Mumbai's Biggest Immersion Day Is Tomorrow — What Ananta Chaturdashi Means If You're Flying This Week
Ananta Chaturdashi — the final, biggest Ganpati visarjan day, including Lalbaugcha Raja — falls on September 25, 2026. If you're flying into or out of Mumbai this week, the city's traffic pattern is about to change sharply for a day.
Friday, September 25, 2026 is Ananta Chaturdashi — the final and by far the largest day of Mumbai's Ganpati visarjan season, when the city's most iconic idols, including Lalbaugcha Raja, Andhericha Raja and Chichpoklicha Chintamani, are immersed. Girgaon Chowpatty, the city's primary natural immersion site, typically sees its heaviest crowds of the entire festival on exactly this day.
Why this matters if you have a flight this week
This isn't a small local event — it's one of the highest-traffic single days on Mumbai's calendar, with road closures and diversions around processions and immersion routes that can add real time to any airport run, in either direction. If your flight — arriving or departing — falls on or near September 25, building in meaningfully more time to reach or leave Chhatrapati Shivaji Maharaj International Airport is the single most useful thing to do with this information.
It's also worth layering this against the separate international-flights shift to Navi Mumbai Airport, which begins the following week on October 1 — two changes to Mumbai's travel patterns landing back to back. We covered that shift separately if you have a booking anywhere near that date.
Planning past the festival
Once the city settles back into its routine, Trripah's Mumbai fare board is worth a look — Dubai, Rome, Bangkok, Singapore and Tokyo are all priced nightly, and fares often ease slightly in the days right after a major local event as short-notice domestic demand around it fades.
Will Mumbai traffic be affected on September 25, 2026?
Yes, significantly — Ananta Chaturdashi is the single biggest visarjan day of the festival, with major road diversions around procession and immersion routes across the city.
Should I change my flight time if I'm flying on September 25?
Not necessarily change it, but plan extra travel time to and from the airport that day — the traffic impact is real and well-documented in past years on this specific date.
