Delhi’s Fog: A Seasonal Challenge
Delhi’s geographical location and climatic conditions make it prone to dense fog, particularly during the winter months from December to February. Several factors contribute to this phenomenon:
- Low Temperatures and High Humidity: The winter months bring a significant drop in temperature, often accompanied by high humidity. This creates favorable conditions for condensation, forming tiny water droplets that hang in the air as fog.
- Lack of Wind: Delhi experiences very little wind during winter, especially at night and in the early morning. This lack of air circulation allows the fog to settle and thicken, reducing visibility significantly.
- Pollution Levels: The city’s high pollution levels exacerbate the fog situation. Particulate matter in the air provides condensation nuclei, allowing water vapor to condense more easily and form thicker fog.
How Delhi Airport Manages Fog Situations
Delhi Airport employs various measures to ensure safety and minimize disruptions during foggy conditions:
Advanced Navigation Systems:
The airport is equipped with advanced Instrument Landing Systems (ILS) and CAT III B technology, allowing aircraft to land even when visibility is as low as 50 meters. These systems provide pilots with precise guidance during landings and takeoffs in low-visibility conditions.

Fog Dispersal Techniques:
While not a permanent solution, Delhi Airport has explored fog dispersal techniques to improve visibility temporarily. These methods include using large fans to disperse fog and spraying warm water droplets to evaporate the fog.
Passenger Information and Assistance:
During fog situations, the airport authorities make every effort to keep passengers informed about flight statuses, delays, and alternative arrangements. Passengers are advised to:
- Check Flight Status Regularly: Stay updated on flight schedules through the airline’s website or mobile app.
- Arrive at the Airport Early: Allow ample time for check-in and security procedures, especially during fog-prone periods.
- Follow Airport Announcements: Pay close attention to announcements made at the airport regarding flight updates and gate changes.
- Contact the Airline: Reach out to the airline directly for assistance with rebooking or other travel arrangements in case of cancellations or significant delays.
