Weather forecast: Is fog back in UAE? Why September humidity is triggering foggy mornings in Dubai, Abu Dhabi

## Fog Alerts Issued in UAE

The National Centre of Meteorology (NCM) has issued a fog alert for September 2, 2026, warning of reduced visibility from 1am to 8:30am in coastal and inland areas of the UAE. The increase in humidity, reaching around 90% overnight, is contributing to the formation of fog, particularly in Dubai and Abu Dhabi.

## Understanding Fog Formation

Fog in the UAE is primarily caused by radiation fog, which occurs when warm, moist air from the Arabian Gulf and Sea cools rapidly after sunset. This cooling leads to condensation of water vapor into tiny droplets near the ground. Light winds and dust particles in the air further aid in fog formation.

## Seasonal Patterns

The current foggy conditions align with the Suhail season, beginning on August 24, when humidity levels rise as summer heat starts to recede. This period is traditionally associated with increased fog and dew in the mornings.

## High-Risk Areas

Fog tends to form in specific regions, notably the Sweihan desert and areas southwest of Abu Dhabi. These locations cool quickly at night, making them prone to fog. Key roads such as those linking Abu Dhabi, Al Ain, and Dubai, as well as parts of Al Dhafra, are often affected.

## Safety Measures

Authorities have implemented a color-coded alert system to inform residents of fog conditions. Drivers are advised to exercise caution, maintain safe distances, and use headlights appropriately. The NCM emphasizes the importance of staying informed through official weather updates.

## Future Weather Expectations

As September progresses, temperatures are expected to gradually decrease, potentially increasing fog occurrences. Residents are encouraged to check forecasts before traveling, especially in the early morning hours, to avoid delays and ensure safety.
