On December 15, 2025, Delhi experiences cool weather with hazy sunshine and persistent smog, temperatures ranging from mild afternoon highs to chilly nights, hazardous air quality, dense fog early morning, health advisories in effect, and precautions advised for all residents.
Air Quality Index remains hazardous and smog persists.
New Delhi: Today in Delhi, skies remain mostly hazy with sunlight filtered through a layer of mist and smog, creating subdued winter visibility. Early morning started with orange alert conditions for fog, making travel and outdoor activities challenging at first light. As the day progresses, the maximum temperature in the capital is expected to reach around 21 degrees Celsius in the afternoon, offering mild conditions compared to the winter chill of previous days. Later in the evening, temperatures are forecast to drop again toward a cool night around 14 to 15 degrees Celsius, continuing the typical winter cycle of significant day and night temperature variation.
During the early hours of Monday, dense fog is predicted to linger in various parts of the city, significantly limiting visibility for commuters and motorists. The fog, a result of cold air near the surface trapping moisture and pollution, is expected to gradually dissipate as the day advances. Hazy conditions will remain widespread, and drivers are advised to use fog lights and exercise caution on highways and city streets until visibility improves.
By mid to late afternoon, the hazy sunshine will warm up the city slightly, pushing temperatures into the low twenties Celsius. Although the air may feel pleasant in direct sunlight, the cool breeze and underlying smog will keep outdoor conditions crisp. This mild afternoon weather may tempt residents to spend time outside, but precautions are still necessary due to the compromised air quality in many areas.

As twilight sets in, temperatures will gradually dip, bringing back the winter chill after sunset. The cool night air, combined with lingering haze, may make it feel colder than actual readings. Residents are advised to wear warm clothing as temperatures fall toward the mid teens. Jackets, sweaters, and scarves are recommended to maintain comfort and prevent cold related discomfort or illness during the evening and night.
Delhi’s air quality continues to be a serious concern as the Air Quality Index has reached hazardous levels in recent days, with many monitoring stations recording readings in the ‘severe’ category due to winter smog and stagnant atmospheric conditions. Authorities have implemented strict anti pollution measures under the Graded Response Action Plan to curb emissions and protect public health. Residents are strongly advised to limit outdoor activities, especially children, older adults and those with respiratory or cardiovascular conditions. When stepping outside, the use of protective face masks can help reduce inhalation of harmful particulate matter.

With air quality remaining poor and smog persistent, health concerns are heightened. Prolonged exposure to polluted air can aggravate asthma, bronchitis and other respiratory issues. Vulnerable groups should avoid outdoor exertion, and even healthy individuals may consider reducing time spent in open air. Drinking warm fluids, maintaining hydration, and using air purifiers at home can help mitigate the effects of pollution. Those with symptoms such as coughing, throat irritation, or eye discomfort should seek appropriate rest and medical advice if conditions persist.
Given today’s weather and pollution status, residents planning errands or outdoor plans should be mindful of both visibility challenges and air quality conditions. Early morning fog may delay travel, while poor AQI suggests limiting physical exertion outdoors. Combining awareness of the temperature range with precautions against smog exposure will help residents navigate the day safely.
