Mumbai Rains Today: What’s Happening, What’s Shut, and How to Stay Safe

By 7 am, most of us had already checked the sky twice. You could hear it in housing society corridors—the thud of wet umbrellas, the shuffle of raincoats, kids negotiating whether school would be open. The rain wasn’t the dramatic, one-shot cloudburst. It was the steadier kind that keeps returning just when you think it’s done.

Through the morning, the city felt familiar yet slightly heavier. Office-goers left early and still inched forward. Auto drivers argued gently about routes (because who wants to risk a stalled engine), and chai stalls did brisk business. It was one of those dependable Mumbai monsoon days when the city doesn’t stop; it simply learns to move slower.

What changed between morning and noon

The weather office started the day with a red alert—that’s the strongest kind—and then eased it to orange as the day wore on. In plain English: “We expect very heavy rain in some places; take it seriously.” The outlook for the next day dialled down another notch to yellow, which means showers can be heavy in pockets, but the overall risk usually drops a bit. Think of it as a traffic signal: red (extreme caution), orange (careful planning), yellow (stay alert but you can move).

The numbers—kept simple

Mumbai’s two main observatories showed a clear picture for the last 24 hours: Santacruz around the mid-80 mm mark, Colaba a little over 50 mm. That alone is healthy monsoon rain, but the finer stations told a sharper story. Dahisar was hammered (close to 190 mm), Kandivli crossed 150 mm, while Vikhroli–Bhandup, Parel, and Cotton Green also registered strong spells. In short, the suburbs took more than the island city this time.

Through the season, both observatories have already crossed the 1,000 mm milestone—Colaba past 1,200 mm and Santacruz well over 1,700 mm—which is why any fresh burst shows up as waterlogging quickly. The ground is saturated; drains are already busy. A sharp hour like 9–10 am in Chembur (around 65 mm) can tip a neighbourhood from “wet” to “underwater” without much notice.

So, what actually got disrupted?

1) Roads and underpasses

If your route touched the Western Express Highway near Vile Parle, you probably crawled. Hindmata is a regular trouble spot and it behaved exactly the way old-timers warned you it would. Patches across Dadar, parts of the Wadala Freeway, sections in Chembur, and around Gandhi Market stayed soggy long enough to trigger diversions. And yes, the Andheri Subway had to be shut temporarily—classic monsoon scene.

Tip you’ll thank yourself for: before leaving, check a live map and zoom into underpasses on your route. If there’s water there, go around. Two extra kilometres are better than a flooded engine and a tow bill.

2) Local trains—the city’s heartbeat, just slower

Trains ran, which is the best sentence a Mumbaikar can read on a rain day, but 15–20 minutes late in patches. On Harbour and parts of the Central line, staff physically watched the water line on the tracks at Kurla, Govandi, Mankhurd, Tilak Nagar—boots on the ground, keeping the network safe. If you had to switch lines today, you needed patience and a power bank.

Small hack: when platforms are packed, take a reverse train one stop to grab a seat and then come back the way you need. It sounds odd but saves you from being wedged against a door for 40 minutes.

3) BEST buses—detours that actually help

Buses don’t like deep water (who does?). So diversions in Chembur, Sion, Kurla, Wadala, Antop Hill, Hindmata kept services moving, even if the bus you were waiting for never appeared at that exact stop. If you saw the bus skipping a flooded halt, it wasn’t being rude; it was staying alive.

4) Flights—plan for extra minutes

Airlines advised fliers to reach early. A few aircraft had go-arounds—that’s the standard safety drill when visibility, wind or rain misbehave. If you were tracking someone’s landing on your phone, you likely saw the aircraft circle and try again. Normal for a day like this.

Why does the city flood so quickly? Four simple reasons

1. Speed of rain: When the sky drops 50–70 mm in an hour, even a well-kept system groans.
2. High tide: Outflow slows when the sea is pushing back.
3. Blocked grates: Leaves, plastic, everyday city life—anything sitting on drain covers is bad news in heavy rain.
4. Saturated ground: After weeks of monsoon, the sponge is already full. New water has fewer places to go.

Put these four together and you get that familiar monsoon snapshot: bikes moving with legs lifted, a BEST bus inching through a flat brown sheet, and a cluster of cars waiting for the brave one to lead.

Afternoon call: Why BMC shut schools and colleges (second session)

The decision was straightforward: keep students safe, cut the number of people on the road, and let emergency teams focus where water was collecting. Morning sessions ran, but post-noon schools and colleges were closed. If you had a coaching class later, most places either rescheduled or switched to online for the day.

Neighbourhood watchlist (based on today’s pattern)

• Western/Eastern suburbs: Dahisar, Kandivli, Bhandup, Vikhroli saw heavier bursts.
• South-central pockets: Cotton Green, Parel, Lower Parel had their own rain windows.
• Underpasses/low-lying lanes: Andheri Subway and similar dips flood fast—avoid them even if traffic looks temporarily clear.

If you live near a nalla or in a lane that slopes down to the main road, ask your security to keep an eye on the basement pumps and lift lobbies. Water sneaks in quietly; you want to notice it early.

The next 24–48 hours, decoded

• Later today: Expect phases—long, manageable showers, then a 3–4 hour heavy burst somewhere. Plans should stay flexible.
• Tomorrow: The alert settles to yellow. That doesn’t mean bright sunshine; it means risk spread is lower and intense cells are fewer. Still carry an umbrella. Still avoid underpasses at high-tide hours.

If you must travel—do this, exactly

• Check maps and official handles ten minutes before stepping out. Conditions swing by the hour.
• Avoid flooded underpasses even if someone ahead gets through. Your car may not sit as high as theirs.
• Shoes with grip over fancy footwear. Metal covers and tiles are treacherous when wet.
• Electronics up high in your bag; zip-lock pouches cost little and save a phone.
• If your car stalls, don’t keep cranking. Push to the side and call for help. Multiple attempts can wreck the engine.
• For trains, add 20–30 minutes and bring a power bank and a spare cable.
• Keep a small snack and water. A 20-minute delay can turn into an hour when a cell parks over your route.

Safety checklist you can pin on your society board

• Don’t wade through moving water. Standing water is bad; moving water is worse.
• Keep children at home unless travel is essential.
• Watch for open manholes; in heavy flow, covers can shift.
• If water enters a lift lobby, stop elevator use till everything is cleaned and checked.
• Park on higher ground if your basement is known to flood.
• Fill a small bag with a torch, battery bank, and dry snacks.
• Emergency numbers: 100 / 112 and local BMC ward control room. Save them now; when you need a number, you won’t want to search.

For parents and students

With the afternoon off, many coaching centres moved classes online. If your child still has to step out, write a contact number on a slip and put it in their pocket. Phones die at the worst time. A simple note helps more than we admit.

For office teams and small businesses

• Flexible timings so staff can avoid the worst window.
• Shift non-urgent meetings online.
• Keep entry mats and a wet floor sign—one slip wastes a week of productivity.
• Create a small WhatsApp commute channel so teammates broadcast jams or flooded stretches in real time.

For flyers and airport pickups

Leave earlier than you think you need to. If you’re picking someone up, track the flight but don’t rely only on the ETA; a go-around adds a few minutes and looks scary on the map but it’s routine safety on days like these. Keep your tank at least half full—idling in traffic with the AC on drains fuel more than you expect.

A city that helps itself, quietly

A rain day always exposes Mumbai’s weak points—drain covers that need a redesign, choked spots that haven’t been fixed yet. But it also reveals the good stuff. Shopkeepers pulling their shutters halfway for people to stand under. The bus conductor who warns a cyclist about a puddle that’s deeper than it looks. Neighbours passing down umbrellas to kids at the gate. The city is tough because people are kind in small, almost invisible ways.

Conclusion

This wasn’t the loudest monsoon day of the decade, but it demanded respect. Red to orange alerts, waterlogging in usual suspects, school closures, train delays, and flight advisories—the full Mumbai checklist. The forecast for tomorrow looks lighter on risk, not rain. Keep your plans flexible, keep your shoes dry, and keep your patience handy. The city will catch up with itself, as it always does, one cleared puddle at a time.
