Mumbai’s Earliest Monsoon in 75 Years Brings Heavy Rainfall and Disrupts Flight Operations
Mumbai is facing an extraordinary weather event as the city experiences its earliest monsoon onset in 75 years. The heavy rainfall, which began on May 26, 2025, has caused widespread disruptions to flight operations, railway services, and road traffic. With the southwest monsoon arriving much earlier than usual, travelers, residents, and businesses are dealing with significant challenges. Here’s a detailed look at what’s happening, why it matters, and what you need to know if you’re affected by the situation.
What’s Happening: The Earliest Monsoon Onset in Decades
The India Meteorological Department (IMD) has confirmed that the monsoon arrived in Mumbai on May 26, 2025. This is the earliest arrival since records began, beating previous early onsets of May 29 in 1956, 1962, and 1971. Normally, the monsoon reaches Mumbai around June 11, so this year’s early arrival is highly unusual.
Why is this important? The early and intense monsoon onset has led to heavy rainfall across Mumbai, causing waterlogging, flooding, and major disruptions to transportation. The city’s infrastructure, already stretched during normal monsoon seasons, is under even more pressure due to the unexpected timing and intensity of the rain.
How Much Rain Has Fallen?
Between 8:30 AM and 11:30 AM on May 26, several areas in Mumbai recorded significant rainfall:
- Nariman Point: 104 mm (with 104 mm falling in just one hour between 9 AM and 10 AM)
- Colaba: 105.2 mm
- Bandra: 68.5 mm
- Juhu Airport: 63.5 mm
- Santacruz: 55 mm
- Sion: 53.5 mm
- Malabar Hill: 63 mm
- CSMT: 80 mm
The Brihanmumbai Municipal Corporation (BMC) reported that the island city received an average of 58 mm of rain in the 24 hours ending at 8 AM. In comparison, the eastern suburbs got 19 mm, and the western suburbs received 15 mm. These numbers show just how much heavier the rain has been in the city center compared to the outskirts.
Flight Operations: Major Disruptions at Mumbai Airport
The heavy rainfall has had a severe impact on flight operations at Chhatrapati Shivaji Maharaj International Airport. Over 250 flights have been affected, with delays and cancellations causing frustration for thousands of travelers.
Airlines Respond: Advisories and Warnings
IndiGo:
IndiGo, one of India’s largest airlines, issued a statement saying, “Due to heavy rains in Mumbai, several flights have been impacted, and we deeply regret any disruptions to your travel plans. We are doing everything possible to manage the situation and minimize the delays. We’re all hands on deck to ensure that you reach your destination safely and as quickly as possible.”
IndiGo also advised passengers to allow extra time to reach the airport because of waterlogging and to check their flight status regularly on the airline’s website.
SpiceJet:
SpiceJet warned passengers, “Due to bad weather (heavy rain) in Mumbai (BOM), all departures/arrivals and their consequential flights may get affected. Passengers are requested to keep a check on their flight status via http://spicejet.com/#status.”
The airline also pointed out that even flights not directly connected to Mumbai could be delayed because of the way aircraft are rotated between routes.
Air India:
Air India issued a travel advisory as well, stating that they are working to minimize inconvenience for passengers and are closely monitoring the situation.
What Should Passengers Do?
If you are flying to or from Mumbai during this period, here are some important steps to follow:
- Check your flight status before leaving for the airport. Use the airline’s website or official app for real-time updates.
- Allow extra travel time to the airport. Waterlogging and traffic jams are common during heavy rain, and it may take much longer than usual to reach the terminal.
- Stay in touch with your airline’s customer service for the latest information and possible rebooking options.
- Monitor weather updates from the IMD and local news sources for any changes in the situation.
Other Transportation Impacts: Railways and Roads
Railway Services
Mumbai’s local train network is the city’s lifeline, but the heavy rain has caused problems here too.
- Central Railway: Waterlogging has been reported at several stations, including Masjid, Byculla, Dadar, Matunga, and Badlapur. Trains are running at reduced speeds, with delays of 8 to 10 minutes due to low visibility and water on the tracks.
- Western Railway: Officials claim that services are running normally, but many commuters have reported delays on social media.
Road Traffic
Road traffic in Mumbai has been badly affected by waterlogging and poor visibility. Some of the worst-hit areas include:
- King’s Circle
- Mantralaya
- Dadar TT East
- Parel TT
- Kalachowki
- Dadar station
- Dadar Hindmata area
Drivers are facing long delays, and many roads are flooded, making travel difficult and sometimes dangerous.
Weather Warnings and Government Response
The IMD has issued orange and red warnings for Mumbai and nearby areas, predicting moderate to heavy rainfall, thunderstorms, and squally winds of 50-60 kmph over the next few hours. The weather agency has also warned about the possibility of lightning and intense rain at isolated places in Mumbai during the next 3-4 hours.
In response, the Maharashtra Government has ordered the relocation of 3,100 people to safer areas as a precaution against flooding and cloudbursts.
Historical Context: Why This Monsoon Is Different
This year’s monsoon is not just early—it’s also much heavier than usual for May. According to IMD scientist Sushma Nair, the previous earliest monsoon arrivals in Mumbai were on May 29 in 1956, 1962, and 1971. This year’s arrival beats those records by three days. The typical monsoon onset date for Mumbai is June 11, so this event is highly unusual.
Some reports have called this Mumbai’s “wettest May in over 100 years,” showing just how rare and intense the current rainfall is. The IMD has warned that more thunderstorms and gusty winds are likely in the next 48 hours, so the disruptions may continue.
Implications for Stakeholders
Travelers and Passengers
The biggest impact is on travelers, especially those flying in or out of Mumbai. With over 250 flights affected, many people have faced delays, missed connections, and last-minute changes to their plans. Airlines are working to help passengers, but the situation remains unpredictable.
Airlines and Airport Staff
Airlines like IndiGo, SpiceJet, and Air India have had to adjust their schedules, rebook passengers, and manage customer service challenges. Airport staff are working overtime to help travelers and keep operations running as smoothly as possible.
Local Residents
For people living in Mumbai, the early monsoon has brought both relief from the summer heat and new problems. Waterlogging, traffic jams, and train delays are making daily life more difficult. Some families have had to leave their homes because of flooding.
Businesses and Employers
Businesses that rely on travel and transportation are also affected. Delays in shipments, employee absences, and supply chain disruptions are likely as the city deals with the effects of the heavy rain.
What Can You Do? Practical Guidance
If you are in Mumbai or planning to travel there, here are some steps you can take to stay safe and minimize disruption:
- Check your flight status regularly. Use the airline’s official website or app for the most accurate information.
- Leave early for the airport or train station. Allow extra time for delays caused by waterlogging and traffic.
- Keep emergency supplies handy, such as water, snacks, and a phone charger, in case you get stuck in traffic or at the airport.
- Stay informed by following updates from the IMD, local news, and your airline.
- Follow government advisories and move to safer areas if asked by authorities.
The Bigger Picture: Climate and Urban Challenges
Mumbai’s early and intense monsoon highlights some of the bigger challenges facing the city. Rapid urban growth, aging infrastructure, and changing weather patterns all play a role in making the city more vulnerable to flooding and transportation problems.
Why does this matter for immigration and global mobility? Mumbai is a major hub for international travel, business, and migration. Disruptions to flight operations can affect not just local residents but also people traveling for work, study, or family reasons. According to analysis by VisaVerge.com, weather-related disruptions in major cities like Mumbai can have ripple effects on visa appointments, immigration interviews, and travel plans for people from around the world.
