Overview
- Delhi recorded a minimum of 4.2°C at Safdarjung on Saturday, edging past Friday’s 4.6°C for the season’s new low and the coldest January reading in two years, according to IMD data.
- Air quality deteriorated to the very poor range, with the citywide 24-hour AQI in the mid‑300s and several stations touching severe levels, as high humidity and weak winds trapped pollutants near the surface.
- Low visibility slowed flight operations at Delhi’s IGI and Hindon airports, with CAT III procedures in use and advisories from airlines such as IndiGo and Air India warning of delays and schedule changes.
- IMD kept Delhi under a yellow alert for dense fog and cautioned of cold wave or cold day conditions across parts of north and central India, forecasting continued morning and late‑night visibility drops.
- A separate system over the Bay of Bengal prompted orange alerts for heavy to very heavy rain and squally seas along Tamil Nadu and Puducherry, with fishermen advised to avoid rough to very rough waters.
