UAE heatwave ~~persists with rain, dust and cloud‑seeding~~ transitions to cooler, humid autumn weather

The extreme summer pattern that began in late June 2025 ~~has~~ continued into the summer of 2026. ~~On 27 July,~~ Throughout July and August, the UAE experienced intense heat with temperatures reaching 50.4 °C, alongside cloud-seeding missions, thunderstorms, and hail. By late August, a seasonal transition began, and by early September, the National Centre of Meteorology (NCM) ~~forecast interior~~ noted a shift toward autumn with daytime highs expected below 39 °C. By early October, temperatures up continued to ~~48 °C, coastal~~ decrease as summer conditions receded. Daytime highs ~~between 42~~ dropped below 40 °C ~~and 37 °C,~~ in most emirates, with Fujairah seeing cooler temperatures around 35 °C and ~~overnight humidity near 90%. By 31 July, cloud-seeding missions were launched to combat intermittent peaks of 50 °C. In early August,~~ Abu Dhabi reaching the ~~NCM warned of a multi-day period of showers affecting eastern, southern, and inland areas. During this time, interior temperatures reached~~ 40 °C threshold. High humidity, reaching up to ~~50 °C, while~~ 90% in several major cities ~~like Dubai and~~ including Abu ~~Dhabi peaked around 46 °C. By 9 August, heavy thunderstorms, rainfall, and hail were reported, particularly in eastern~~ Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain, and ~~southern regions including~~ Ras Al ~~Ain. By 14 August, extreme heat persisted, with Bada Dafas in~~ Khaimah, has led to the ~~Al Dhafra region recording 50.4 °C. By mid-August, weather patterns began a complex transition. While temperatures remained high, near 50 °C, rainfall~~ formation of mist or fog in ~~areas like the Margham oil~~ coastal and ~~gas field provided some relief.~~ inland regions. The ~~approach of the Suhail star around 24 August traditionally signals the end of peak summer heat, though the~~ NCM noted that cooling is actually driven by decreasing solar radiation. Despite this seasonal shift, unsettled weather persisted through late August. An extension of a surface low-pressure system caused temperatures in inland regions has advised drivers to ~~reach between 45 °C and 49 °C, accompanied by strong wind gusts of up~~ exercise caution due to ~~45 km/h that could stir up dust and sand. By 31 August, the country began entering a cooling period; forecasts for September indicated~~ potential drops in visibility. While daytime ~~highs would likely stay below 39 °C as the transition to autumn commenced. In early September, the NCM issued warnings for high temperatures reaching up~~ conditions have remained generally fair to ~~46 °C~~ partly cloudy, convective clouds have been observed in ~~internal regions,~~ eastern areas, with ~~coastal highs between 37 °C and 42 °C.~~ an increased possibility of rainfall as weather conditions become more unsettled.
