The UAE has entered its summer transition in unmistakable fashion, with temperatures surpassing 40°C across multiple regions and forecasters warning that the heat is set to intensify further in the weeks ahead. Residents and outdoor workers are being urged to take precautions as the country moves from a mild spring into what could be one of its more demanding summers on record.
The Numbers: How Hot Has It Got?
The mercury could reach up to 41°C in inland areas, with humidity rising to as high as 70 per cent. Coastal cities, including Abu Dhabi and Dubai, are also likely to see temperatures exceeding 40°C this week.
The highest temperature on Saturday was 43.3°C in Al Quaa in Al Ain, and the National Centre of Meteorology issued a 12-hour yellow alert warning of strong north-westerly winds reaching up to 40 km/h, along with rough sea conditions in the Arabian Gulf with waves up to 1.8 metres.
For Monday, April 27, temperatures are set to increase further, with mercury across the country reaching up to 42°C. Dubai is forecast to see highs of up to 37°C, while Abu Dhabi will see highs of up to 38°C. Gusts are expected to freshen at times, causing blowing dust northward and eastward.
Why April Feels Like Summer Already
On Monday, temperatures in parts of the country touched 40°C, a notable spike for April and several degrees above the typical range for this time of year. Average highs usually hover between 32°C and 34°C along coastal areas and 34°C to 36°C inland, making this early surge an exception rather than the rule.
The latest rise is part of a broader transition period where alternating wind directions are causing noticeable swings in temperatures across coastal and inland areas.
The country is still within what is locally known as the Sarrayat season, a transitional spring period typically running from mid-March to early May, marked by sudden and short-lived weather fluctuations. Originating between northern India, Pakistan and Iran, this system draws in hot and humid air masses, gradually pushing temperatures higher across the Gulf.
This year’s pattern has been particularly erratic. Some coastal cities saw temperatures stay below 30°C, while certain inland areas recorded lows dropping below 15°C and even below 10°C in locations such as Raknah, well below the seasonal average, before the sharp reversal into intense heat took hold within days.
What the Rest of the Season Looks Like
By this point, expect temperatures to consistently exceed 40°C across most of the country. Southern and deep-inland areas, particularly the Al Dhafra region and the desert stretches near Al Ain and Sweihan, could see peak readings approaching 50°C during the height of summer. In 2024, the National Centre of Meteorology confirmed that parts of the UAE surpassed 50°C at peak.
The hottest temperature ever officially recorded in the UAE was 52.1°C, recorded in the shade by specialist calibrated equipment in July 2002.
The astronomical calendar marks the official start of summer on June 21, 2026, the summer solstice, when the UAE experiences its longest day of approximately 13 hours and 43 minutes of daylight. By June, afternoon temperatures across Dubai, Abu Dhabi, and Sharjah are typically already hovering between 41°C and 43°C, with nights offering only partial respite in the 26°C to 29°C range.
El Nino conditions typically amplify existing temperature trends across the Gulf, bringing warmer-than-average sea surface temperatures and more intense heat. If the forecast materialises, summer 2026 could be among the more intense on record for the UAE, raising the stakes for heat safety, energy demand, and outdoor work regulations.
Worker Protection: The UAE’s Midday Ban
As temperatures climb, the UAE’s long-standing outdoor work protections become increasingly relevant. The midday break ban runs annually from June 15 to September 15, prohibiting all outdoor work between 12:30 PM and 3:00 PM, under the rules of the Ministry of Human Resources and Emiratisation. The regulation applies to all work conducted directly under the sun, particularly in construction and infrastructure sectors.
Compliance remains among the highest globally, improving from 99 per cent in 2022 to 99.9 per cent in 2023, supported by close cooperation between private companies and regulators. Employers are required not only to suspend outdoor work during the restricted hours but also to provide shaded rest areas, drinking water and other preventive measures.
The financial consequences for non-compliance are significant. Firms caught violating the outdoor work ban face a penalty of AED 5,000 per employee, up to a maximum of AED 50,000 in cases of repeated violation.
Heat Safety Essentials for Residents
With the summer intensifying, authorities and health professionals consistently advise the following:
- Drink water regularly throughout the day, even when not feeling thirsty
- Avoid outdoor physical activity between noon and 3:00 PM
- Wear light, loose, and breathable clothing when outdoors
- Keep vehicles well-ventilated before entering after they have been parked in the sun
- Watch for signs of heat exhaustion, including dizziness, nausea, and excessive sweating
- Never leave children or pets unattended in parked vehicles
What Happens Next
The National Centre of Meteorology confirmed that temperatures will tend to increase on Monday and again on Wednesday, as the country continues its transition towards summer.
With summer 2026 potentially shaping up to be an intense one, energy consumption, cooling infrastructure, and outdoor worker safety will all be under the spotlight. The UAE’s proactive regulatory framework, combined with its climate-resilient urban planning, positions the country well to manage the season. However, the next several weeks will test that readiness as the heat continues its steady advance across every emirate.
FAQs
How hot is the UAE right now in April 2026?
Temperatures have already crossed 40°C in several inland and coastal areas, with the highest recorded reading of 43.3°C in Al Quaa, Al Ain. Forecasters expect temperatures to rise further through late April and into May.
Is this level of heat normal for April in the UAE?
No. Average April highs typically range between 32°C and 34°C along the coast and up to 36°C inland. Readings above 40°C in April represent a notable early surge and are above the seasonal norm.
When does the UAE outdoor work ban come into effect?
The mandatory midday outdoor work ban runs from June 15 to September 15 each year, prohibiting all outdoor work under direct sunlight between 12:30 PM and 3:00 PM. Violations carry fines of up to AED 5,000 per worker.
How hot can the UAE get during peak summer?
Deep inland areas such as Al Dhafra, Sweihan, and stretches near Al Ain can approach or exceed 50°C at peak summer. The UAE’s all-time official record stands at 52.1°C, recorded in July 2002.
When does summer officially begin in the UAE in 2026?
Astronomically, summer begins on June 21, 2026, the summer solstice. However, in practical terms, intense summer-like heat typically arrives well before that date, as conditions in April and May already demonstrate.
