Dense fog spread across parts of the UAE, prompting authorities to issue a red alert as visibility dropped sharply, with motorists urged to exercise caution and follow official safety advisories.
UAE weather: Dense fog covers areas nationwide; authorities issue red alert
UAE residents can expect clear to partly cloudy conditions on Saturday, January 3, 2026.
The National Centre of Meteorology has issued yellow and red fog warnings from midnight until 10am today. The NCM cautioned that humidity levels will rise by Saturday night and Sunday morning in some inland areas, increasing the likelihood of fog or mist forming. Winds will be light to moderate, occasionally strengthening over the sea and causing dust. Northwesterly to southwesterly winds are forecast at speeds of 10 to 20kmph, with gusts reaching 30kmph.
In Abu Dhabi, temperatures are expected to drop to 15°C and rise to a high of 24°C. Dubai will see temperatures ranging from 13°C to 24°C on Saturday, according to the NCM’s latest update. The lowest temperature across the country on Friday morning was recorded at 3.7°C in Raknah, Al Ain, at 5.45am, while the highest reached 26.5°C in Kalba, Sharjah, at 1.15pm, the NCM reported.
Meanwhile, Yousef Al Qasimi, a member of the Emirates Astronomical Society, said light frost was observed early Friday morning in Raknah. Although official weather stations registered temperatures near 4°C, on-site measurements indicated readings close to one degree above zero.
Weather experts note that winter conditions in the UAE often bring cooler nights and early morning fog, especially in inland and desert regions. As temperatures drop after sunset, moisture in the air condenses near the ground, creating misty conditions by dawn. These patterns are common during this time of year and may continue intermittently through January. Residents are advised to remain cautious during early morning travel, particularly on highways and open roads, where sudden fog patches can significantly reduce visibility and increase the risk of accidents if drivers are unprepared.
Marine conditions are also being closely monitored as winds strengthen over coastal waters. Fishermen and small boat operators are advised to check sea condition updates before heading out, as stronger winds can create rougher waves and reduced visibility. Authorities often issue marine advisories during such periods to ensure safety. Recreational beachgoers are encouraged to follow instructions from lifeguards and avoid venturing into the sea when conditions are unfavourable. Monitoring official bulletins can help residents plan outdoor and marine activities safely.
Health specialists recommend dressing in layers during cooler mornings and evenings, as temperatures can vary significantly throughout the day. Sudden exposure to cold air, combined with humidity, may cause discomfort for individuals sensitive to temperature changes. Elderly residents and children are advised to take extra precautions during early morning hours. Staying hydrated and maintaining a balanced routine can help the body adjust to fluctuating weather. Light physical activity indoors during foggy periods may also help maintain overall wellbeing.
Agricultural experts say cooler temperatures and increased humidity can benefit certain crops, particularly vegetables grown in inland farms. However, frost conditions, even when light, may pose risks to sensitive plants. Farmers are advised to monitor temperature forecasts closely and take protective measures when necessary. Covering crops and adjusting irrigation schedules can help minimise damage. Seasonal weather variations play a significant role in agricultural planning, making accurate forecasts essential for farmers across different regions of the UAE.
The NCM has reiterated that residents should rely on official channels for weather updates and alerts, as conditions can change rapidly. Fog and humidity levels may vary from one area to another within short distances. Authorities encourage the public to remain informed and prepared, particularly during early morning hours. By following safety guidelines and staying updated, residents can reduce weather-related risks and continue daily activities with greater confidence during the winter season.
