12 hours per day of intense sunshine beating down, heat rapidly accumulates across the land.

The high humidity levels add to the oppressive heat. Furthermore, Arabian Gulf waters now reach their peak temperatures over 90°F (32°C), helping raise temperatures along the coastal regions of Abu Dhabi.

With largely clear skies throughout summer, sunlight and heat amass unobstructed day after day. The dry air and ground retain heat even overnight, leading to sweltering mornings. Thus, temperatures remain extremely hot around the clock in August.

So when combining ample sunshine, long days, high humidity, and consistently hot overnight lows, August takes the top spot for the hottest month in Abu Dhabi.

Coping with the Heat

Coping with the intense Abu Dhabi heat during August and summer takes some special measures:

Stay Hydrated

Drinking sufficient water and hydrating fluids is essential. Carry water wherever you go and sip regularly even when not thirsty. Avoid excess caffeine and alcohol which can dehydrate.

Dress Appropriately

Lightweight, light-colored clothing reflects heat better. Natural fabrics like cotton allow airflow to the skin. Sun protection like hats, glasses, and sunscreen lessen exposure.

Seek Shade

Resting in shaded or indoor areas provides relief, especially during peak daylight hours. Many public spaces have water misters.

Time Outdoor Activities Carefully

If exercising outside, do so in early morning or late evening once the sun has set. Pace activities slowly with frequent breaks.

Take Advantage of Air Conditioning

Virtually every indoor space has air conditioning. Malls, museums, restaurants, transport, and homes stay well air-conditioned.

Check on Vulnerable People

Elderly, very young children, outdoor workers, and people with health conditions need extra precautions like monitoring for signs of heat exhaustion.

So while the sweltering August heat can be difficult, taking proper preventative measures helps residents and visitors of Abu Dhabi stay cooler and safer.
