The national capital experienced a significant improvement in air quality on Saturday morning, with the Air Quality Index (AQI) dropping to 264, following substantial rainfall the previous day. This meteorological event marked the highest January rainfall recorded in Delhi over the past two years, providing much-needed respite from the severe pollution levels that had plagued the city.
Rainfall Breaks Pollution Spell
Friday's rainfall proved to be a turning point for Delhi's environmental conditions. The precipitation not only washed away particulate matter from the atmosphere but also triggered a noticeable drop in temperatures across the city. According to data from the India Meteorological Department (IMD), this rainfall event surpassed all January precipitation records since January 30, 2023, when Delhi received 20.4 mm of rain.
Air Quality Transformation
The Central Pollution Control Board (CPCB) reported that at 7 AM on Saturday, Delhi's AQI stood at 264, categorizing it as 'poor' but representing a substantial improvement from previous days when readings fluctuated between 'severe' and 'very poor' categories. The 24-hour average AQI had been recorded at 282, indicating the gradual cleansing effect of the rainfall on the city's atmosphere.
Weather Outlook for Saturday
The IMD has issued a weather forecast for Saturday predicting generally cloudy skies with shallow to moderate fog expected during morning hours. Temperature parameters are projected to range between a minimum of approximately 7 degrees Celsius and a maximum of around 17 degrees Celsius. Meteorological experts have noted that the minimum temperature is likely to decrease further as a direct consequence of the recent rainfall.
Historical Context and Future Implications
This weather event holds particular significance as it represents the most substantial January rainfall Delhi has witnessed in two years. The combination of precipitation and temperature changes has created temporary relief from the persistent air pollution that typically affects the region during winter months. While the immediate improvement in air quality is welcome, environmental scientists continue to monitor whether this represents a temporary respite or the beginning of a more sustained pattern of cleaner air for the capital region.
