A significant drop in temperatures is sweeping across much of India. The India Meteorological Department (IMD) has issued alerts for dense fog in northern states and cold wave conditions in central and peninsular regions until at least December 14.
Delhi and the National Capital Region (NCR) are experiencing milder-than-expected temperatures but are not spared from the thick morning fog affecting daily commutes. On Friday, the IMD forecast partly cloudy skies over Delhi with shallow morning fog.
Temperatures are expected to remain steady, with minimums ranging from 7 degrees Celsius to 9 degrees Celsius and maximums between 23 degrees Celsius and 25 degrees Celsius, slightly above the seasonal average for mid-December.

Beyond the capital, conditions are more severe. Uttar Pradesh is expected to witness ‘very dense fog’ today. Many areas in the state witnessed a near zero visibility. Dense fog is likely in Haryana, Chandigarh, Delhi, Punjab, Odisha, and northeastern states including Assam, Meghalaya, Manipur, Mizoram, Tripura, and Nagaland at varying intensities through December 16.
