Mumbai vs Chennai
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Mumbai leads on any axis where its bar is higher, Chennai where its is. The cost bar uses a higher-is-cheaper scale, so Chennai's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Mumbai | Chennai |
|---|---|---|
| Livability | 53 | 51 |
| Cost (higher=cheaper) | 39 | 41 |
| Climate | 68 | 57 |
| Safety | 53 | 57 |
| Summer °C | 30.5 | 32.6 |
| Winter °C | 24.1 | 24.4 |
| Top disaster risk | storms (hurricane/cyclone) | storms (hurricane/cyclone) |
Mumbai vs Chennai: the short answer
Mumbai comes out ahead on overall livability (53/100), only marginally above Chennai (51/100). The two cities diverge most on climate. On affordability Chennai is the cheaper base — nearly identical prices on our cost index (Mumbai 39 vs Chennai 41, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Chennai runs warmer in summer (about 32.6°C peak vs 30.5°C in Mumbai), while winter lows sit near 24.1°C in Mumbai and 24.4°C in Chennai. On natural-disaster exposure Chennai is the safer choice (safety 57/100); the dominant modelled hazard is storms (hurricane/cyclone) for Mumbai and storms (hurricane/cyclone) for Chennai.
Which city should you choose?
- On a tight budget → Chennai — lower everyday costs..
- You want warmth → Chennai — hotter summers.
- Safety is the priority → Chennai — lower disaster risk.
- Best all-rounder → Mumbai — highest overall livability.
Data & methodology
Cost scores are normalised from World Bank price-level data. Climate figures (summer highs, winter lows) are drawn from 1991–2020 climate normals. Disaster-safety blends USGS earthquake history (magnitude 4.5+ within 300 km since 1980), tropical-cyclone basin position, flood/elevation exposure and Köppen climate zone. The livability score is the weighted composite of cost, climate and safety. All figures are planning indicators for 2026, not guarantees — verify specifics before relocating.
