Delhi Weather Update: Fog and Poor AQI Mark Friday Morning, IMD Issues Rain Alert
Delhi residents began their Friday, January 30, 2026, under a blanket of fog and with air quality categorized as "poor". The India Meteorological Department (IMD) has issued warnings about an impending fresh western disturbance set to impact northwest India starting February 2. This weather system is influenced by the presence of a subtropical westerly Jet Stream over northeast India, which is driving these atmospheric changes.
Current Weather Conditions and Forecast
According to the latest IMD bulletin, Delhi is experiencing a generally cloudy sky with shallow to moderate fog expected at many places, and isolated areas seeing moderate fog during the morning hours. The temperature ranges are projected as follows:
- Maximum Temperature: 18°C to 20°C
- Minimum Temperature: 09°C to 11°C
Notably, the minimum temperatures are above normal by 1.6°C to 3.0°C, while maximum temperatures are appreciably below normal, ranging from -3.1°C to -5.0°C. Data from monitoring stations across the capital confirms this trend, with Palam recording the highest temperature departure. At Safdarjung, Delhi's primary weather station, the minimum temperature was 11 degrees Celsius, and the maximum reached 18.4 degrees Celsius.
Temperature Fluctuations and Rain Predictions
The IMD forecasts a drop in minimum temperatures by 3 to 4 degrees Celsius today and tomorrow, followed by a significant rise of 5 to 7 degrees Celsius thereafter. More critically, the weather agency has issued a yellow alert for heavy rains on January 31 and February 1, indicating potential disruptions and advising residents to stay prepared.
Air Quality and Visibility Report
Despite the foggy conditions, there is a silver lining in terms of air quality. The average Air Quality Index (AQI) showed marked improvement on January 30, largely due to recent rainfall. At 6:00 AM, the AQI stood at 231, which falls into the 'poor' category, as reported by the Central Pollution Control Board (CPCB). This represents a decrease from previous levels, highlighting the positive impact of precipitation on pollution.
In terms of visibility, Delhi's Indira Gandhi International (IGI) Airport reported 800 meters at 6:00 AM. Due to the fog, the airport implemented Low Visibility Procedures, but all flights continued to operate normally, according to a passenger advisory issued by Delhi Airport.
Looking Ahead: Western Disturbance Impact
The IMD's warning about the fresh western disturbance underscores the dynamic nature of Delhi's winter weather. Residents should anticipate:
- Continued foggy mornings in the short term.
- Heavy rainfall on January 31 and February 1, as per the yellow alert.
- Temperature swings, with an initial cooling followed by a warming trend.
This combination of factors—fog, fluctuating temperatures, and impending rain—calls for heightened awareness and precautionary measures, especially for travel and outdoor activities. Stay tuned to official updates from IMD for the latest weather developments.
