A Familiar Seasonal Pattern
Heavy humidity blanketed parts of the UAE on Tuesday morning. This sticky weather fits a very familiar and predictable seasonal pattern. Temperatures begin to fall overnight, but moisture remains abundant in the local air. This brings uncomfortable conditions and a heavily increased chance of morning fog. Moisture carried inland from the Arabian Gulf creates the conditions for high humidity. Clear skies, light winds, and falling overnight temperatures compound the sticky problem. The National Centre of Meteorology tracks these shifting weather systems closely. As the air near the ground cools, it moves closer to absolute saturation.
Transitioning Between Seasons
This specific pattern occurs during the transition from summer into autumn. The NCM expects humidity to remain elevated throughout the entire month of October. Cooler weather will not bring an immediate end to damp, sticky mornings. North-westerly winds carry moisture from the Gulf towards coastal and inland areas. When those winds weaken, moist air remains trapped close to the surface. Clear skies allow the ground to lose heat rapidly overnight. As the temperature falls towards the dew point, relative humidity rises sharply. Relative humidity measures how close the air is to saturation at its current temperature.
The Science Of Radiation Fog
A cooler morning can register a higher humidity reading than a hotter afternoon. When saturation occurs, water vapour condenses into tiny droplets, forming thick fog. High humidity makes warm weather feel more oppressive because sweat evaporates less readily. This severely reduces the human body’s natural ability to cool itself down. High pressure in the upper atmosphere limits rising air and traps moisture. This arrangement produces radiation fog, one of the most common types in the UAE. The NCM lists the month’s average maximum relative humidity at about 78 percent. Relief from the sticky conditions depends largely on falling winter temperatures.
