Mumbai recorded temperatures 5°C below the seasonal average, giving residents a rare and refreshing break from the city’s usual humidity and warmth.
The sudden dip led many to believe winter had arrived early — but meteorologists say it’s not winter yet.
According to early analysis, this drop is due to changing wind patterns and temporary climatic conditions, not the onset of a long winter phase.
Why Did Mumbai’s Temperature Suddenly Drop?
Experts highlight a combination of weather factors:
1. Dry Northerly Winds
Cool, dry winds from northern India briefly reached the city, replacing the usual warm, moisture-heavy sea breeze.
2. Clear Skies at Night
Clear skies cause heat to escape faster, leading to colder nights and early mornings.
3. Post-Monsoon Transition
Mumbai often sees short cool spells as it shifts from humid monsoon weather to dry winter conditions.
4. Weak Sea Breeze
On certain days, the sea breeze arrives late or remains weak, reducing coastal warmth.
These factors combined to create a noticeable temperature drop.
Why This Is Not Early Winter
Despite the sharp fall, meteorologists caution against calling this “winter”.
✔ Temporary Weather Pattern
Mumbai’s winter is mild and usually begins in late December.
✔ No Major Pressure System Change Yet
Winter winds strengthen only when northern India gets stable high-pressure conditions.
✔ Humidity Expected to Rise Again
Humidity and temperatures will likely increase once sea winds return.
✔ Urban Heat Retention
The city’s concrete landscape still traps heat — a hallmark of Mumbai winters.
So, while the city may be enjoying a cool spell, a sustained winter-like trend is not here yet.
How Residents Reacted
Mumbai residents welcomed the cooler mornings and evenings:
Joggers and walkers noted fresher early hours
Less air-conditioning and fan usage
Better outdoor comfort
However, the change caught many off guard, leading to a slight uptick in cold, cough and throat irritation due to sudden temperature shifts.
What’s Expected Next?
Weather experts predict:
Temperature will rise again gradually
More fluctuations in coming weeks
Real winter effect only from late December
Cooler nights but warm afternoons in early December
Mumbai’s winter pattern always comes in short bursts rather than long spells.
