Winter Returns To Delhi-NCR: Dense Fog, Temp Drops To 14°C; IMD Issues Green Alert, Check Rain Update

Residents of Delhi-NCR woke up to an unusual weather change on Saturday morning, as dense fog covered several parts of the region. The temperature dropped to around 14°C, bringing a surprising chill after days of intense heat.

The thick fog led to very low visibility, especially on roads and highways, making travel slower and slightly risky in some areas. Many people felt as if winter had briefly returned, offering relief from the recent heatwave.

Rainfall Triggers Foggy Conditions

The sudden change in weather comes after rainfall on Friday evening, which increased moisture in the air. This moisture, combined with cooler temperatures overnight, led to the formation of dense fog early in the morning.

Such weather patterns are not very common during this time of the year, making the situation even more noticeable for residents.

Temperature Forecast for the Day

According to weather reports, the temperature is expected to:

• Rise to around 25°C during the day
• Drop again to nearly 16°C by midnight

This means Delhi-NCR will experience a pleasant and cool day, a welcome break from the rising temperatures seen recently.

IMD Issues Green Alert for Saturday

The India Meteorological Department (IMD) has issued a green alert for Delhi on Saturday, March 21, indicating no major weather warnings for the city.

However, the IMD has predicted partly cloudy skies throughout the day. The maximum temperature is expected to range between 26-28°C, while the minimum temperature may stay between 13-15°C.

This forecast suggests stable weather conditions despite the presence of fog in the morning hours.

Sunday Weather Outlook

Looking ahead to Sunday, March 22, 2026, Delhi is expected to see a partly cloudy sky that may turn generally cloudy by evening.

• Day temperatures: Likely between 29-31°C
• Night temperatures: Expected around 15-17°C
• Wind conditions: Light winds from the north and northeast

The gradual rise in temperature indicates that the brief cool spell may start fading from Sunday onwards.

Role of Western Disturbances

Meteorologists say that this sudden cooling is mainly due to a western disturbance, a weather system that brings rain and snow to northern parts of India.

Heavy snowfall in higher altitude regions like Sonmarg and Himachal Pradesh has also contributed to the drop in temperature across the plains. The cold air from these regions moves downward, affecting cities like Delhi and nearby areas.

Impact on Daily Life and Travel

The dense fog has affected road visibility, especially during early morning hours. Drivers are advised to:

• Use fog lights while driving
• Maintain safe distance between vehicles
• Avoid high speeds

Air travel may also face delays due to changing weather conditions.

IndiGo Issues Travel Advisory

Amid changing weather conditions, IndiGo Airlines issued a travel advisory for passengers, especially those flying to and from Kolkata. The airline warned that thundershowers could affect flight schedules.

Passengers were advised to:

• Check their flight status before leaving for the airport
• Allow extra travel time due to possible traffic delays
• Stay updated through the airline's website or mobile app

The airline also assured that teams are working to manage operations smoothly despite weather challenges.

A Brief Relief from Heatwave

For many residents, this sudden dip in temperature feels like a short break from the harsh heatwave that had been affecting Delhi-NCR. While the cooler weather is temporary, it has brought much-needed comfort.

However, experts say that temperatures may rise again in the coming days once the effect of the western disturbance weakens.

The unexpected fog and cooler temperatures in Delhi-NCR highlight how quickly weather can change due to atmospheric conditions. While it has brought relief from the heat, it has also created challenges like low visibility and travel delays.
