Delhi Braces for 6°C Chill: IMD Forecasts Dense Fog and Worsening AQI
Delhi temperature to drop to 6°C, dense fog forecast

The national capital is preparing for a severe cold spell as the India Meteorological Department (IMD) predicts a significant dip in mercury levels over the coming days. Residents of Delhi and several northern states are likely to experience intense cold wave conditions, dense fog, and deteriorating air quality.

Sharp Temperature Drop and Chilling Forecast

The IMD has forecast a fall in temperature by 2-3 degrees Celsius across Delhi and the National Capital Region within the next three days. This chilling prediction follows a cold Friday morning where Delhiites woke up to a minimum temperature of 11.2 degrees Celsius recorded at 5:30 AM. The weather office has indicated that by December 4, the minimum temperature could plunge to a bone-chilling 6 degrees Celsius in Delhi and its adjoining areas.

This forecast marks a continuation of the cold trend. On Wednesday, January 1, 2026, Delhi had already recorded its lowest daytime temperature for New Year's Day since 2019, settling at 14.2 degrees Celsius.

Widespread Fog and Prolonged Cold Wave

The IMD's weather alert extends beyond just low temperatures. The department has warned that dense to very dense fog conditions are very likely to persist during night and morning hours for the next 5-7 days. This fog blanket is expected to cover many places across a vast swathe of North and East India, including:

  • Punjab
  • Haryana & Chandigarh
  • Delhi
  • Uttar Pradesh
  • Bihar
  • Odisha

Furthermore, the IMD has issued a cold wave warning for specific regions and dates:

  • Isolated pockets of Himachal Pradesh till December 4.
  • Punjab, Haryana, Chandigarh, and Delhi during December 2-5.
  • Rajasthan during January 4-7, 2026.

The weather forecast from the IMD is valid until December 8.

Air Quality Worsens Amidst Cold Conditions

Compounding the discomfort from the cold, the air quality in Delhi has also taken a hit. On Friday morning, the Air Quality Index (AQI) was recorded at 321, which falls into the 'Very Poor' category. The combination of low temperatures, fog, and stagnant winds is trapping pollutants close to the ground, leading to this deterioration in air quality. Residents are facing a dual challenge of braving the cold while also dealing with unhealthy air.

As the city gears up for this harsh weather, people have already begun seeking warmth around bonfires, a common sight during Delhi's winters. Authorities are advising citizens, especially the vulnerable populations, to take necessary precautions against the cold and to limit outdoor activities during early morning and late evening hours when fog and cold are at their peak.
