Delhi Air Quality Plummets to Severe Levels, Stage 3 GRAP Restrictions Enforced
The air quality in Delhi has taken a sharp turn for the worse. Forecasts now predict a slide into the 'Severe' category. In response, authorities have acted swiftly.
The Commission for Air Quality Management (CAQM) for the National Capital Region and Adjoining Areas made a critical decision on Friday. They invoked anti-pollution measures under Stage III of the Graded Response Action Plan (GRAP). These curbs take effect immediately.
Current Air Quality and Weather Conditions
Delhi's Air Quality Index (AQI) was recorded at 354 on Friday. This marks a rise from Thursday's reading of 343. Both figures fall within the 'Very Poor' category, but the trend is alarming.
Weather experts warn of further deterioration. The India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology issued a joint forecast. They cite unfavourable weather conditions and low, variable wind speeds as key factors driving the pollution spike.
Meanwhile, temperatures in the capital remain chilly. The minimum temperature slightly increased to 4.3 degrees Celsius on Friday. However, this is still three degrees below the normal range for this time of year. Thursday was even colder, recording a night temperature of 2.9 degrees Celsius, making it the coldest day of the season so far. The maximum temperature on Friday reached 22.5 degrees Celsius.
GRAP Stage 3: What Restrictions Are Now in Place?
The activation of GRAP Stage 3 triggers several significant public health measures. These are designed to curb pollution sources and protect residents.
- Schools: All schools must switch to a hybrid mode of teaching. This means they must offer both online and offline classes to reduce student exposure.
- Private Vehicles: BS-III petrol and BS-III diesel private vehicles will face operational restrictions within the city.
- Commercial Vehicles: A strict ban is now in effect. BS-IV diesel-operated Light Commercial Vehicles (LCVs) registered outside Delhi cannot enter the capital. Exceptions are made only for vehicles carrying essential commodities or providing essential services.
- Older Commercial Vehicles: An even tighter restriction applies to BS-III and older diesel commercial vehicles registered outside Delhi. These are completely barred from entering the city, effective from November 1, 2025. This ban holds even if they are transporting essential goods.
Regional Air Quality Worsens
The pollution crisis is not confined to Delhi alone. Air quality levels in neighbouring cities have also deteriorated significantly.
- Gurgaon recorded an AQI of 347 on Friday, up from 318 a day earlier. This places it firmly in the 'Very Poor' category.
- Noida's AQI rose to 363, also 'Very Poor', from 344 on Thursday.
The IMD has also issued a weather alert for the region. A yellow alert is in place for moderate fog conditions expected in many areas on Saturday.
The situation remains critical. Residents are advised to take necessary precautions and follow the new restrictions as authorities work to manage the severe air pollution episode.
