New Delhi: The India Meteorological Department (IMD) predicts mostly clear skies for Delhi today, although a layer of smog has settled over certain parts of the city. The minimum temperature is expected to drop to 19 degrees Celsius, providing a cool and pleasant atmosphere for residents. With no rain forecasted, it looks to be a dry day ahead. However, due to rising pollution levels, anti-pollution measures outlined in the Graded Response Action Plan (GRAP)-II were implemented earlier this week.

Weekly Weather Forecast
The seven-day weather outlook for Delhi indicates predominantly clear skies, with daytime temperatures ranging from 32 to 34 degrees Celsius and nighttime temperatures between 18 and 19 degrees Celsius. Wind speeds will vary from 4 km/h to 18 km/h, mainly coming from the northwest, northeast, and southeast. From October 26 onward, mornings may see light mist, but clear skies are expected throughout the day. No significant weather events are anticipated during this period, ensuring pleasant conditions for residents.

Delhi AQI
According to the latest data from the System of Air Quality and Weather Forecasting and Research (SAFAR), Delhi's Air Quality Index (AQI) was in the "Very Poor" category as of 7 a.m. The air quality showed slight improvement on Thursday due to increased wind speeds that helped disperse some pollutants; however, the AQI still registered at 306, down from 364 the previous day. Nevertheless, pollution levels in Delhi remain the highest in the country, according to the Central Pollution Control Board (CPCB).

Areas such as Dwarka, Rohini, Anand Vihar, IGI Airport (T3), Mundka, and several others reported "very poor" AQI levels. In contrast, the air quality in neighboring regions like Faridabad, Noida, Gurugram, and Greater Noida was slightly better, classified as "poor."

The AQI is categorized into four stages: Stage I is "Poor" (AQI 201-300), Stage II is "Very Poor" (AQI 301-400), Stage III is "Severe" (AQI 401-450), and Stage IV is "Severe Plus" (AQI above 450).

What is PM 10?
PM 10 refers to particulate matter with a diameter of 10 micrometers or less. These tiny particles, whether solid or liquid, can be inhaled deep into the lungs. Sources of PM 10 include dust, pollen, mold, vehicle exhaust, and industrial emissions, which can lead to respiratory problems such as asthma and bronchitis. Prolonged exposure to PM 10 can also increase the risk of heart and lung diseases.
