Dense morning fog is rolling across the United Arab Emirates today, with visibility expected to plummet overnight and into early morning in Dubai, Abu Dhabi, and Sharjah. Combined with temperatures reaching 45-49°C across the emirates and humidity peaking at 70-90% in coastal areas, the National Centre of Meteorology has warned residents to take precautions during tomorrow's morning commute.
What to Expect Today and Tomorrow Morning
The National Centre of Meteorology forecasts temperatures rising to 49°C in Liwa, 47°C in Al Ain, 46°C in Abu Dhabi, 45°C in Dubai and Sharjah, and 44°C in Ajman and Ras Al Khaimah. Fujairah will see slightly cooler conditions at 36°C. Overnight lows will range from 29-34°C depending on location.
Dense fog is expected to form overnight through early morning, reducing visibility to less than 1,000 meters in affected areas. This combination of fog and high humidity creates hazardous driving conditions for tomorrow's commute.
Fog Safety: What Drivers Need to Know
Abu Dhabi Police will enforce speed restrictions of 80 km/h on affected roads during fog periods. Dubai Police will issue real-time alerts through social media and smartphone warning systems when visibility drops below 100 meters.
Drivers should follow these essential precautions:
• Activate low-beam headlights only (high beams reflect off fog and reduce visibility)
• Maintain an extended following distance of at least 150 meters
• Avoid sudden lane changes and overtaking
• Depart earlier than usual to allow extra time for cautious driving
• If visibility becomes too poor, pull into a petrol station or service road
Heavy vehicles exceeding 2.5 tons—including delivery trucks, cement mixers, and construction equipment—face restrictions or bans during foggy periods and peak traffic windows. Violations result in fines and traffic black points.
Heat and Humidity Combined
With humidity reaching 70-90% in coastal areas, residents will experience a "feels like" temperature significantly higher than recorded readings. High humidity prevents sweat from evaporating efficiently, the body's primary cooling mechanism. This can accelerate dehydration and heat-related illness, particularly for outdoor workers, elderly residents, and those with chronic conditions.
Practical Safety Reminders
For commuters: Monitor weather forecasts hourly, as fog density changes rapidly. Assume fog exists during early morning hours until confirmed otherwise by authorities.
For all residents: Stay hydrated throughout the day. Thirst lags behind actual dehydration by 15-20 minutes, so drink water regularly even if you don't feel thirsty. Those with asthma, heart conditions, or kidney disease should consult their physicians about activity adjustments during heat spikes.
For employers: Enforce indoor breaks for outdoor workers, provide electrolyte beverages in addition to water, and watch for signs of heat stress including confusion, excessive fatigue, or disorientation.
This combination of fog and heat is typical for August in the UAE. With proper precautions and awareness, residents can navigate these conditions safely.
