What happened?
The UAE recorded its highest temperature of 2026 at 51.2°C in Budu Dafs, Al Dhafra, on August 5, according to the National Center of Meteorology (NCM).
Who is affected?
Residents across the UAE, particularly those working outdoors, travellers, motorists and businesses operating in extreme heat.
Why does it matter?
The record temperature highlights the peak of the UAE’s summer season while reminding residents to stay prepared for both extreme heat and sudden thunderstorms.
The UAE has recorded its hottest temperature of the year after the mercury climbed to 51.2°C in Budu Dafs, Al Dhafra, on August 5, according to the National Center of Meteorology (NCM). The record was registered at 12:45pm, making it the highest temperature recorded across the country in 2026 so far. The milestone comes as the UAE experiences the final days of its annual peak summer period, while weather authorities continue to forecast convective clouds and rainfall in several parts of the country despite the extreme heat.
Where was the UAE’s highest temperature recorded?
According to the NCM, the highest temperature was recorded in Budu Dafs in the Al Dhafra region of Abu Dhabi at 51.2°C.
The new reading surpasses the 50°C recorded in Al Shawamekh, Abu Dhabi, on August 1 and marks the hottest day the UAE has experienced this year.
Although temperatures above 50°C are uncommon, they are not unprecedented during the country’s peak summer months. Inland desert regions such as Al Dhafra regularly experience significantly higher daytime temperatures than coastal cities because of lower humidity and intense solar heating.
The NCM also released a temperature map showing the highest readings across different parts of the UAE on August 5.
Why is the UAE experiencing such extreme heat?
The record temperature coincides with Jamrat Al Qayth, traditionally recognised as the hottest period of the UAE’s summer.
This seasonal phase usually lasts until August 10 and represents the final stretch of intense summer heat before temperatures gradually begin to ease later in the month.
Astronomers also note the appearance of Al Mirzam (Sirius) in the early morning sky during this period. In Emirati tradition, the star’s rise signals the beginning of the last phase of extreme summer weather before seasonal conditions slowly transition towards autumn.
While daytime temperatures remain exceptionally high, humidity levels often increase along coastal areas, making conditions feel even hotter.
Why is it raining despite temperatures above 50°C?
The combination of extreme heat and rainfall may seem unusual, but meteorologists say the two weather events can occur together.
According to the NCM, heat alone does not produce rain. Rainfall develops when several weather conditions align, including:
- High atmospheric moisture
- Humid air masses
- Atmospheric instability
- Upper-air troughs
- Favourable wind patterns
When these conditions combine, intense surface heating encourages the formation of convective clouds, which can quickly develop into thunderstorms and heavy showers.
This explains why parts of Fujairah experienced heavy rainfall and flowing wadis on the same day temperatures elsewhere exceeded 51°C.
The NCM also confirmed that cloud-seeding flights were carried out whenever suitable cloud formations were available during the recent rainy spell.
What does this mean for UAE residents and businesses?
Extreme temperatures affect almost every aspect of daily life across the UAE.
Outdoor workers, construction companies, delivery services and logistics operators continue to adapt their operations during the hottest weeks of summer. The country’s Midday Break regulations remain an important measure to protect outdoor workers from heat stress during peak afternoon hours.
Motorists are also encouraged to check tyre pressure, coolant levels and vehicle batteries, as prolonged exposure to extreme heat increases the risk of breakdowns.
Residents spending time outdoors are advised to:
- Stay hydrated throughout the day.
- Avoid prolonged exposure to direct sunlight.
- Wear lightweight clothing.
- Follow official weather alerts issued by the NCM.
- Exercise caution near valleys and low-lying areas during rainfall, where flash flooding can occur.
Meanwhile, airlines, tourism operators and event organisers continue monitoring weather conditions to ensure visitor safety during the busy summer travel season.
What weather can the UAE expect next?
The NCM expects unstable weather conditions to continue until August 7, with convective cloud formation likely over eastern and southern parts of the country.
Some areas could experience rainfall, lightning, gusty winds and reduced visibility during thunderstorms.
Although the most intense phase of summer is expected to end around August 10, residents should still expect very hot daytime temperatures throughout August before seasonal cooling gradually begins later in the year.
The NCM continues to issue regular forecasts and weather alerts, encouraging residents to stay updated through its official channels.
Why It Matters
The UAE’s record temperature serves as a reminder that summer conditions remain severe, even as the country approaches the end of its hottest seasonal period.
For residents, it means taking extra precautions when travelling or spending time outdoors. Businesses with outdoor operations must continue following workplace safety measures, while motorists should prepare for the impact of prolonged heat on vehicles.
At the same time, the recent rainfall highlights how rapidly weather conditions can change during summer, making official weather updates more important than ever.
FAQs
What is the highest temperature recorded in the UAE in 2026?
The highest temperature recorded so far in 2026 is 51.2°C, measured in Budu Dafs, Al Dhafra, on August 5.
Why is the UAE experiencing rain during extreme heat?
Rain develops when moisture, atmospheric instability and favourable weather conditions combine with intense surface heating to form convective clouds.
What is Jamrat Al Qayth?
Jamrat Al Qayth is the UAE’s traditional hottest period of summer, lasting until around August 10 each year.
Will temperatures start to cool after August?
Temperatures generally begin to ease gradually after the peak summer period, although hot weather continues through much of August.
Where can residents check official weather updates?
Residents should follow forecasts and alerts issued by the National Center of Meteorology (NCM).
The UAE’s highest temperature of the year reflects the country’s annual peak summer season, but it also demonstrates how rapidly weather conditions can change, with thunderstorms and rainfall occurring alongside extreme heat. As temperatures remain high over the coming days, residents are encouraged to stay informed through official weather updates and take the necessary precautions.
