As the new work and school week begins on Monday, September 21, 2026, the National Centre of Meteorology (NCM) has issued a red alert for dense fog across parts of the UAE. The warning remains in effect until 8:00 AM, advising residents to exercise caution during their morning commutes. While the day is expected to be generally fair to partly cloudy, residents should keep an eye on the skies in eastern regions, where clouds are likely to gather and potentially turn convective by the afternoon.

Those heading outdoors should prepare for sweltering conditions, with nationwide temperatures expected to peak at 45°C. Dubai will reach this high with a low of 31°C, while Abu Dhabi and Sharjah will see similar heat, hitting maximums of 44°C. Looking ahead to Monday night and Tuesday morning, the region will face increased humidity, which may lead to further instances of mist or fog in coastal and internal areas. Winds will remain light to moderate throughout the day, occasionally picking up speed to 35 km/hr, while sea conditions are forecast to stay relatively calm across both the Arabian Gulf and the Oman Sea.
