On Sunday, a video shared by the Storm Centre showed heavy rain falling in Masafi, Fujairah, a sudden drenching in a landscape more accustomed to dust. The day before, the mercury had touched 50°C in Al Shawamekh, Abu Dhabi, at 2.30pm. It was a stark prelude to a week in which the Gulf’s summer heat would repeatedly collide with unstable skies.

The UAE’s National Centre of Meteorology (NCM) expects the pattern to hold through August 6. Each afternoon, convective clouds are forecast to build over eastern and southern areas, sometimes spreading inland, bringing a chance of rain. The immediate cause, the NCM said, is an extension of a surface low-pressure system from the east, coupled with a weak upper-air low. Winds will be light to moderate, southeasterly to northeasterly, freshening at times to 40 km/h and raising dust. Meteorologist Ahmed Habib told Khaleej Times that the ongoing El Niño pattern could be contributing to the unusual summer rainfall. The NCM’s August climate report notes that the country is under the influence of the Indian seasonal low-pressure system and thermal lows from the southwest, which, combined with intense daytime heating and the eastern mountains, encourage the formation of convective clouds. During the first half of the month, the Intertropical Convergence Zone can also enhance rain-bearing clouds.

The instability stretches beyond the Emirates. Saudi Arabia’s National Center for Meteorology forecast thunderstorms across parts of Asir, Jazan, Al Baha, the Makkah highlands and Najran through the end of the week, urging residents to monitor its Anwaa app and social media channels. In Oman, heavy thunderstorms were expected to persist over the Hajar Mountains, with cumulonimbus clouds extending into the North Al Sharqiyah, South Al Sharqiyah and Al Dhahirah governorates, bringing scattered showers and strong winds.

For residents, the forecasts have become a daily ritual of checking apps and sharing videos of rain sweeping through wadis. The NCM’s August climate report notes that the month is typically one of intense heat and rising humidity, with average daytime highs between 40.9°C and 43.2°C and relative humidity reaching around 47 per cent in the second half. Yet the records also hold the memory of more dramatic events: the highest August rainfall ever recorded in the UAE was 100.4 mm at Hamim in 2013, and the strongest wind gust reached 127.8 km/h in Al Hayer in 2023.

By Monday afternoon, the clouds would build again over the eastern mountains, and the rain would return, a fleeting reprieve before the heat reasserted itself. The seas remained slight, but the winds carried the dust of the interior, and the cycle of sun and sudden shower continued, a reminder that even in the desert, the sky can surprise.
