The Bengal dense fog IMD warning 2026 has drawn attention to the changing winter weather patterns in the state. The India Meteorological Department (IMD) forecasted dense fog conditions in both North and South Bengal over the next few days, accompanied by a rise in minimum temperatures. This dual phenomenon—foggy mornings and warmer nights—reflects the complex interplay of climate variability, urbanisation, and atmospheric changes.
2. IMD’s Forecast
- Dense fog expected in districts of North Bengal (Darjeeling, Jalpaiguri, Cooch Behar, Alipurduar) and South Bengal (Kolkata, Howrah, Hooghly, Burdwan).
- Fog likely to persist during early morning and late night hours.
- Minimum temperatures to rise by 2–3°C compared to last week.
- IMD warned of visibility hazards for road and rail transport.
3. Why Fog Forms in Bengal Winters
- Moisture accumulation in the atmosphere due to river basins (Ganga, Teesta).
- Temperature inversion trapping pollutants and moisture near the surface.
- Urban heat islands in Kolkata and Siliguri intensifying fog density.
- Deforestation and land use changes altering microclimates.
4. Impact on Daily Life
- Transport disruptions: Delays in trains, flights, and buses.
- Road accidents due to poor visibility.
- Health concerns: Respiratory issues aggravated by fog mixed with pollutants.
- Agriculture: Fog affects crop growth, especially vegetables and mustard.
5. Governance Challenges
The IMD warning highlights systemic governance issues:
- Weak infrastructure for fog management (e.g., runway lighting, highway sensors).
- Lack of awareness campaigns for rural communities.
- Need for coordination between meteorological agencies and local governments.
- Climate adaptation policies still underdeveloped in Bengal.

7. Historical Context of Fog in Bengal
- 2000s: Dense fog frequently disrupted train schedules in North Bengal.
- 2010s: Kolkata witnessed rising pollution levels, worsening fog intensity.
- 2020s: Climate variability led to warmer winters with patchy fog.
- 2026: Current IMD warning reflects a shift towards foggy but less cold winters.
8. Community Impact
- Commuters expressed frustration at train delays and traffic jams.
- Farmers worried about crop damage and delayed harvests.
- Students faced difficulties attending early morning classes.
- Civil society groups demanded better forecasting and public communication.
9. Global Comparisons
Similar fog‑related challenges worldwide:
- China: Dense smog‑fog mix in Beijing disrupts daily life.
- UK: Historic “London fog” linked to coal smoke and moisture.
- USA: Midwest fog events cause highway pile‑ups.
Bengal’s case mirrors these global struggles where fog intersects with pollution and climate change.
10. Governance Lessons
The IMD warning teaches:
- Early warning systems must be strengthened.
- Public awareness campaigns can reduce accidents.
- Technology (fog sensors, GPS alerts) should be deployed on highways.
- Climate adaptation policies must integrate fog management.
11. Future Outlook – Climate Preparedness in Bengal
India must move towards:
- Digitised weather dashboards accessible to citizens.
- Smart traffic systems to manage fog disruptions.
- Community‑based climate education in rural districts.
- Cross‑regional cooperation with neighbouring states for coordinated forecasting.
12. Bengal Dense Fog IMD Warning 2026: Conclusion
The Bengal dense fog IMD warning 2026 is more than a weather forecast—it is a reminder of the state’s vulnerability to climate variability. Dense fog combined with rising minimum temperatures signals a changing winter pattern that demands governance reforms, technological adaptation, and community resilience. For Bengal, the lesson is clear: climate preparedness must be proactive, inclusive, and science‑driven.
