Nine Mumbai-bound flights were diverted to Surat International Airport on Tuesday evening, September 29, 2026, after severe weather conditions made landing at Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) highly hazardous. The weather brought torrential rain, gusty high-velocity winds, heavy downpours, strong crosswinds and lightning. The incident resulted in a new record for single-day flight diversions handled by Surat International Airport. In total, the nine diverted flights carried 1,482 passengers, and the airport teams worked through the evening to land, park and support every aircraft safely while continuing their regular scheduled operations.
Why Were Mumbai-Bound Flights Diverted?
An intense storm over Mumbai on Tuesday evening created difficult conditions for aircraft attempting to land at CSMIA. Heavy rain, strong crosswinds and lightning led the Air Traffic Control (ATC) to halt landing operations as a critical safety measure. With aircraft unable to land safely in Mumbai, incoming flights were systematically redirected to nearby secondary airports, primarily Surat and Vadodara, between 6:50 PM and 8:45 PM. As a result, nine Mumbai-bound flights were sent to Surat International Airport. The decision to divert was taken purely on safety grounds, as landing in such conditions would have put both passengers and aircraft at risk.
9 Flights Carried 1,482 Passengers
The nine flights diverted to Surat carried a combined total of 1,482 passengers. The diverted flights were operated by two major domestic carrier groups:
- IndiGo: 6 diverted flights
- Air India Group: 3 diverted flights
The flights had originated from several major domestic and international hubs before heading towards Mumbai. This mix of origins shows how the weather disruption affected not just one route but multiple incoming flights from different parts of the country.
Cities From Which the Flights Originated
The diverted flights came from several cities, which gives a clear picture of how widespread the impact of the Mumbai weather was on that evening. The listed origins were:
- Delhi: 2 flights
- Chennai: 2 flights
- Bengaluru: 1 flight
- Bhopal: 1 flight, including an IndiGo flight carrying 204 passengers
- Goa: 1 flight
- Coimbatore: 1 flight
- Tiruchirappalli (Trichy): 1 flight
In addition to the nine flights diverted to Surat, another four Mumbai-bound flights from cities including Hyderabad, Vijayawada and Indore were diverted to Vadodara Airport. Together, these diversions affected 13 flights in total, showing the scale of the disruption caused by the severe weather over Mumbai that evening.
Surat Airport Handled the Additional Air Traffic
The sudden diversion brought nearly 1,500 unscheduled passengers to Surat Airport. Despite the unexpected increase in passenger numbers, Surat Airport managed the additional air traffic without disrupting its existing scheduled flights. Airport teams, safety officials and airline personnel coordinated to land and park all nine diverted aircraft safely. The unexpected diversions also meant that passengers had to remain at the airport for several hours while waiting for conditions in Mumbai to improve. Managing such a large, unplanned influx of aircraft and passengers in a short window required careful coordination between multiple agencies.
Drinking Water and Refreshments Arranged for Passengers
Because passengers were waiting on-site for hours, the Surat Airport Authority arranged complimentary drinking water and refreshments. The support was provided while the aircraft remained at Surat Airport and passengers waited for the weather conditions in Mumbai to normalize. Later that night and into the following morning, atmospheric and wind conditions over Mumbai improved. Once conditions normalized, the aircraft were cleared to depart from Surat and continue their journeys to Mumbai. This passenger support was an important part of the overall response, as it helped reduce discomfort for the nearly 1,500 people who were unexpectedly stranded at the airport.
A New Single-Day Diversion Record for Surat Airport
The diversion of nine Mumbai-bound flights marked a new record for single-day flight diversions handled by Surat International Airport. The incident involved a sudden influx of aircraft and passengers while the airport continued its existing scheduled operations. The coordinated handling of the nine diverted aircraft included landing, parking and passenger support until the flights were cleared to continue their journeys. This record highlights the growing operational capacity of Surat Airport and its ability to step in as a reliable alternative when weather disrupts operations at a major hub like Mumbai.

What Passengers Need to Know
For air travellers, this incident highlights how quickly weather can change flight plans, especially during the post-monsoon period when sudden storms are common. When ATC halts landings at a major airport like Mumbai, flights are redirected to nearby airports such as Surat and Vadodara, and passengers may need to wait several hours before continuing their journey. Airlines and airport authorities typically provide basic support like drinking water and refreshments during such waits. Passengers travelling to or from Mumbai during the monsoon and post-monsoon months should keep some flexibility in their plans and stay updated on weather conditions and flight status through their airline’s official channels.
Conclusion
The diversion of nine Mumbai-bound flights to Surat International Airport on September 29, 2026, followed severe weather conditions over Mumbai that made aircraft landings hazardous. Heavy rain, strong crosswinds, gusty winds and lightning led ATC to halt landing operations at CSMIA. The nine diverted flights carried 1,482 passengers, with six operated by IndiGo and three by the Air India Group. Surat Airport coordinated the landing and parking of all nine aircraft while continuing its scheduled operations and arranging complimentary drinking water and refreshments for waiting passengers. After atmospheric and wind conditions over Mumbai normalized later that night and into the following morning, the aircraft were cleared to leave Surat and complete their journeys to Mumbai.
