Cold wave in Delhi: Dense fog disrupts traffic movement, IMD predicts some respite soon

Delhi's minimum temperature rose slightly to 3.8 degrees Celsius on Wednesday morning, compared to 3 degrees Celsius on Tuesday. Dense fog conditions accompanied the cold, particularly during early mornings in the national capital, reducing visibility and affecting transport in and around the capital.

The dense fog, however, has now begun to clear out. Visuals showed thick fog blankets in several neighbourhoods, with commuters reporting disrupted schedules and slower traffic.

Minimum temperatures recorded across Delhi as of 08:30 am on Wednesday

• Safdarjung 3.8 degree Celsius
• Ridge 4.6 degree Celsius
• Palam 4.4 degree Celsius
• Ayanagar 4.0 degree Celsius
• Lodi Road 3.6 degree Celsius

On Wednesday, the India Meteorological Department (IMD) reported a slight increase in the minimum temperature compared to the previous day, although the chill remained evident. The IMD, however, has signalled a shift, projecting a gradual rise in the city's minimum temperature in the coming days, offering possible relief to those affected.

The IMD stated that the minimum temperature is likely to increase by 3 to 5 degrees Celsius over the next five days. The national capital experienced a sharp drop in temperature on Tuesday, with the minimum plunging to 3 degrees Celsius, marking the coldest morning of the season so far. For several days, Delhi has faced a persistent cold spell, impacting daily routines and outdoor activities. 

Tuesday’s 3 degrees Celsius minimum cemented the day as the coldest morning in the current season. Such temperatures are well below the January average for Delhi, underscoring the intensity of the ongoing cold wave. The IMD’s forecast, if realised, would bring the minimum temperature back in line with seasonal norms, alleviating the discomfort caused by the recent plunge.

The air quality index (AQI) has also remained a concern, with recent readings placing Delhi’s air in the 'very poor' category with AQI at 360. According to the AQI classification, readings between 301 and 400 are considered 'very poor', while values above 400 are termed 'severe'. Some monitoring stations have even recorded values approaching the 'severe' threshold, prompting health advisories.

AQI categories, as defined by local authorities, are: 'good' (0–50), 'satisfactory' (51–100), 'moderate' (101–200), 'poor' (201–300), 'very poor' (301–400), and 'severe' (401–500). These classifications help residents understand daily health risks and take necessary precautions.
