New Delhi, September 26, 2025 – Delhi has another warm and sunny day today, with temperatures ranging from 36-37°C, and air quality continues to be a cause of concern for citizens throughout the city. The association of the growing temperatures with poor air quality has led health authorities to recommend advisory notices for susceptible populations.
Weather Overview
As per the India Meteorological Department (IMD), Delhi experienced clear sky and low humidity in the morning hours, with the mercury likely to touch a maximum of 37°C in the day. Nights are also quite warm, with temperatures not falling below 27°C, which is an unusually warm stretch for late September.
Residents have been cautioned to avoid direct sun exposure for extended periods and are advised to stay hydrated, especially between 11 a.m. and 4 p.m., when the intensity of heat is highest.
Air Quality Issues
Despite the sunny, warm conditions, air quality in Delhi continues to be bad. The Central Pollution Control Board (CPCB) has said that particulate matter (PM2.5) levels are higher than safe and thus marked the city’s air as “poor” on the AQI scale.
Dr. Anjali Mehra, an air quality expert, said, “The city is not facing severe smog at the moment, but the leftover pollutants from construction, traffic, and industries are maintaining AQI levels at a high point. Respiratory patients, children, and the elderly should restrict their outdoor activities.
The increase in air pollution is also attributed to persistent regional sources, such as burning crop residue in surrounding states and vehicle emissions, that persist in causing poor visibility and respiratory irritation.
Health Advisory
Medical professionals have encouraged residents to exercise caution in the face of the combined heat and pollution effects:
Stay indoors, especially for strenuous exercises.
Wear masks while outdoors, particularly for asthma or other breathing disorders.
Close windows during rush hours to minimize indoor exposure to pollution.
Drink plenty of water and ensure balanced nutrition to counteract heat stress.
Hospitals saw a moderate increase in patients with respiratory distress and heat disorders, highlighting the importance of public education and preventive action.
Looking Ahead
The IMD predicts that Delhi will keep witnessing hot temperatures with sunny intervals in the coming days. There will be no substantial rainfall, which could extend the duration of high temperature and poor air quality. Citizens are recommended to keep an eye on weather reports and AQI notifications to protect their health.
Community Response
Local residents and environmental activists have demanded immediate measures to enhance air quality, such as the tighter control of construction dust, emissions from vehicles, and open waste burning. Residents have also taken interim steps like using air purifiers at home and curtailing outdoor movements during high pollution periods.
As Delhi undergoes the ordeal of hot weather and smog, specialists emphasize the need for individual measures and mass consciousness. While the city basks in sunshine and transparent skies, there lingers the silent danger of pollution, which still waits in ambush to unleash its health-hazardous attacks on sensitive communities. Both governments and citizens are called upon to stay alert and active as they tackle the combined effect of heat and pollution.
