Has winter ended in Delhi? Rising temperatures raise questions, IMD responds

Delhi recorded its warmest January day since 2019 on January 19, with a maximum temperature reaching 26.1°C. This year’s peak winter season, generally spanning from December 27 to January 20, experienced fewer cold days and nights.
The national capital is facing unusual weather patterns, with warm daytime temperatures and cooler nights. Since Sunday, Delhi has recorded maximum temperatures significantly higher than the seasonal average. The India Meteorological Department (IMD) has indicated that the city is expected to experience smog or shallow to moderate fog in most areas on Friday morning. While the day is predicted to have a mostly clear sky, smog or shallow fog is anticipated to return in the evening and night.
Additionally, several flights at Indira Gandhi International (IGI) airport experienced delays on Friday due to the foggy conditions.
Why is Delhi warm suddenly?
The India Meteorological Department (IMD) has said that a strong western disturbance is causing the warmer weather in the region. This winter, Delhi has experienced its mildest peak in nine years, with no instances of ‘cold day’ or ‘cold wave’ conditions for the first time since the winter season of 2017-18.
Furthermore, the IMD has forecasted a decrease in both maximum and minimum temperatures in the upcoming days. A new western disturbance has led to snowfall in the mountains, resulting in a shift of winds to a north-westerly direction. Consequently, temperatures are expected to drop by 3 to 4 degrees Celsius by the weekend.
Meanwhile, Delhi recorded its warmest January day since 2019 on January 19, with a maximum temperature reaching 26.1°C. This year’s peak winter season, generally spanning from December 27 to January 20, experienced fewer cold days and nights. According to IMD data, it is the mildest winter since the 2015-16 season, with an average low temperature of 9°C, which is two degrees above the average.
