UAE temperatures to hit 50°C Wednesday as rain forecast for eastern regions
The National Centre of Meteorology predicts scorching heat reaching 50°C in internal areas, with afternoon convective clouds bringing rainfall to eastern and southern parts of the country amid gusty winds and blowing dust.
UAE temperatures to hit 50°C Wednesday as rain forecast for eastern regions
Temperatures in parts of the UAE are expected to reach 50°C on Wednesday, as the National Centre of Meteorology forecasts continued summer rainfall over eastern and southern regions following showers that swept the country a day earlier.
The federal meteorological agency, established in 2007 to provide weather forecasting and atmospheric research across the UAE, predicted fair to partly cloudy conditions nationwide. Convective clouds, locally known as Al Rawaih, are expected to develop during afternoon hours in eastern and southern areas, bringing a chance of rainfall accompanied by strong downdrafts and temporary temperature drops.
The forecast comes as the UAE experiences peak summer heat, with internal areas recording the highest temperatures between 45°C and 50°C. Coastal and island regions will see slightly cooler conditions at 39°C to 45°C, while mountainous areas are expected to range from 33°C to 39°C. While approaching the country's all-time record of 52°C set at Al Yasat Island in 2010, Wednesday's temperatures remain within typical ranges for this time of year.
Meteorological conditions driving weather patterns
The development of convective clouds results from the northward advance of the Intertropical Convergence Zone, a low-pressure belt near the equator where northeast and southeast trade winds converge. This phenomenon, combined with moisture drawn from the Sea of Oman and the influence of the Indian Summer Monsoon on regional atmospheric circulation, creates conditions favorable for afternoon cloud formation over eastern mountainous terrain.
High temperatures actually contribute to convective cloud development by enhancing surface heating, though additional atmospheric conditions including moisture, upper-air troughs, and favorable wind patterns are required for rainfall to occur. The NCM has conducted over 110 cloud seeding missions since the start of 2026 to enhance precipitation from suitable clouds and strengthen the country's water reserves.
Wind and humidity conditions
Winds are expected to remain light to moderate but may freshen at times, stirring up dust across the country. Wind speeds could reach 40 km/h over internal and mountainous areas and 35 km/h along coastal regions. Humidity will increase overnight and into Thursday morning over some coastal areas, raising the possibility of mist formation.
Sea conditions will remain slight in both the Arabian Gulf and the Oman Sea on Wednesday.
Extended forecast
Thursday will bring a decrease in temperatures, though winds reaching 40 km/h could cause blowing dust in western areas. The Arabian Gulf may become rough at times in western waters. The chance of afternoon convective clouds developing in eastern regions will continue on Friday and Saturday, with winds potentially reaching 35 km/h. Conditions are expected to remain fair to partly cloudy on Sunday.
The current weather pattern occurs just days before the traditional rising of the Suhail star on August 24, which marks the beginning of a gradual decline in temperatures and the end of peak summer in the UAE.
